## Public Member Functions

| ManualObject (const String &name)
virtual | ~ManualObject ()
virtual void | clear (void)
| Completely clear the contents of the object.
virtual void | estimateVertexCount (size_t vcount)
| Estimate the number of vertices ahead of time.
virtual void | estimateIndexCount (size_t icount)
| Estimate the number of indices ahead of time.
virtual void | begin (const String &materialName, RenderOperation::OperationType opType=RenderOperation::OT_TRIANGLE_LIST)
| Start defining a part of the object.
virtual void | setDynamic (bool dyn)
| Use before defining gometry to indicate that you intend to update the geometry regularly and want the internal structure to reflect that.
virtual bool | getDynamic () const
| Gets whether this object is marked as dynamic.
virtual void | beginUpdate (size_t sectionIndex)
| Start the definition of an update to a part of the object.
virtual void | position (const Vector3 &pos)
| Add a vertex position, starting a new vertex at the same time.
virtual void | position (Real x, Real y, Real z)

Remarks:
  A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void | normal (const Vector3 &norm)
| Add a vertex normal to the current vertex.
virtual void | normal (Real x, Real y, Real z)

Remarks:
  Vertex normals are most often used for dynamic lighting, and their components should be normalised.

virtual void | textureCoord (Real u)
| Add a texture coordinate to the current vertex.
virtual void | textureCoord (Real u, Real v)

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void | textureCoord (Real u, Real v, Real w)

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void | textureCoord (const Vector2 &uv)

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void | textureCoord (const Vector3 &uvw)

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex.

## Detailed Description

Class providing a much simplified interface to generating manual objects with custom geometry.

Remarks:
  Building one-off geometry objects manually usually requires getting down and dirty with the vertex buffer and vertex declaration API, which some people find a steep learning curve. This class gives you a simpler interface specifically for the purpose of building a 3D object simply and quickly. Note that if you intend to instance your object you will still need to become familiar with the Mesh class.

  This class draws heavily on the interface for OpenGL immediate-mode (glBegin, glVertex, glNormal etc), since this is generally well-liked by people. There are a couple of differences in the results though - internally this class still builds hardware buffers which can be re-used, so you can render the resulting object multiple times without re-issuing all the same commands again. Secondly, the rendering is not immediate, it is still queued just like all OGRE objects. This makes this object more efficient than the equivalent GL immediate-mode commands, so it's feasible to use it for large objects if you really want to.

  To construct some geometry with this object:
  1. If you know roughly how many vertices (and indices, if you use them) you're going to submit, call estimateVertexCount and estimateIndexCount. This is not essential but will make the process more efficient by saving memory reallocations.
  2. Call begin() to begin entering data
  3. For each vertex, call position(), normal(), textureCoord(), colour() to define your vertex data. Note that each time you call position() you start a new vertex. Note that the first vertex defines the components of the vertex - you can't add more after that. For example if you didn't call normal() in the first vertex, you cannot call it in any others. You ought to call the same combination of methods per vertex.
  4. If you want to define triangles (or lines/points) by indexing into the vertex list, you can call index() as many times as you need to define them. If you don't do this, the class will assume you want triangles drawn directly as defined by the vertex list, ie non-indexed geometry. Note that stencil shadows are only supported on indexed geometry, and that indexed geometry is a little faster; so you should try to use it.
  5. Call end() to finish entering data.
  6. Optionally repeat the begin-end cycle if you want more geometry using different rendering operation types, or different materials After calling end(), the class will organise the data for that section internally and make it ready to render with. Like any other MovableObject you should attach the object to a SceneNode to make it visible. Other aspects like the relative render order can be controlled using standard MovableObject methods like setRenderQueueGroup.

  You can also use beginUpdate() to alter the geometry later on if you wish. If you do this, you should call setDynamic(true) before your first call to begin(), and also consider using estimateVertexCount / estimateIndexCount if your geometry is going to be growing, to avoid buffer recreation during growth.

  Note that like all OGRE geometry, triangles should be specified in anti-clockwise winding order (whether you're doing it with just vertices, or using indexes too). That is to say that the front of the face is the one where the vertices are listed in anti-clockwise order.

Remarks:
  Certain objects may want to do specific processing based on the camera position. This method notifies them incase they wish to do this.

Reimplemented in Ogre::BillboardChain, Ogre::BillboardSet, Ogre::Entity, Ogre::Frustum, Ogre::InstancedGeometry::BatchInstance, Ogre::MovablePlane, Ogre::ParticleSystem, Ogre::SimpleRenderable, and Ogre::StaticGeometry::Region.

virtual void Ogre::MovableObject::_notifyMoved | ( | void |  | ) | `[virtual, inherited]`

| Internal method called to notify the object that it has been moved. Reimplemented in Ogre::Light.

void Ogre::ManualObject::_updateRenderQueue | ( | RenderQueue * | queue | ) | `[virtual]`

Remarks:
  The engine will call this method when this object is to be rendered. The object must then create one or more Renderable subclass instances which it places on the passed in Queue for rendering.

.

Implements Ogre::MovableObject.

virtual void Ogre::MovableObject::addQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are appended to the existing flags on this object. Definition at line 338 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::addVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setVisibilityFlags, except the flags passed as parameters are appended to the existing flags on this object. Definition at line 366 of file OgreMovableObject.h.

virtual void Ogre::ManualObject::begin | ( | const String & | materialName,
|  | RenderOperation::OperationType | opType = `RenderOperation::OT_TRIANGLE_LIST`
| ) | `[virtual]`

Start defining a part of the object.

Remarks:
  Each time you call this method, you start a new section of the object with its own material and potentially its own type of rendering operation (triangles, points or lines for example).

Parameters:

  | materialName | The name of the material to render this part of the object with.
  | opType | The type of operation to use to render.

virtual void Ogre::ManualObject::beginUpdate | ( | size_t | sectionIndex | ) | `[virtual]`

Start the definition of an update to a part of the object.

Remarks:
  Using this method, you can update an existing section of the object efficiently. You do not have the option of changing the operation type obviously, since it must match the one that was used before.

Note:
  If your sections are changing size, particularly growing, use estimateVertexCount and estimateIndexCount to pre-size the buffers a little larger than the initial needs to avoid buffer reconstruction.

Parameters:

  | sectionIndex | The index of the section you want to update. The first call to begin() would have created section 0, the second section 1, etc.

class virtual void Ogre::ManualObject::clear | ( | void |  | ) | `[virtual]`

Completely clear the contents of the object.

Remarks:
  Clearing the contents of this object and rebuilding from scratch is not the optimal way to manage dynamic vertex data, since the buffers are recreated. If you want to keep the same structure but update the content within that structure, use beginUpdate() instead of clear() begin(). However if you do want to modify the structure from time to time you can do so by clearing and re-specifying the data.

virtual void Ogre::ManualObject::colour | ( | Real | r,
|  | Real | g,
|  | Real | b,
|  | Real | a = `1.0f`
| ) | `[virtual]`

Add a vertex colour to a vertex.

Parameters:

virtual MeshPtr Ogre::ManualObject::convertToMesh | ( | const String & | meshName,
|  | const String & | groupName = `ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME`
| ) | `[virtual]`

Convert this object to a Mesh.

Remarks:
  After you've finished building this object, you may convert it to a Mesh if you want in order to be able to create many instances of it in the world (via Entity). This is optional, since this instance can be directly attached to a SceneNode itself, but of course only one instance of it can exist that way.

Note:
  Only objects which use indexed geometry may be converted to a mesh.

Parameters:

  | meshName | The name to give the mesh
  | groupName | The resource group to create the mesh in

virtual void Ogre::ManualObject::copyTempVertexToBuffer | ( | void |  | ) | `[protected, virtual]`

| Copy current temp vertex into buffer.

virtual AnimableValuePtr Ogre::AnimableObject::createAnimableValue | ( | const String & | valueName | ) | `[virtual, inherited]`

Create a reference-counted AnimableValuePtr for the named value.

Remarks:
  You can use the returned object to animate a value on this object, using AnimationTrack. Subclasses must override this if they wish to support animation of their values.

virtual void Ogre::ManualObject::estimateIndexCount | ( | size_t | icount | ) | `[virtual]`

Estimate the number of indices ahead of time.

Remarks:
  Calling this helps to avoid memory reallocation when you define indices. Also very handy when using beginUpdate() to manage dynamic data - you can make the index buffer a little larger than the initial need to allow for growth later with this method.

virtual void Ogre::ManualObject::estimateVertexCount | ( | size_t | vcount | ) | `[virtual]`

Estimate the number of vertices ahead of time.

Remarks:
  Calling this helps to avoid memory reallocation when you define vertices. Also very handy when using beginUpdate() to manage dynamic data - you can make the vertex buffers a little larger than their initial needs to allow for growth later with this method.

virtual void Ogre::ShadowCaster::extrudeBounds | ( | AxisAlignedBox & | box,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | const`[protected, virtual, inherited]`

Utility method for extruding a bounding box.

Parameters:

  | box | Original bounding box, will be updated in-place
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

static void Ogre::ShadowCaster::extrudeVertices | ( | const HardwareVertexBufferSharedPtr & | vertexBuffer,
|  | size_t | originalVertexCount,
|  | const Vector4 & | lightPos,
|  | Real | extrudeDist
| ) | `[static, inherited]`

Utility method for extruding vertices based on a light.

Remarks:
  Unfortunately, because D3D cannot handle homogenous (4D) position coordinates in the fixed-function pipeline (GL can, but we have to be cross-API), when we extrude in software we cannot extrude to infinity the way we do in the vertex program (by setting w to 0.0f). Therefore we extrude by a fixed distance, which may cause some problems with larger scenes. Luckily better hardware (ie vertex programs) can fix this.

Parameters:

  | vertexBuffer | The vertex buffer containing ONLY xyz position values, which must be originalVertexCount * 2 * 3 floats long.
  | originalVertexCount | The count of the original number of vertices, ie the number in the mesh, not counting the doubling which has already been done (by VertexData::prepareForShadowVolume) to provide the extruded area of the buffer.
  | lightPos | 4D light position in object space, when w=0.0f this represents a directional light
  | extrudeDist | The distance to extrude

Parameters:

  | edgeData | The edge information to use
  | indexBuffer | The buffer into which to write data into; current contents are assumed to be discardable.
  | light | The light, mainly for type info as silhouette calculations should already have been done in updateEdgeListLightFacing

| Retrieves the number of ManualObjectSection objects making up this ManualObject.

virtual Node* Ogre::MovableObject::getParentNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. Both are Node subclasses so this method will return either.

virtual SceneNode* Ogre::MovableObject::getParentSceneNode | ( | void |  | ) | const`[virtual, inherited]`

Returns the scene node to which this object is attached.

Remarks:
  A MovableObject may be attached to either a SceneNode or to a TagPoint, the latter case if it's attached to a bone on an animated entity. This method will return the scene node of the parent entity if the latter is true.

| Implement this method to enable stencil shadows. Reimplemented from Ogre::MovableObject.

virtual uint32 Ogre::MovableObject::getTypeFlags | ( | void |  | ) | const`[virtual, inherited]`

Get the 'type flags' for this MovableObject.

Remarks:
  A type flag identifies the type of the MovableObject as a bitpattern. This is used for categorical inclusion / exclusion in SceneQuery objects. By default, this method returns all ones for objects not created by a MovableObjectFactory (hence always including them); otherwise it returns the value assigned to the MovableObjectFactory. Custom objects which don't use MovableObjectFactory will need to override this if they want to be included in queries.

Reimplemented in Ogre::BillboardSet, Ogre::Entity, Ogre::Light, Ogre::ParticleSystem, and Ogre::StaticGeometry::Region.

bool Ogre::ManualObject::getUseIdentityProjection | ( | void |  | ) | const

Returns whether or not to use an 'identity' projection.

Remarks:
  Usually ManualObjects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normally you don't need to change this.

See also:
  ManualObject::setUseIdentityProjection

Definition at line 298 of file OgreManualObject.h.

bool Ogre::ManualObject::getUseIdentityView | ( | void |  | ) | const

Returns whether or not to use an 'identity' view.

Remarks:
  Usually ManualObjects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normally you don't need to change this.

| Overridden member from ShadowCaster. Reimplemented from Ogre::MovableObject.

virtual void Ogre::ManualObject::index | ( | uint16 | idx | ) | `[virtual]`

Add a vertex index to construct faces / lines / points via indexing rather than just by a simple list of vertices.

Remarks:
  You will have to call this 3 times for each face for a triangle list, or use the alternative 3-parameter version. Other operation types require different numbers of indexes,

See also:
  RenderOperation::OperationType.

Note:
  32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

  | idx | A vertex index from 0 to 65535.

virtual void Ogre::AnimableObject::initialiseAnimableDictionary | ( | StringVector & |  | ) | const`[protected, virtual, inherited]`

| Internal method for initialising dictionary; should be implemented by subclasses wanting to expose animable parameters. Reimplemented in Ogre::Light. Definition at line 252 of file OgreAnimable.h.

virtual bool Ogre::MovableObject::isAttached | ( | void |  | ) | const`[virtual, inherited]`

| Returns true if this object is attached to a SceneNode or TagPoint.

virtual bool Ogre::MovableObject::isInScene | ( | void |  | ) | const`[virtual, inherited]`

| Returns true if this object is attached to a SceneNode or TagPoint, and this SceneNode / TagPoint is currently in an active part of the scene graph.

virtual bool Ogre::MovableObject::isVisible | ( | void |  | ) | const`[virtual, inherited]`

Returns whether or not this object is supposed to be visible or not.

Remarks:
  Takes into account both upper rendering distance and visible flag.

Reimplemented in Ogre::InstancedGeometry::BatchInstance, and Ogre::StaticGeometry::Region.

virtual void Ogre::ManualObject::normal | ( | Real | x,
|  | Real | y,
|  | Real | z
| ) | `[virtual]`

Remarks:
  Vertex normals are most often used for dynamic lighting, and their components should be normalised.

virtual void Ogre::ManualObject::normal | ( | const Vector3 & | norm | ) | `[virtual]`

Add a vertex normal to the current vertex.

Remarks:
  Vertex normals are most often used for dynamic lighting, and their components should be normalised.

virtual void Ogre::ManualObject::position | ( | Real | x,
|  | Real | y,
|  | Real | z
| ) | `[virtual]`

Remarks:
  A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void Ogre::ManualObject::position | ( | const Vector3 & | pos | ) | `[virtual]`

Add a vertex position, starting a new vertex at the same time.

Remarks:
  A vertex position is slightly special among the other vertex data methods like normal() and textureCoord(), since calling it indicates the start of a new vertex. All other vertex data methods you call after this are assumed to be adding more information (like normals or texture coordinates) to the last vertex started with position().

virtual void Ogre::ManualObject::quad | ( | uint16 | i1,
|  | uint16 | i2,
|  | uint16 | i3,
|  | uint16 | i4
| ) | `[virtual]`

Add a set of 4 vertex indices to construct a quad (out of 2 triangles); this is a shortcut to calling index() 6 times, or triangle() twice.

It's only valid for triangle list operations.

Note:
  32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

  | i1,i2,i3 | 3 vertex indices from 0 to 65535 defining a face.

virtual const LightList& Ogre::MovableObject::queryLights | ( | void |  | ) | const`[virtual, inherited]`

Gets a list of lights, ordered relative to how close they are to this movable object.

Remarks:
  By default, this method gives the listener a chance to populate light list first, if there is no listener or Listener::objectQueryLights returns NULL, it'll query the light list from parent entity if it is present, or returns SceneNode::findLights if it has parent scene node, otherwise it just returns an empty list.

  The object internally caches the light list, so it will recalculate it only when object is moved, or lights that affect the frustum have been changed (

See also:
  SceneManager::_getLightsDirtyCounter), but if listener exists, it will be called each time, so the listener should implement their own cache mechanism to optimise performance.

  This method can be useful when implementing Renderable::getLights in case the renderable is a part of the movable.

Returns:
  The list of lights use to lighting this object.

virtual void Ogre::MovableObject::removeQueryFlags | ( | unsigned long | flags | ) | `[virtual, inherited]`

| As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 342 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::removeVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

| As setVisibilityFlags, except the flags passed as parameters are removed from the existing flags on this object. Definition at line 370 of file OgreMovableObject.h.

virtual void Ogre::ManualObject::resetTempAreas | ( | void |  | ) | `[protected, virtual]`

| Delete temp buffers and reset init counts.

virtual void Ogre::ManualObject::resizeTempIndexBufferIfNeeded | ( | size_t | numInds | ) | `[protected, virtual]`

| Resize the temp index buffer?

virtual void Ogre::ManualObject::resizeTempVertexBufferIfNeeded | ( | size_t | numVerts | ) | `[protected, virtual]`

| Resize the temp vertex buffer?

void Ogre::ManualObject::setBoundingBox | ( | const AxisAlignedBox & | box | ) |

Sets the bounding box.

Remarks:
  Call this after having finished creating sections to modify the bounding box. E.g. if you're using ManualObject to create 2D overlays you can call things function to set an infinite bounding box so that the object always stays visible when attached.

See also:
  ManualObject::setUseIdentityProjection, ManualObject::setUseIdentityView, AxisAlignedBox::setInfinite

Definition at line 329 of file OgreManualObject.h.

void Ogre::MovableObject::setCastShadows | ( | bool | enabled | ) | `[inherited]`

Sets whether or not this object will cast shadows.

Remarks:
  This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note:
  This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

Definition at line 440 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultQueryFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default query flags for all future MovableObject instances. Definition at line 349 of file OgreMovableObject.h.

static void Ogre::MovableObject::setDefaultVisibilityFlags | ( | uint32 | flags | ) | `[static, inherited]`

| Set the default visibility flags for all future MovableObject instances. Definition at line 377 of file OgreMovableObject.h.

virtual void Ogre::ManualObject::setDynamic | ( | bool | dyn | ) | `[virtual]`

| Use before defining gometry to indicate that you intend to update the geometry regularly and want the internal structure to reflect that. Definition at line 154 of file OgreManualObject.h.

virtual void Ogre::MovableObject::setListener | ( | Listener * | listener | ) | `[virtual, inherited]`

Sets a listener for this object.

Remarks:
  Note for size and performance reasons only one listener per object is allowed.

Definition at line 388 of file OgreMovableObject.h.

virtual void Ogre::ManualObject::setMaterialName | ( | size_t | subindex,
|  | const String & | name
| ) | `[virtual]`

Alter the material for a subsection of this object after it has been specified.

Remarks:
  You specify the material to use on a section of this object during the call to begin(), however if you want to change the material afterwards you can do so by calling this method.

Parameters:

  | subIndex | The index of the subsection to alter
  | name | The name of the new material to use

virtual void Ogre::MovableObject::setQueryFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the query flags for this object.

Remarks:
  When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

Definition at line 334 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderingDistance | ( | Real | dist | ) | `[virtual, inherited]`

Sets the distance at which the object is no longer rendered.

Parameters:

  | dist | Distance beyond which the object will not be rendered (the default is 0, which means objects are always rendered).

Definition at line 272 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setRenderQueueGroup | ( | uint8 | queueID | ) | `[virtual, inherited]`

Sets the render queue group this entity will be rendered through.

Remarks:
  Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

  See RenderQueue for more details.

Parameters:

  | queueID | Enumerated value of the queue group to use.

Reimplemented in Ogre::Entity, and Ogre::ParticleSystem.

void Ogre::ManualObject::setUseIdentityProjection | ( | bool | useIdentityProjection | ) |

Sets whether or not to use an 'identity' projection.

Remarks:
  Usually ManualObjects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normally you don't need to change this. The default is false.

See also:
  ManualObject::getUseIdentityProjection

void Ogre::ManualObject::setUseIdentityView | ( | bool | useIdentityView | ) |

Sets whether or not to use an 'identity' view.

Remarks:
  Usually ManualObjects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normally you don't need to change this. The default is false.

See also:
  ManualObject::getUseIdentityView

virtual void Ogre::MovableObject::setUserAny | ( | const Any & | anything | ) | `[virtual, inherited]`

Sets any kind of user value on this object.

Remarks:
  This method allows you to associate any user value you like with this MovableObject. This can be a pointer back to one of your own classes for instance.

Note:
  This value is shared with setUserObject so don't use both!

Definition at line 302 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setUserObject | ( | UserDefinedObject * | obj | ) | `[virtual, inherited]`

Call this to associate your own custom user object instance with this MovableObject.

Remarks:
  By simply making your game / application object a subclass of UserDefinedObject, you can establish a link between an OGRE instance of MovableObject and your own application classes. Call this method to establish the link.

Definition at line 286 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisibilityFlags | ( | uint32 | flags | ) | `[virtual, inherited]`

Sets the visiblity flags for this object.

Remarks:
  As well as a simple true/false value for visibility (as seen in setVisible), you can also set visiblity flags which when 'and'ed with the SceneManager's visibility mask can also make an object invisible.

Definition at line 362 of file OgreMovableObject.h.

virtual void Ogre::MovableObject::setVisible | ( | bool | visible | ) | `[virtual, inherited]`

Tells this object whether to be visible or not, if it has a renderable component.

Note:
  An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visbility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visbility changes are best done using this method; large or more longer term changes are best done by detaching.

Reimplemented in Ogre::Light.

virtual void Ogre::ManualObject::textureCoord | ( | const Vector3 & | uvw | ) | `[virtual]`

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord | ( | const Vector2 & | uv | ) | `[virtual]`

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord | ( | Real | u,
|  | Real | v,
|  | Real | w
| ) | `[virtual]`

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord | ( | Real | u,
|  | Real | v
| ) | `[virtual]`

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::textureCoord | ( | Real | u | ) | `[virtual]`

Add a texture coordinate to the current vertex.

Remarks:
  You can call this method multiple times between position() calls to add multiple texture coordinates to a vertex. Each one can have between 1 and 3 dimensions, depending on your needs, although 2 is most common. There are several versions of this method for the variations in number of dimensions.

virtual void Ogre::ManualObject::triangle | ( | uint16 | i1,
|  | uint16 | i2,
|  | uint16 | i3
| ) | `[virtual]`

Add a set of 3 vertex indices to construct a triangle; this is a shortcut to calling index() 3 times.

It is only valid for triangle lists.

Note:
  32-bit indexes are not supported on all cards which is why this class only allows 16-bit indexes, for simplicity and ease of use.

Parameters:

  | i1,i2,i3 | 3 vertex indices from 0 to 65535 defining a face.

virtual void Ogre::ShadowCaster::updateEdgeListLightFacing | ( | EdgeData * | edgeData,
|  | const Vector4 & | lightPos
| ) | `[protected, virtual, inherited]`

Tells the caster to perform the tasks necessary to update the edge data's light listing.

Can be overridden if the subclass needs to do additional things.

Parameters:

  | edgeData | The edge information to update
  | lightPos | 4D vector representing the light, a directional light has w=0.0
