    00033 OgreExternalTextureSource.h  -
    00034     Base class that texture plugins need to derive from. This provides the hooks
    00035     neccessary for a plugin developer to easily extend the functionality of dynamic textures.
    00036     It makes creation/destruction of dynamic textures more streamlined. While the plugin
    00037     will need to talk with Ogre for the actual modification of textures, this class allows
    00038     easy integration with Ogre apps. Material script files can be used to aid in the
    00039     creation of dynamic textures. Functionality can be added that is not defined here
    00040     through the use of the base dictionary. For an exmaple of how to use this class and the
    00041     string interface see ffmpegVideoPlugIn.
