    00032 OgreExternalTextureSource.h  -
    00033     Base class that texture plugins need to derive from. This provides the hooks
    00034     necessary for a plugin developer to easily extend the functionality of dynamic textures.
    00035     It makes creation/destruction of dynamic textures more streamlined. While the plugin
    00036     will need to talk with Ogre for the actual modification of textures, this class allows
    00037     easy integration with Ogre apps. Material script files can be used to aid in the
    00038     creation of dynamic textures. Functionality can be added that is not defined here
    00039     through the use of the base dictionary. For an example of how to use this class and the
    00040     string interface see ffmpegVideoPlugIn.
