//
|
|
// CLASS DESCRIPTION (MPxGlBuffer)
|
|
//
|
|
// MPxGlBuffer allows the user to create OpenGL buffers that Maya
|
|
// can draw into. The base class as is defined will create a hardware
|
|
// accellerated off-screen buffer for use on SGI hardware.
|
|
//
|
|
// To create a custom buffer, derive from this class and override at
|
|
// least the open, close, drawable, and context classes. The customized
|
|
// buffer may also require a constructor and destructor to initialize and
|
|
// free its storage correctly.
|
|
