// Class : EggRenderMode
|
|
// Description : This class stores miscellaneous rendering properties
|
|
// that is associated with geometry, and which may be
|
|
// set on the geometry primitive level, on the group
|
|
// above it, or indirectly via a texture. It's intended
|
|
// to be a base class for egg objects that can have
|
|
// these properties set.
|
|
//
|
|
// This class cannot inherit from EggObject, because it
|
|
// causes problems at the EggPolygon level with multiple
|
|
// appearances of the EggObject base class. And making
|
|
// EggObject a virtual base class is just no fun.
