The rendering process in Panda is comprised by four classes and their interactions: GraphicsPipe, GraphicsEngine, GraphicsStateGaurdian, and GraphicsOutput. The following sections will explain the purpose of each of these classes in detail.

Note that the following interfaces are for the advanced user only. If you are writing a simple application that only needs to open a window and perform basic 3-D rendering, there is no need to use any of these interfaces, as the appropriate calls to open a default window are made automatically when you import direct.directbase.DirectStart at the start of your application.
