gl_renderbuffer Struct Reference

#include <mtypes.h>

---

Detailed Description

A renderbuffer stores colors or depth values or stencil values.

A framebuffer object will have a collection of these. Data are read/written to the buffer with a handful of Get/Put functions.

Instances of this object are allocated with the Driver's NewRenderbuffer hook. Drivers will likely wrap this class inside a driver-specific class to simulate inheritance.
