Class FrameBuffer

java.lang.Object
processing.opengl.FrameBuffer
All Implemented Interfaces:
PConstants
public class FrameBuffer extends Object implements PConstants
Encapsulates a Frame Buffer Object for offscreen rendering. When created with onscreen == true, it represents the normal framebuffer. Needed by the stack mechanism in OPENGL2 to return to onscreen rendering after a sequence of pushFramebuffer calls. It transparently handles the situations when the FBO extension is not available.
