WebGLFramebuffer : Object

WebGLFrameBuffer describes an intermediate offscreen drawing surface. The actual content of the surface is stored in a either a WebGLRenderbuffer or WebGLTexture. WebGLFrameBuffers are created with createFramebuffer(). Use framebufferTexture2D() to associate the framebuffer with a WebGLTexture that can be used in subsequent drawing operations. Use framebufferRenderbuffer() to associate the framebuffer with a WebGLRenderingBuffer if you do not need to draw the offscreen surface since the graphics hardware can optimize the render buffer for that case.
