Methods

void create(unsigned int width, unsigned int height, int nSamples = 1)

Creates a new FB object and the two (RGBA+depth) render buffers.

void createDepthMap(unsigned int width, unsigned int height)

Creates a new depth-only FBO.

void destroy()

Release resources.

FrameBufferBinding bind()

Bind this framebuffer object to the current context.

Returns:

The former binding
