Detailed Description

Represents an OpenGL renderbuffer.

CC3GLRenderbuffer implements the CC3FramebufferAttachment, allowing it to be attached to a framebuffer. This class represents a general off-screen or on-screen GL renderbuffer, whose storage is allocated from GL memory.

Broadly speaking, there are two ways to instantiate an instance and manage the lifespan of the corresponding renderbuffer in the GL engine, these are described as follows.

If you instantiate an instance without explicitly providing the ID of an existing OpenGL renderbuffer, a renderbuffer will automatically be created within the GL engine, as needed, and will automatically be deleted from the GL engine when the instance is deallocated.

To map to an existing OpenGL renderbuffer, you can provide the value of the renderbufferID property during instance instantiation. In this case, the instance will not delete the renderbuffer from the GL engine when the instance is deallocated, and it is up to you to coordinate the lifespan of the instance and the GL renderbuffer. Do not use the instance once you have deleted the renderbuffer from the GL engine.

Method Documentation

- (void) bind

Binds this renderbuffer as the active renderbuffer in the GL engine.

- (instancetype) initWithPixelFormat: (GLenum) format

Initializes this instance with the specified pixel format and with one sample per pixel.
