gpu.framebuffers

Class description
Objects of this class represent user-created framebuffer objects. These framebuffer objects provide an offscreen target for rendering operations and can send rendering output either to textures or to dedicated renderbuffers. A framebuffer consists of a set of one or more color framebuffer-attachments, an optional depth buffer framebuffer-attachment, and an optional stencil buffer framebuffer-attachment.

Notes
User-created framebuffer objects require OpenGL 3.0 or one of the GL_ARB_framebuffer_object or GL_EXT_framebuffer_object extensions.
