Vocabulary

gpu.framebuffers

Class description

This class is a union of the texture-1d-attachment, texture-2d-attachment, texture-3d-attachment, and texture-layer-attachment classes, which select layers and levels of detail of texture objects to serve as framebuffer attachments.

Notes

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