texture-layer-attachment

Vocabulary

gpu.framebuffers

Class description

This class references a single layer and level of detail of a three-dimensional texture or array texture for use as a 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. Array textures require OpenGL 3.0 or the GL_EXT_texture_array extension.
