OpenGL extension ARB.texture_cube_map_array
This module customises the behaviour of the
OpenGL.raw.GL.ARB.texture_cube_map_array to provide a more
Overview (from the spec)
The GL_EXT_texture_array extension, and subsequently OpenGL 3.0 have
introduced the concept of one- and two-dimensional array textures.
An array texture is an ordered set of images with the same size and
format. Each image in an array texture has a unique level. This
extension expands texture array support to include cube map
A cube map array texture is a 2-dimensional array texture that may
contain many cube map layers. Each cube map layer is a unique cube
map image set. Images in a cube map array have the same size and
format limitations as one- and two-dimensional array textures. A
cube map array texture is specified using TexImage3D in a similar
manner to two-dimensional arrays. Cube map array textures can be
bound to a render targets of a frame buffer object as
two-dimensional arrays are using FramebufferTextureLayer.
When accessed by a programmable shader, a cube map array texture
acts as a single unit. The "s", "t", "r" texture coordinates are
treated as a regular cube map texture fetch. The "q" texture is
treated as an unnormalized floating-point value identifying the
layer of the cube map array texture. Cube map array texture lookups
do not filter between layers.
This extension does not provide for the use of cube map array
textures with fixed-function fragment processing.
