OpenGL extension SGIS.texture4D
This module customises the behaviour of the
OpenGL.raw.GL.SGIS.texture4D to provide a more
Python-friendly API
Overview (from the spec)
This extension defines 4-dimensional texture mapping. If EXT_subtexture
is supported, this extension also defines a mechanism to redefine a
portion of an existing 4-dimensional texture image. Because
EXT_texture3D is required, this extension utilizes the 3-dimensional
image support defined in by EXT_texture3D as a base for 4-dimensional
image manipulation.
The 4th dimension has an abstract, rather than physical, reference
and will be called "extent", since the definition of extent is "that which
specifies the range or magnitude of an area or volume."
Four-dimensional texture mapping is more constrained than its one, two,
and three-dimensional counterparts. Mipmapping is not supported, so
only the level-zero 4-dimensional texture image can be defined. Cubic
filtering is not supported, so the border width must be either zero or
one.
Four-dimensional textures are used primarily as color lookup tables for
color conversion.
