OpenGL extension NV.texture_expand_normal
This module customises the behaviour of the
OpenGL.raw.GL.NV.texture_expand_normal to provide a more
Python-friendly API
Overview (from the spec)
This extension provides a remapping mode where unsigned texture
components (in the range [0,1]) can be treated as though they
contained signed data (in the range [-1,+1]). This allows
applications to easily encode signed data into unsigned texture
formats.
The functionality of this extension is nearly identical to the
EXPAND_NORMAL_NV remapping mode provided in the NV_register_combiners
extension, although it applies even if register combiners are used.
The official definition of this extension is available here:
