OpenGL extension WIN.phong_shading
This module customises the behaviour of the
OpenGL.raw.GL.WIN.phong_shading to provide a more
Overview (from the spec)
WIN_phong_shading enables rendering Phong shaded primitives using OpenGL.
Phong shading is a well known shading technique documented
in most graphics texts.
As opposed to Gouraud (or smooth) shading, which simply calculates the
normals at the vertices and then interpolates the colors of the pixels,
Phong shading involves interpolating an individual normal for every pixel,
and then applying the shading model to each pixel based on its normal
While Phong shading requires substantially more computation than does
Gouraud shading, the resulting images are more realistic, especially if the
primitives are large.
