| | '''OpenGL extension NV.light_max_exponent |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.NV.light_max_exponent to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | Default OpenGL does not permit a shininess or spot exponent over |
| | 128.0. This extension permits implementations to support and |
| | advertise a maximum shininess and spot exponent beyond 128.0. |
| | |
| | Note that extremely high exponents for shininess and/or spot light |
| | cutoff will require sufficiently high tessellation for acceptable |
| | lighting results. |
| | |
| | Paul Deifenbach's thesis suggests that higher exponents are |
| | necessary to approximate BRDFs with per-vertex ligthing and |
| | multiple passes. |
| | |
| | The official definition of this extension is available here: |
