| '''OpenGL extension SGIX.shadow_ambient |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.SGIX.shadow_ambient to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension allows a value other than 0.0 to be returned by the |
| SGIX_shadow operation in the case when the shadow test passes. |
| With this extension any floating point value in the range [0.0, |
| 1.0] can be returned as the texture value when an object is in |
| shadow. This allows the (untextured) ambient lighting and direct |
| shadowed lighting from a single light source to be computed in a |
| single pass. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/SGIX/shadow_ambient.txt |
