| '''OpenGL extension ATI.texture_float |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ATI.texture_float to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension adds texture internal formats with 32 and 16 bit |
| floating-point components. The 32 bit floating-point components |
| are in the standard IEEE float format. The 16 bit floating-point |
| components have 1 sign bit, 5 exponent bits, and 10 mantissa bits. |
| Floating-point components are clamped to the limits of the range |
| representable by their format. |
