| '''OpenGL extension ARB.half_float_vertex |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ARB.half_float_vertex to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| This extension extends the usage of the half-precision (16-bit) floating- |
| point quantities introduced in ARB_half_float_pixel for usage in specifying |
| vertex array data. |
| |
| This extension allows applications to use half-precision floating point data |
| when specifying vertices. This can allow applications to reduce their |
| memory footprint, as well as the memory bandwidth required for vertex data. |
| |
| This extension extends the existing vertex array commands to accept the new |
| data type. |
| |
| |
| The official definition of this extension is available here: |
