'''OpenGL extension OES.single_precision |
|
|
|
|
|
This module customises the behaviour of the |
|
|
OpenGL.raw.GL.OES.single_precision to provide a more |
|
|
Python-friendly API |
|
|
|
|
|
Overview (from the spec) |
|
|
|
|
|
This extension adds commands with single-precision floating-point |
|
|
parameters corresponding to the commands that only variants that |
|
|
accept double-precision floating-point input. This allows an |
|
|
application to avoid using double-precision floating-point |
|
|
data types. New commands are added with an 'f' prefix. |
|
