| '''OpenGL extension ARB.internalformat_query |
| |
| This module customises the behaviour of the |
| OpenGL.raw.GL.ARB.internalformat_query to provide a more |
| Python-friendly API |
| |
| Overview (from the spec) |
| |
| OpenGL 4.1 has a number of queries to indicate the maximum number of |
| samples available for different formats. These give a coarse-grained |
| query mechanism e.g. an implementation can expose different sample |
| counts for integer and floating-point formats, but not for different |
| floating-point formats. There is also no convenient way for the user |
| to determine the granularity of sample counts available, only the |
| maximum. |
| |
| This extension adds a query mechanism that allows the user to |
| determine which sample counts are available for a specific internal |
| format. |
| |
| The official definition of this extension is available here: |
| http://www.opengl.org/registry/specs/ARB/internalformat_query.txt |
