| | '''OpenGL extension SGIX.async_histogram |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.SGIX.async_histogram to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension introduces a new asynchronous mode for histogram |
| | and minmax readbacks. It allows programs to get the contents of a |
| | histogram or minmax table without blocking and to continue issuing |
| | graphics commands during the readback. |
| | |
| | The official definition of this extension is available here: |
| | http://www.opengl.org/registry/specs/SGIX/async_histogram.txt |
