| | '''OpenGL extension AMD.shader_trinary_minmax |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.AMD.shader_trinary_minmax to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | This extension introduces three new trinary built-in functions to the |
| | OpenGL Shading Languages. These functions allow the minimum, maximum |
| | or median of three inputs to be found with a single function call. These |
| | operations may be useful for sorting and filtering operations, for example. |
| | By explicitly performing a trinary operation with a single built-in |
| | function, shader compilers and optimizers may be able to generate better |
| | instruction sequences for perform sorting and other multi-input functions. |
| | |
| | The official definition of this extension is available here: |
