OpenGL.GL.AMD.shader_trinary_minmax

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: http://www.opengl.org/registry/specs/AMD/shader_trinary_minmax.txt
