OpenGL.GL.NV.shader_atomic_float

OpenGL extension NV.shader_atomic_float

This module customises the behaviour of the OpenGL.raw.GL.NV.shader_atomic_float to provide a more Python-friendly API

Overview (from the spec)

This extension provides GLSL built-in functions and assembly opcodes allowing shaders to perform atomic read-modify-write operations to buffer or texture memory with floating-point components. The set of atomic operations provided by this extension is limited to adds and exchanges. Providing atomic add support allows shaders to atomically accumulate the sum of floating-point values into buffer or texture memory across multiple (possibly concurrent) shader invocations.

This extension provides GLSL support for atomics targeting image uniforms (if GLSL 4.20, ARB_shader_image_load_store, or EXT_shader_image_load_store is supported) or floating-point pointers (if NV_gpu_shader5 is supported). Additionally, assembly opcodes for these operations is also provided if NV_gpu_program5 is supported.
