2/15/2023 0 Comments Gpu support opengl 4.3 amdThe GLSL code has been tested and verified on: Supports both OpenGL 4.3 core and OpenGL ES 3.1. A standalone CLI for verification and benchmarking.ĭesktop Linux and Windows have been tested and are supported. A serialization interface for storing GLFFT wisdom for later use.Support for FFT "wisdom", a method where GLFFT will find optimal parameters for a particular GPU.Applicable for many different GPUs with many performance oriented knobs to tweak.Support for using Shader Storage Buffer Objects or Textures as inputs and outputs to GLFFT.Support for choosing if input and output to GLFFT is treated as packed FP16 or FP32.1D/2D dual complex-to-complex transforms which pair two complex numbers into a vec4 (useful for working for RGBA data).GLFFT is a well featured single-precision and half-precision (FP16) FFT library designed for The two main ones are Tessendorf's FFT water simulation techniqueĪs well as applying massive convolution filters to images more efficiently. GLFFT is implemented entirely with compute shaders. The target APIs are OpenGL 4.3 core profile and OpenGL ES 3.1. GLFFT is a C++11/OpenGL library for doing the Fast Fourier Transform (FFT) on a GPU in one or two dimensions.
