GLcompute (aka glc) is a Go library for GPGPU using OpenGL ES 3.1 compute shaders as the backend.
glc/contains the actual librarydemo/contains a short example to get started with glc
glc/buffer.go is the most tricky part ; it uses unsafe and reflect to interface Go's safe slices with OpenGL's unsafe mmap-based GPU memory access.
The rest is basically wrappers for OpenGL objects/functions written with the help of go-gl, plus some helper functions.
