OpenGL rendering with CUDA

[sjkelly]

There is a small example here that may be of help:

CuArray + GLMakie

Turns out there was some “scalar indexing” going on, where individual elements of the GPU buffers were being copied to the CPU for processing. By using GLBuffer{Point2f} directly, and using low-level APIs that avoid some of the automatic processing (e.g. center! inspects data to determine limits, lines! does a map to detect invalid vertices) I have a working example that keeps all data on the GPU: function plot(; T=Float32, N=1024, resolution=(800,600)) t = CUDA.rand(T, N) X = CUDA.rand…

This uses GLMakie which is built upon GLFW.
