There are a couple of projects around making use of the GPU.
In Erlang, there’s a long-running project called Wings3D (http://www.wings3d.com) that uses OpenGL.
The Elixir projects seem mainly to focus on machine-learning. There’s an entry point to that world here: Elixir and Machine Learning: Nx v0.1 released! - Dashbit Blog, OR JIT/GPU accelerated deep learning for Elixir with Axon v0.1 – Sean Moriarity, and some work that predates Nx here: Deep Learning library with GPU(CUDA/cuBLAS)
Good luck with your project!
