MPS Support?

[andrewkchan]

Hi! I recently ported OpenSplat's fork of the gsplat library to metal performance shaders so that training splats could use GPUs on Macs. I was wondering if the team would be interested in me upstreaming these changes. I noticed the CUDA kernels are newer than the OpenSplat ones, have some ongoing development, and there may be questions of whether an MPS backend is worth maintaining.

Hi Andrew, I've just started my CUDA/metal journey and am learning fast, I would defo be interested in a metal port. I would also be willing to maintain it. Let me know if you're still interested

Hi @josephldobson, sorry just saw your message. I'm busy with other things these days but my patch adding metal support can be read in this PR if you want to give upstreaming it a shot! pierotofy/OpenSplat#76
