Is there a way to get rust-gpu to work with nalgebra types?

[marstaik]

Hey guys, I love the idea of the project. My question is if its possible to replace the glam:: types with those from nalgebra.

I prefer to use more mathematically based libraries (and nalgebra has glm-like wrappers too from nalgebra_glm.

It would be amazing if I didn't have to convert to glam::Vec types to pass around data for use on cpu/gpu shaders to minimize dependencies and keep my code paths clean and easy to understand.

I don't fully understand how the glam:: types get converted to SPIR-V, I looked a bit through the code and I couldn't fully find if there is any function/translation mapping going on.

Is this currently possible? Would it be a huge lift to do?

In addition to ergonomics, there are some cpu-side performance benefits of nalgebra on certain operations that are of interest.

I don't see anything about the types themselves that would keep them from being compiled with rust-gpu. Typically the first hurdle is making sure the crate can be compiled as no_std. After that there are certain operations to avoid, such as anything that uses NaN or infinities. The best way to find out is to try it yourself! If you run into any problems please open a ticket here and we'll see what we can do :)
