Currently, it seems that rustgpu does not support operator overloading (there is no ops module under spirv_std, and none of the examples seem to do this).

This is useful because although linear algebra is the most popular mathematical representation for transformations in computer graphics, it is not the only option.

For example, I currently use projective geometric algebra for skin animations. To do this I need to define a multivector type on the shader that is capable of addition, multiplication, scalar multiplication...

Of course, one can work around the issue by defining methods, but this is less ergonomic than having operators.

Research direction

Start by inspecting the spirv_std area, especially the reported absence of an ops module, and compare the existing examples for operator usage. Done would mean custom shader types can use operators such as addition, multiplication, and scalar multiplication rather than requiring method-based workarounds.
