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.

Comienza inspeccionando el área spirv_std, especialmente la ausencia notificada de un módulo ops, y compara los ejemplos existentes sobre el uso de operadores. Se considerará terminado cuando los tipos de shader personalizados puedan usar operadores como la suma, la multiplicación y la multiplicación escalar, en lugar de requerir soluciones alternativas basadas en métodos.
