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.

Beginne mit der Untersuchung des Bereichs spirv_std, insbesondere des gemeldeten Fehlens eines ops-Moduls, und vergleiche die vorhandenen Beispiele für die Verwendung von Operatoren. Die Aufgabe wäre erfüllt, wenn benutzerdefinierte Shader-Typen Operatoren wie Addition, Multiplikation und Skalarmultiplikation verwenden können, anstatt Workarounds auf Methodenbasis zu erfordern.
