@CnlPepper I tried to calculate csg oprations by: - Torus + Sphere(right) - Sphere(left) - Box(front) (Copper matrial) - Torus * Cylinder (Glass material) Here is the script I used:...

when checking the docs (https://cython.readthedocs.io/en/latest/src/userguide/special_methods.html), I noticed that parameters of `__mul__` method had been changed. (`__mul__(x, y) `-> `__mul__(self, other)`) This seems to cause the issue. And we should implement...
