you can invert a Matrix with "__invert__()" or the Python "invert" operator "~" .
inverseMatrix = ~worldSpaceCoords
You may also take a look at the GeRayCollider that can be used to calculate the intersections of a ray and a poly object.
Yes, but that is all for a cinema 4d matrix and that is a 4x4 matrix, not a 3x3 matrix.
I want to use a 3x3 matrix.
I know I can use the GeRayCollider, but I want to do it myself.
So, how to do 3x3 matrix calculations in cinema 4d?
