Re: Math_Geometry_3D

Just today I've had time to look at your code. Most of the vector code there is already in Math_Vector. It might be a better approach to add your extra methods to either Math_VectorOp, or you can just use Math_Vector instead of re-implementing in your code. The second approach might be better, as there are many more interesting analytical geometry methods/algorithms that deal with general n-dimensional vectors, and some nice ones that are specialized for 3D vectors. Check Math_Vector (deals w/ 2D, 3D and n-D vectors), as well as the geometry section of MathWorld (http://mathworld.wolfram.com/topics/Geometry.html) and similar.
