If I use structs\unions to simplify the way I code my matrix library will the code actually be slower as a result. Here is a sample of Bas Kunens Code:

union { struct { CVector RotX; float m03; CVector RotY; float m13; CVector RotZ; float m23; union { struct { CVector Pos; }; struct { float x,y,z; }; }; float m33; }; float m4x4[4][4]; float m16[16]; };

I''m starting with his class then modifying it my taste''s. I just need to know if not specifying the index directly and simplifying code will kill me in the long run Many thanks Chris
