hi, I''ve been looking around and cant find the way to transform a 3D vector - [x, y, z] by a 4x4 matrix (asi DirectX7).... I dont really need code - just how to do it, I find it much easier to understand how rather than to copy/paste it... Could someone give me the basics of taking a 4x4 matrix, putting a vector through it and end up with a translated, scaled, rotated vector?? cheers; Jack;
