3d Lib by deks **+
20 Jan 1998 /code/tutors/math/3dlib.zip (5k)
Simple vector and matrix functions. Useless unless you know what they do, and easier to make than use if you do know. Correct code (and math) at the very least. C/C++

Bezier and Spline by plash of Azure ***
20 Jan 1998 /code/tutors/math/azr_bcrv.zip (94k)
Examples of Bezier patches and B-spline curves. Read a reference on bezier or spline modelling first. The math is not easy nor is it explained by the author. Good reference if you are having troubles getting your own routines to work. C/C++
