Free vector,quaternion,matrix math library
Over 75 C++ function for working with vectors, matrix and quaternions. Inside the package there is no cycles, if's, classes or structures. Ideal for designing 3D engines. Headlines of functions are intuitive. For each headline there is a one line comment in Russian. Matrix are presented in OpenGL form 0 4 8 12 1 5 9 13 2 6 10 14 3 7 11 15 Now we are working on adding 50+ more functions for processing the planes, splines, bezier curves and interpolation methods.
