About

libflg (library of FLoyd Geometry) is collection of usefule 2D/3D geometry functions.

Types

libfl includes many useful geometric types, such as:

2D/3D/pseudo-4D points and vectors
lines, planes, cuboids, spheres
rotations, euler angles, quaternions
transformation matrixes
array versions of most primitive types

Functions

The best place to learn about implemented functions is, of course, source. If you are impatient to add new types/functions, please follow the guidelines:

All functions are grouped into header files according to argument & result types. Headers are self-contained - i.e. if you have to use function flg_point3_transform_matrix4, you only have to include header flg-point3-matrix4.h.
General function name is flg-{return type}-[{other types}].h
If return type is primitive (eg. FLGFloat), function name is taken from first structure argument type.
If function has several arguments of same type, their names are usually not repeated
