cglm Documentation — cglm 0.9.6 documentation

# cglm Documentation

cglm is an optimized 3D math library written in C99 (compatible with C89). It is similar to the original glm library, except cglm is mainly for C.

cglm stores matrices as column-major order but in the future row-major is considered to be supported as optional.
