Optimized OpenGL Mathematics library for C
cglm is an optimized 3D math library written in C99 (compatible with C89). It is based on the OpenGL Shading Language (GLSL) specification and similar to the original glm library except this library is written in C. It uses the same header-only approach like glm but also supports pre-compield function calls
This library is designed to be compatible for programming with OpenGL/Vulkan applications. It uses a column-major layout for matrices.
