Highly optimized 2D|3D math library, also known as OpenGL Mathematics (glm) for `C`. cglm provides lot of utils to help math operations to be fast and quick to write. It is community-friendly, feel free to bring any issues, bugs you faced. Almost all functions (inline versions) and parameters are documented inside the corresponding headers. OpenGL-related functions are dropped to make this lib platform/third-party independent. Make sure you have the latest version and feel free to report bugs, troubles. Euler angles was implemented in reverse order (extrinsic) it was fixed, now they are intrinsic. Make sure that you have the latest version. vec4 and mat4 variables must be aligned. (There will be unaligned versions later). cglm doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for out parameters too if you pass pointer of memory location.
Features
- cglm supports both ARRAY API and STRUCT API
- Like some other graphics libraries (especially OpenGL) this library use Column-Major layout to keep matrices in the memory
- Scalar and simd (sse, avx, neon...) optimizations
- Option to use different clipspaces e.g. Left Handed, Zero-to-One... (currrently right handed negative-one is default)
- Array api and struct api, you can use arrays or structs
- General purpose vector operations (cross, dot, rotate, proj, angle...)
- Matrix decomposition (extract rotation, scaling factor)
