Highly Optimized Graphics Math (glm) for C
📚 Documentation
Almost all functions (inline versions) and parameters are documented inside the corresponding headers.
Complete documentation: http://cglm.readthedocs.io
📌 Note for previous versions:
- _dup (duplicate) is changed to _copy. For instance
glm_vec_dup -> glm_vec3_copy
- OpenGL related functions are dropped to make this lib platform/third-party independent
- make sure you have latest version and feel free to report bugs, troubles
- [bugfix] euler angles was implemented in reverse order (extrinsic) it was fixed, now they are intrinsic. Make sure that
you have the latest version
- [major change] by starting v0.4.0, quaternions are stored as [x, y, z, w], it was [w, x, y, z] in v0.3.5 and earlier versions
- [api rename] by starting v0.4.5, glm_simd functions are renamed to glmm_
- [new option] by starting v0.4.5, you can disable alignment requirement, check options in docs.
- [major change] by starting v0.5.0, vec3 functions use glm_vec3_ namespace, it was glm_vec_ until v0.5.0
- [major change] by starting v0.5.1, built-in alignment is removed from vec3 and mat3 types
- [major change] by starting v0.7.3, inline print functions are disabled in release/production mode to eliminate print costs (see options in documentation). Print output also improved. You can disable colors if you need (see documentation)
- [major change] by starting v0.8.3, cglm supports alternative clipspace configuations e.g. Left Handed, Zero-to-One (_zo)...
CGLM_FORCE_DEPTH_ZERO_TO_ONE and CGLM_FORCE_LEFT_HANDED is provided to control clipspace. You should be able to use cglm with Vulkan, DirectX and Metal now... see https://cglm.readthedocs.io/en/latest/opt.html#clipspace-option-s
