Version | Changes |
----------------|----------------|
**1.10.1** | Removed stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
**1.10.2** | Introduced safe floating point comparrision in HMM_EqualsVec2, HMM_EqualsVec3, HMM_EqualsVec4. |
**1.10.1** | Removed use of stdint.h, this doesn't exist on some really old compilers and we didn't really use it anyways. |
**1.10.0** | Made HMM_Perspective use vertical FOV instead of horizontal FOV for consistency with other graphics APIs. |
**1.9.0** | Added SSE versions of quaternion operations. |
**1.8.0** | Added fast vector normalization routines that use fast inverse square roots.
