Handmade Math
A single-file, cross-platform, public domain game math library for C/C++.
To get started, go download the latest release.
| Version | Changes |
|---|---|
| 1.6.0 | Added array subscript operators for vector and matrix types in C++. This is provided as a convenience, but be aware that it may incur an extra function call in unoptimized builds. |
| 1.5.1 | Fixed a bug with uninitialized elements in HMM_LookAt. |
| 1.5.0 | Changed internal structure for better performance and inlining. As a result, HANDMADE_MATH_NO_INLINE has been removed and no longer has any effect. |
| 1.4.0 | Fixed bug when using C mode. SSE'd all vec4 operations. Removed zeroing for better performance. |
| 1.3.0 | Removed need to #define HANDMADE_MATH_CPP_MODE. C++ definitions are now included automatically in C++ environments. |
| 1.2.0 | Added equality functions for HMM_Vec2, HMM_Vec3, and HMM_Vec4, and SSE'd HMM_MultiplyMat4 and HMM_Transpose. |
| 1.1.5 | Added Width and Height to HMM_Vec2, and made it so you can supply your own SqrtF. |
| 1.1.4 | Fixed SSE being included on platforms that don't support it, and fixed divide-by-zero errors when normalizing zero vectors. |
| 1.1.3 | Fixed compile error in C mode |
| 1.1.2 | Fixed invalid HMMDEF's in the function definitions |
| 1.1.1 | Resolved compiler warnings on gcc and g++ |
| 1.1 | Quaternions! |
| 1.0 | Lots of testing |
| 0.7 | Added HMM_Vec2, and HMM_Vec4 versions of HMM_LengthSquared, HMM_Length, and HMM_Normalize. |
| 0.6 | Made HMM_Power faster, Fixed possible efficiency problem with HMM_Normalize, RENAMED HMM_LengthSquareRoot to HMM_LengthSquared, RENAMED HMM_RSqrtF to HMM_RSquareRootF, RENAMED HMM_SqrtF to HMM_SquareRootF, REMOVED Inner function (user should use Dot now), REMOVED HMM_FastInverseSquareRoot function declaration |
| 0.5.2 | Fixed SSE code in HMM_SqrtF and HMM_RSqrtF |
| 0.5.1 | Fixed HMM_Translate producing row-major matrices, ensured column-major order for matrices throughout |
| 0.5 | Added scalar operations on vectors and matrices, added += and -= for hmm_mat4, reconciled headers and implementations, tidied up in general |
| 0.4 | Added SSE Optimized HMM_SqrtF, HMM_RSqrtF, Removed use of C Runtime |
| 0.3 | Added +=,-=, *=, /= for hmm_vec2, hmm_vec3, hmm_vec4 |
| 0.2b | Disabled warning C4201 on MSVC, Added 64bit percision on HMM_PI |
| 0.2a | Prefixed Macros |
| 0.2 | Updated Documentation, Fixed C Compliance, Prefixed all functions, and added better operator overloading |
| 0.1 | Initial Version |
