HandmadeMath.h v0.7
HandmadeMath.h v1.0
This is a single header file with a bunch of useful functions for
basic game math operations.
==========================================================================
You MUST
#define HANDMADE_MATH_IMPLEMENTATION
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_IMPLEMENTATION
#include "HandmadeMath.h"
All other files should just #include "HandmadeMath.h" without the #define.
==========================================================================
For overloaded and operator overloaded versions of the base C functions,
you MUST
#define HANDMADE_MATH_CPP_MODE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#include "HandmadeMath.h"
All other files should just #include "HandmadeMath.h" without the #define.
==========================================================================
To disable SSE intrinsics, you MUST
#define HANDMADE_MATH_NO_SSE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#define HANDMADE_MATH_NO_SSE
#include "HandmadeMath.h"
or
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_NO_SSE
#include "HandmadeMath.h"
==========================================================================
To disable inlining functions, you MUST
#define HANDMADE_MATH_NO_INLINE
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#define HANDMADE_MATH_NO_INLINE
#include "HandmadeMath.h"
All other files should just #include "HandmadeMath.h" without the #define.
==========================================================================
To Disable the CRT, you MUST
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
Provide your own implementations of SinF, CosF, TanF, ExpF and LogF
in EXACTLY one C or C++ file that includes this header, BEFORE the
include, like this:
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF

If you do not define all five of these, HandmadeMath.h will use the
versions of these functions that are provided by the CRT.

----------------|----------------|
**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 |
