HandmadeMath.h v1.2.0
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 use HandmadeMath without the CRT, you MUST
#define HMM_SINF MySinF
#define HMM_COSF MyCosF
#define HMM_TANF MyTanF
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MYATan2F
Provide your own implementations of SinF, CosF, TanF, ACosF, ATanF, ATan2F,
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
#define HMM_SQRTF MySqrtF
#define HMM_EXPF MyExpF
#define HMM_LOGF MyLogF
#define HMM_ACOSF MyACosF
#define HMM_ATANF MyATanF
#define HMM_ATAN2F MyATan2F
#define HANDMADE_MATH_IMPLEMENTATION
#define HANDMADE_MATH_CPP_MODE
#include "HandmadeMath.h"
If you do not define all five of these, HandmadeMath.h will use the
versions of these functions that are provided by the CRT.
=============================================================================

use HMM_LengthSquaredVec3, or HANDMADE_MATH_CPP_MODE for function
overloaded version)
