zec_math

Just a crappy scalar math lib that I'm using across a few different projects.

Inspired by Sean Barrett's stb libraries: https://github.com/nothings/stb

Usage

Do this:

#define ZEC_MATH_IMPLEMENTATION

before you include this file in one C or C++ file to create the implementation.

It should look like this:

#include ...
#define ZEC_MATH_IMPLEMENTATION
#include "zec_math.h"

Vectors are column-major and we use post-multiplication so to transform a vector you would do M * v
Matrices are layed out in row-major form, so data[1][2] refers to the third element in the second row (A_2,3)
To use the matrices produced by this lib with HLSL youll have to enable row-major storage.
