## README

# mat4.c [![stable](http://badges.github.io/stability-badges/dist/stable.svg)](http://github.com/badges/stability-badges)

Part of a fork of [@toji](http://github.com/toji)'s
[gl-matrix](http://github.com/toji/gl-matrix) in c, split into smaller pieces: this
package contains `glMatrix.mat4`.

## Usage

__main.c__
```c

#include <mat4/type.h>
#include <mat4/create.h>

mat4 m4 = mat4_create();

```

`gcc main.c -o main -Inode_modules/mat4.c/include`

### with cmake

__CMakeLists.txt__
```
cmake_minimum_required(VERSION 3.2)
project (mat4-test)
file(GLOB CMAKE_INCLUDES "node_modules/*/CMakeLists.txt")
include(${CMAKE_INCLUDES})
add_executable(main main.c)
```

## mat4_adjoint(out:mat4, a:mat4)

  Calculates the adjugate of a mat4

## mat4_clone(a:mat4)

  Creates a new mat4 initialized with values from an existing matrix

## mat4_copy(out:mat4, a:mat4)

  Copy the values from one mat4 to another

## mat4_create()

  Creates a new identity mat4

## mat4_determinant(a:mat4)

  Calculates the determinant of a mat4

## mat4_fromQuat(out:mat4, q:quat4)

  Creates a matrix from a quaternion rotation.

## mat4_fromRotationTranslation(out:mat4, q:quat4, v:vec3)

  Creates a matrix from a quaternion rotation and vector translation
  This is equivalent to (but much faster than):
  
```c
  mat4_identity(dest);
  mat4_translate(dest, vec);
  mat4 quatMat = mat4_create();
  quat4_toMat4(quat, quatMat);
  mat4_multiply(dest, quatMat);
```
