# get\_vector\_rotation\_matrix(3alleg)

Constructs X, Y, Z rotation matrices with an angle. Allegro game programming library.

## NAME

get\_vector\_rotation\_matrix, get\_vector\_rotation\_matrix\_f - Constructs X, Y, Z rotation matrices with an angle. Allegro game programming library.

## SYNOPSIS

**#include \<allegro.h\>**

**void get\_vector\_rotation\_matrix(MATRIX \*m, fixed x, y, z, fixed a);**

**void get\_vector\_rotation\_matrix\_f(MATRIX\_f \*m, float x, y, z, float a);**

## DESCRIPTION

Constructs a transformation matrix which will rotate points around the  specified x,y,z vector by the specified angle (given in binary, 256  degrees to a circle format).
