## NAME

get\_align\_matrix - Rotates a matrix to align it along specified coordinate vectors. Allegro game programming library.

## SYNOPSIS

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

**void get\_align\_matrix(MATRIX \*m, fixed xfront, yfront, zfront,** **fixed xup, fixed yup, fixed zup);**

## DESCRIPTION

Rotates a matrix so that it is aligned along the specified coordinate  vectors (they need not be normalized or perpendicular, but the up and  front must not be equal). A front vector of 0,0,-1 and up vector of 0,1,0  will return the identity matrix.
