quat_mul(3alleg4) Allegro manual quat_mul(3alleg4)
NAME
quat_mul - Multiplies two quaternions. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void quat_mul(const QUAT *p, const QUAT *q, QUAT *out);
DESCRIPTION
Multiplies two quaternions, storing the result in out. The resulting quaternion will have the same effect as the combination of p and q,
ie. when applied to a point, (point * out) = ((point * p) * q). Any number of rotations can be concatenated in this way. Note that quater-
nion multiplication is not commutative, ie. quat_mul(p, q) != quat_mul(q, p).
