NAME

7       ming library.

SYNOPSIS

13       void apply_quat(const QUAT *q, float x, y, z, *xout, *yout, *zout);

DESCRIPTION

16       Multiplies the point (x, y, z) by the quaternion q, storing the  result
17       in   (*xout,   *yout,   *zout).   This  is  quite  a  bit  slower  than
18       apply_matrix_f(), so only use it to translate a few points. If you have
19       many  points,  it  is  much more efficient to call quat_to_matrix() and
20       then use apply_matrix_f().
