83 * A virtual trackball implementation
84 * Written by Gavin Bell for Silicon Graphics, November 1988.
87 * Pass the x and y coordinates of the last and current positions of
88 * the mouse, scaled so they are from (-1.0 ... 1.0).
90 * The resulting rotation is returned as a quaternion rotation in the
94 trackball(float q[4], float p1x, float p1y, float p2x, float p2y);
97 * Given two quaternions, add them together to get a third quaternion.
98 * Adding quaternions to get a compound rotation is analagous to adding
99 * translations to get a compound translation. When incrementally
100 * adding rotations, the first argument here should be the new
102 * rotation, the second and third the total rotation (which will be
103 * over-written with the resulting new total rotation).
106 add_quats(float *q1, float *q2, float *dest);
109 * A useful function, builds a rotation matrix in Matrix based on
113 build_rotmatrix(float m[4][4], float q[4]);
116 * This function computes a quaternion based on an axis (defined by
117 * the given vector) and an angle about which to rotate. The angle is
118 * expressed in radians. The result is put into the third argument.
