Member Function Documentation

void ddgVector3::vectortoangle (void) [inline]

Convert this vector to yaw, pitch, roll angles in degrees.

QUAKE II UNTESTED: See angletovector, problably needs correction for Left Handed coords sys.

void ddgVector3::angletovector (ddgVector3 * forward, ddgVector3 * right = 0, ddgVector3 * up = 0) [inline]

Convert angles of this to vectors for forward, right and up.

Any of the output vectors are optional. Quake II q_shared (73) For Q Right All angles at 0 looks down the X axis. Y is left. Z is up. Right handed system. All angles at 0 looks down the -Z axis. X is right. Y is up. Left handed system.

void ddgVector3::refract (const ddgVector3 * n, float eta) [inline]

Refrect a vector w.r.t.

a normal and a relative index of refraction. eta is the ratio of the index of refraction inthe volume containing the indicent vector to that of the volume being entered. This vector is computed using Snell's law. UNTESTED: Renderman spec.
