---|---|
static float[] |
clampWOfRotation(float[] rot)
Returns the given rotation as long as its w component does not
exceed 1; otherwise returns a new copy of the given rotation but
with the copy's w value set to 1.
|
static double[] |
rotationDirectionAndAngle(float[] rot)
Provides the given rotation data as a direction vector
(that is, the 3 direction cosines), together with the angle of
rotation about that vector (in degrees).
|
static void |
setRotation(float[] rdest,
float[] rsrc)
Copies the given source rotation to the given destination one.
|
static void |
setRotation(float[] rdest,
Quaternion qsrc)
Copies the given source quaternion rotation values to the given
destination array.
|
static void |
setScaledTranslation(float[] tdest,
float[] tsrc,
float scale)
Copies the given source translation to the given destination one.
|
static void |
setTranslation(float[] tdest,
float[] tsrc)
Copies the given source translation to the given destination one.
|
static java.lang.String |
stringForTR(int fourcc,
float[] trans,
float[] rot)
Returns a string representation of the given translation and
rotation data.
