Hello,
I am currently using RotationPathInterpolator to animate virtual human.
I first build each part of the human body e.g. legs, arms etc. and then
use transformgroup(mainly translations) to form a articulated figure.
However, when I use RotationPath Interpolator to animate the motion of
each part of the body. It seems that the rotation centre is changing.
For example, to animate the right arm, I use the following code
// using RotationPathInterpolator to animate the motion of right arm
// right arm translation - raTrans - to form a figure hirarchy
Transform3D raTrans = new Transform3D();
raTrans.set(new Vector3f(-0.16295f, 0.29f, -0.0183f));
// right arm transformgroup
TransformGroup rShoulderTGT = new TransformGroup(raTrans);
rShoulderTGT.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
upperBodyTGTTemp.addChild(rShoulderTGT);
// right arm rotation behavior
rShoulderTGT.addChild( RotPathBehavior(alpha, rShoulderTGT, raTrans,
rShoulderRIBSKnots, rShoulderRIBSQuatfloat) );
rShoulderTGT.addChild(new HumanRUppArm());
The above code does not work correctly. I think the problem is relevant
to the translation and the specification of the axis of the rotation.
Can anybody point out the problems and give the solution?
I am, in particular, not sure how to specify the Transform axisOfRot in
the constructor of RotationPathInterpolater. any idea on how it should
be done?
Yours sincerely
liming
