Hello,
I am just getting started with Java3D, so I am just trying to do some simple
things with the help of the utility classes (while reading Sun's tutorial),
but I quickly got stuck.
What I tried to do was to rotate two cubes, but I wanted to apply a simple
translation to one of them so that they wouldn't be in the exact same spot.
This translation works as long as I don't rotate the cube, but as soon as I
rotate it it seems to move back to it's original position (0,0,0).
The following code builds the scene graph. I'd appreciate any pointers as to
what I am missing.
Thanks!
BranchGroup objRoot = new BranchGroup();
TransformGroup objSpin1 = new TransformGroup();
objSpin1.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
objRoot.addChild(objSpin1);
objSpin1.addChild(new ColorCube(0.1));
Transform3D translate2 = new Transform3D();
Vector3f vector2 = new Vector3f(0.0f, 0.5f, 0.0f);
translate2.setTranslation(vector2);
TransformGroup objSpin2 = new TransformGroup(translate2);
objSpin2.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
objRoot.addChild(objSpin2);
objSpin2.addChild(new ColorCube(0.1));
Alpha rotationAlpha = new Alpha(-1, 4000);
RotationInterpolator rotator1 =
new RotationInterpolator(rotationAlpha, objSpin1);
RotationInterpolator rotator2 =
new RotationInterpolator(rotationAlpha, objSpin2);
BoundingSphere bounds = new BoundingSphere();
rotator1.setSchedulingBounds(bounds);
rotator2.setSchedulingBounds(bounds);
objSpin1.addChild(rotator1);
objSpin2.addChild(rotator2);
