Subject: Re: [JAVA3D] Animating
body
Hi all!
I looked at Alessandro's scenegraph (what he
suggested in his post once) and to main. My body parts all have a TG as
parent.
All body parts classes were created with the
following logic:
public class RightShin extends
TransformGroup{
public
RightShin() {
TransformGroup joint = new
TransformGroup();
TransformGroup leg = new
TransformGroup();
javax.media.j3d.Transform3D t3d1 = new
javax.media.j3d.Transform3D();
javax.media.j3d.Transform3D t3d2 = new
javax.media.j3d.Transform3D();
t3d1.setEuler(new
javax.vecmath.Vector3d(0.0, Math.PI/2.0f, 0.0));
//szög
t3d1.setTranslation(new
javax.vecmath.Vector3d(0.0d,-0.165d,0.0d)); //pozició
setCapability(TransformGroup.ALLOW_TRANSFORM_READ |
TransformGroup.ALLOW_TRANSFORM_WRITE);
setTransform(t3d1);
t3d2.setTranslation(new
javax.vecmath.Vector3d(0.0d,-0.10d,0.0d));
joint.addChild(new Sphere(0.03f,Sphere.GENERATE_TEXTURE_COORDS,new
PAppear("c:/work/texturelibrary/Architectual/limesto3.jpg")));
joint.addChild(leg);
leg.addChild(new Cylinder(0.03f,0.17f,Cylinder.GENERATE_TEXTURE_COORDS,new
PAppear("c:/java.jpg")));
joint.setTransform(t3d2);
addChild(joint);
}
}
I have tried to include a rotationinterpolator in
one of my body classes ex. for the other leg. Here is the code
public class RightLeg extends
TransformGroup{
public
RightLeg(BoundingSphere boundingSphere) {
TransformGroup jointTG =
new TransformGroup();
TransformGroup legTG = new
TransformGroup();
javax.media.j3d.Transform3D jointTransform = new
javax.media.j3d.Transform3D();
javax.media.j3d.Transform3D legTransform = new javax.media.j3d.Transform3D();
jointTransform.setEuler(new javax.vecmath.Vector3d(0.0, Math.PI/2.0f,
0.0));
jointTransform.setTranslation(new
javax.vecmath.Vector3d(0.07d,0.07d,0.0d));
jointTG.addChild(new Sphere(0.03f,Sphere.GENERATE_TEXTURE_COORDS,new
Appear()));
setCapability(TransformGroup.ALLOW_TRANSFORM_READ|TransformGroup.ALLOW_TRANSFORM_WRITE);
setCapability(TransformGroup.ALLOW_CHILDREN_READ);
jointTG.setCapability(TransformGroup.ALLOW_TRANSFORM_READ|TransformGroup.ALLOW_TRANSFORM_WRITE);
jointTG.setTransform(forgoTransform);
legTG.setCapability(TransformGroup.ALLOW_TRANSFORM_READ|TransformGroup.ALLOW_TRANSFORM_WRITE);
legTransform.setEuler(new javax.vecmath.Vector3d(0.0, Math.PI/2.0f, 0.0));
//szög
legTransform.setTranslation(new
javax.vecmath.Vector3d(0.0d,-0.095d,0.0d));
legTG.addChild(new Cylinder(0.03f,0.17f,Cylinder.GENERATE_TEXTURE_COORDS,new
Appear())); //a lab hengere
legTG.setTransform(labTransform);
jointTG.addChild(labTG);
Alpha
alpha = new Alpha(-1,60000);
TransformGroup objSpin = new
TransformGroup();
forgato.setCapability(TransformGroup.ALLOW_TRANSFORM_READ|TransformGroup.ALLOW_TRANSFORM_WRITE);
RotationInterpolator rotInt = new
RotationInterpolator(alpha,objSpin);
rotInt.setSchedulingBounds(boundingSphere);
objSpin.addChild(jointTG);
addChild(jointTG);
addChild(rotInt);
}
}
If i add rotInt as child of the parent TG at
runtime it drops me the following error:
javax.media.j3d.CapabilityNotSetException: Group: no capability to
set transform
at
javax.media.j3d.TransformGroup.setTransform(TransformGroup.java:105)
at
javax.media.j3d.TransformInterpolator.processStimulus(TransformInterpolator.java:156)
at
javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:172)
at
javax.media.j3d.J3dThread.run(J3dThread.java:250)
... without any
error being in my source files. I have set the Capabilities in my TG. I
have set them in all TransformGroups i am using.
Please help me!
What should i do with this?
Bye,
Levi
