Resizing an object

[java3d-interest]

How do you resize an object like a Sphere?  I know there is probably some type of transform involved but I haven't been able to figure it out.  I'm new to Java3D and 3D in general so any help would be greatly appreciated.

Hi,

Attach your Shape3D to a TransformGroup, then set a Transform3D instance.
Transform3D is the  object where you can perform several transforms as scale, move, rotate, etc.



See the Java3D Tutorials : http://java.sun.com/developer/onlineTraining/java3d/

Your scene graph will look like this:
[code]
TransformGroup ->Shape3D
     |
     |---> Transform3D
[/code]

So do I just use the setScale method?  I've firgure the zoom, rotate and those, just haven't figured out the scale yet.

[code]
public final void setScale(Vector3d scale)
[/code]

"scale" is a Vector where you set amount of scaling in x, y and z axis.

To uniform scale up by 100%,  do this:

[code]
Vector3d scale = new Vector3d();
scale.x = 2.0d;
scale.y = 2.0d;
scale.z = 2.0d;

myTransform3D.setScale(scale)

myTransformGroup.setTransform(myTransform3D);
[/code]

You can set diferent values to X, Y and Z to have a non-uniform scale efect.
