A Switch Node should do what you want. The Switch node will allow you to add 4 models
and selectively turn models on and off.
This is not the same as dynamically adding objects after the scene is live, for that
you have to set Group capabilities on the Groups where the objects are to be added.
You want the ALLOW_CHILDREN_EXTEND and probably the ALLOW_CHILDREN_READ,
ALLOW_CHILDREN_WRITE capabilities.
> Select wire frame or solid format for a geometry that is already loaded?
For this you want to modify the Appearance NodeComponent for a Shape3D object. The
Shape3D will need the ALLOW_APPEARANCE_READ, ALLOW_APPEARANCE_WRITE capabilities.
// create an appearance
Appearance ap = new Appearance();
// render as a wireframe
PolygonAttributes polyAttrbutes = new PolygonAttributes();
polyAttrbutes.setPolygonMode( PolygonAttributes.POLYGON_LINE );
polyAttrbutes.setCullFace( PolygonAttributes.CULL_NONE ) ;
ap.setPolygonAttributes( polyAttrbutes );
You will beed the ALLOW_MODE_READ, ALLOW_MODE_WRITE, ALLOW_CULL_FACE_READ,
ALLOW_CULL_FACE_WRITE capabilities on the PolygonAtrtributes object you assign to the
Appearance node.
I hope this helps, please respond with any comments as this is from my forthcoming
book on Java 3D, due out around New Year.
Sincerely,
Daniel Selman
