Re: Scaling of an external TransformGroup

To create your own scene graph depiction, you need to at

CoordinateSystems are involved, you also need to apply
their coordinate transforms.

I strongly suggest building your wire frame as a Gridded3DSet
with manifold dimension = 1.

hi Bill,

i tryed out your suggestion with the Gridded3DSet. The problem is, that what i get is totaly different from what i need. The data have a structure (given by the connecting list), that have to be exactly displayed on the screen. So the question is how to get the scaling from the ScalarMap? I can't find any method to get the scaling. I tryed out the getMatrix() method from the ProjectionControl, but the result is also wrong. Can you explain me how to get the scaling?
