Hi,
Yes that's one consideration but I also wish to interact with my shapes on
a vertex level. Roughly - each shape type has a getVertex(PickRay) or
similar and a setVertex(Point3d, Vector3d) or similar, to get the vertex
nearest to the ray and then to alter it by the mouse drag amount.
I think this might be a question for the Java3D team though as vertex
manipulation appears to me to have been abstracted away from the user -
there are so many things in the way of doing it nicely or cleanly.
ie - is it the case that when a shape is transformed, by say a standard
pick behaviour, that the transform group gets all the changes and that the
vertex information inside the shape remains constant? If so then I need to
apply the transforms explicitly to the vertices and not to the transform
group.
Basically, I just want to stick a cube on the screen, move it around and
then drag individual points around to change its shape.
Thanks,
Tim.
