Hi Andy, Actually thats a huge task and the current project does not have that in scope. Do you know any good NURBS facetter available which supports TRIMMED NURBS faceting. I am using Parasolid Library for that purpose right now, but its as heavy as 14MB ! Thanks a lot for your reply.

Hi Daniel, I saw the Graphics Gems online sample code. But unfortunately its too trivial to be used in a product that we are developing and moreover I need TRIMMED NURBS surfaces, and that makes things more complicated. I may try to find out a readymade NURBS facetter instead. Anyways,

Anirban, I agree that there would substantial work involved in writing a comprehensive NURBS library, but a limited library with NURBS curve/surface creation and simple editing could be achieved fairly rapidly. (Correct me if Im wrong, but the OGL does not support advanced NURBS

[JAVA3D] PickResult on Shape3D with multiple geometry

The doc for PickResult says "If the Shape3D being picked has multiple geometry arrays, the arrays are stored in the PickResult and referred to by a geometry index. " It sounds like there's some index that points to which geometry of the Shape3D was picked. How do I get this index? Daniel

There are still some restrictions, Andrew. With multiple geometries, they must all be of the same sub class. For instance you can't have a PointArray and an IndexedGeometryArray on the same Shape3D. You'll see when you read the API. Chris -Original Message- From: Andrew R.
