Re: [JAVA3D] Geometry Update

[Yazel, David J.]

Ooh this is a good one!   Since it is considered illegal to update the vertices of by-ref geometry outside of a geometry updater it would be "bad" to do as you have suggested.  However, I am not sure if it would actually be a problem if you do this from a behavior since I would expect that both geometry array's would already be winging their way to the card.  But if you wanted to play it safe, try making a dummy updator that does nothing but invoke the other updater on the other geometry array.  This should lock both at the same time.  You could even build a generic class that could manage "shared by-ref geometry" to provide this locking.   Dave Yazel -----Original Message-----    From: Michael Nischt [mailto:[EMAIL PROTECTED]] Sent: Monday, April 01, 2002 1:16 PM To: [EMAIL PROTECTED] Subject: [JAVA3D] Geometry Update hello everyone,   I have an question concerning geometry-update, with shared vertices:   Two (Indexed)GeometryArrays (BY_REFERENCE) share the same vertices (with different indices), because some parts have different Materials. I decided to put the same cordinate/normal arrays in both and I update one with a GeometryUpdater, and  both were updated correct. :-)   But I am wondering if this legal, because the second one has no GeometryUpdater ? do I have to put an dummy updater for the second one ?   greetings -Michael Nischt   btw. a Test application is attached for better understanding
