Re: [JAVA3D] Behaviors Vs. Timers

Hi More importantly the rendering thread can be 1/2 way through drawing something, you come along and move the object, but it's already drawn some parts (sub nodes maybe), and then it draws the next part in the new position and it all looks fairly horid, when I was using timers instead of behavio

Re: [JAVA3D] Automatically generated BoundingBox

Hi My understanding (although I've not tried it myself) is that if you ask a branchgroup for it's bounds, it will tell you the bounds that includes *everything* inside it. Try it to test it, but I think thats right. Jeremy -- Homepage: http://www.computerbooth.com/ Codepage: http://www.newdawns

Re: [JAVA3D] Automatically generated BoundingBox

Yes thats correct but it returns a BoundingSphere, not a BoundingBox. Le Tue, 7 Oct 2003 08:42:14 +0100, Jeremy Booth <[EMAIL PROTECTED]> a écrit: Hi My understanding (although I've not tried it myself) is that if you ask a branchgroup for it's bounds, it will tell you the bounds that includes *ev

Re: [JAVA3D] removing childs

Title: Message Hi Dafna, You should be able to remove the BranchGroup itself that is the ultimate parent of all of your spheres. So - you are not removing all of the BranchGroup's children, but rather you are removing the BranchGroup. That works fine. (As long as you have set the relevant c

Re: [JAVA3D] removing childs

Hi, I know this problem from J3D 1.2.1. The only solution I found, is, to use an additional BranchGroup which fulfills the condition described by the exception. Le Tue, 7 Oct 2003 15:12:09 +0200, dafna gordon <[EMAIL PROTECTED]> a écrit: Messagei tried doing it. i did: BG.removeAllChildren(); and

[JAVA3D] Picking

Re: [JAVA3D] removing childs

I would highly recommend NOT REMOVING the spheres if you can avoid it.  The reason is because of the POOR garbage collection by Java3Dthis removal and reinsertion will cost you a lot. And I speak from experience because I wrote a program to display a 3D scatterplot using spheres which I woul

Re: [JAVA3D] Java3D is giving NullPointerException while rendering on two Canvas3D

This may be a case of bug 4846822, however that bug was supposed to be fixed in 1.3.1 final. It does still show up in the 1.3.1 beta on Linux. Just a guess from looking at the stack trace. As with all bugs on this list, you need to put together a simple test case and post it. -mike On Tue, 2003-
