Thanks rob! I did manage to get something working using PickRays as well. Using the getDistance call on the PickIntersection I can check the collision point against my own end point and make it all operate like a PickSegment. Also, I can't seem to getPointNormal() or getPrimitiveNormals() to work reliably. Sometimes it works and sometimes it doesn't. And I KNOW there are normals in there! :-) Has anyone else had any trouble with that? Thanks again. >From: Rob Nugent <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: Shawn Kendall <[EMAIL PROTECTED]> >CC: [EMAIL PROTECTED], [EMAIL PROTECTED] >Subject: Re: PickSegment woes with 1.2 beta1 (WinNT) >Date: Mon, 31 Jan 2000 10:25:14 +0000 > >Shawn > >From what Chien Yang and Doug Gehringer have told me there is at least one >PickSegment bug that they have now fixed and will (presumably) be in the >next >Java 3D beta. > >In the meantime I've managed to make PickRays do what I want (at some >performance cost) as a workaround. > >Regards >Rob > >Shawn Kendall wrote: > > > I am having a similiar problem in my app using the PickTool and >segments... > > > > Is anyone else having problems with the PickTool? > > I can get intersections back ONLY when my segment is off axis i.e. >tilted. > > If I use a segment pointing straight down I get NULL PickResults, and > > believe the segment crosses a triangle... > > > > I REALLY need it to work, I can't right any kind of usable navigation > > routine such as terrain following without accurate collision detection! > > > > ______________________________________________________ > > Get Your Private, Free Email at http://www.hotmail.com > >-- > > >Rob Nugent >Development Manager >PeerLogic >[EMAIL PROTECTED] >http://www.peerlogic.com >http://www.unikix.com >Tel: +44 (0) 1489 585503 >Fax: +44 (0) 1489 881363 > > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
