Re: [osg-users] Problem with local coordinate!
You have to work out what their current centers are, say the instance center is 10,10,10 then then add a static transform to move these to the origin, -10,-10,-10, then if to want to move these instances around you could simply flatten the object so the transform is applied to the verts etc or add a dynamic transform above the static transfom among other options Gordon __ Gordon Tomlinson Product Manager 3D Email : gtomlinson @ overwatch.textron.com __ (C): (+1) 571-265-2612 (W): (+1) 703-437-7651 Self defence is not a function of learning tricks but is a function of how quickly and intensely one can arouse one's instinct for survival - Master Tambo Tetsura From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tuan Do Sent: Wednesday, September 17, 2008 7:51 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] Problem with local coordinate!
