[osg-users] NodeTrackerManipulator precision ( [Was] Math problem relative to OSG)

2008-12-05 Thread Vincent Bourdier
Hi, Using a nodeTrackerManipulator to make some tests, I think I get some bug in precision... I set the tracked node with a PAT. Each frame, this PAT is modified with two Quat and one translation. Each Quat one is a different rotation... they are added (Q = q1 * q2) and applied to the PAT. The

Hi Vincent, The Quat is stored as doubles, as should the rest of the internal variables in NodeTracker. Which version of the OSG are you using? Older versions didn't use double maths. Robert. On Fri, Dec 5, 2008 at 10:51 AM, Vincent Bourdier [EMAIL PROTECTED] wrote: Hi, Using a

Hi Vincent, When I set the PAT as Tracked node... is PAT is rotated and translated... camera do not follow it... Does your PAT have geometry under it? Or is it just a PAT in space without any children? We had a problem like that before, where if a transform (for us it was an

Hi, It is not a PAT children problem... I'll have a look one day on reproducing the problem... but for now it is not a priority. Thanks for your help, and thanks a lot to everyone here, I've been very intrusive this week, sorry for that. Regards, Vincent. 2008/12/5 Jean-Sébastien Guay
