Re: [osg-users] setHeight in DriveManipulator
Hi Robert, but isn't it correct that the height only effects the calculation if s.th is hit ? (DriveManipulator.cpp: if (!hitList.empty())...) when I set drive-setIntersectTraversalMask(0x0); (or is this wrong? - I would like to remove the collsion test) - nothing happens when I use setHeight(); if I remove this, it works like I expect Thanks Dieter -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Robert Osfield Sent: Monday, 21 April, 2008 10:44 To: OpenSceneGraph Users Subject: Re: [osg-users] setHeight in DriveManipulator Hi Dieter, The setHeight should take an effect, the DriveManipulator::calcMovement() contains the code that uses the _height member variable. The next frame event should trigger the manipulator to update its position accordingly. The DriveManipulator::setNode(osg::Node* node) method will currently override the _height value, this will be called if you viewer changes its scene graph. Perhaps this is what is causing problems. If so then try using putenv/setenv to set the OSG_DRIVE_MANIPULATOR_HEIGHT env var to the value you want. Robert.

Re: [osg-users] setHeight in DriveManipulator
Hi Dieter, The whole point of the DriveManipulator is that is terrain following, switch off the intersection codes and it won't work as it's designed too. Perhaps a custom made manipulator is what you need. Robert.

You can control this with an environment variable.
