Hi All, At the risk of appearing very dense, could I ask for a little help with a problem that I have been banging my head against a wall with for the the past week?
The problem is that I have a position and orientation of an observer described by a position vector, and a vector of euler angles that represent the orientation of the observer. To complicate matters, the coordinate system in operation when this information was created was that of WorldToolKit (WTK) - in fact we were using WTK when creating this information. In this system positive Y is down, and positive Z is in towards the screen, with positive x traversing left to right. Now, I would like to represent the position and direction of view (orientation) in OSG's coordinate space. Now, as I understand it, a rotation of -90 degrees will take a point in OSG space, and represent it in WTK space - and the inverse doing the reverse. Cool. The issue I have is what should happen to the orientation vector. The euler angles were obtained from WTK's quaternion to euler function. I've looked at the order of multiplications that occur in WTK when creating the resultant rotation, yet I still can't seem to get the correct result. So, if anyone out there has experience of mapping from WTK to OSG, specifically in regards to what should happen to rotation angles, and quarternians, I would be most grateful - and perhaps my wall could then be repainted beige instead of red ;-( Many thanks for any help Neil. I am trying to bring this into OSG. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
