Re: [osg-users] PositionAttitudeTransform uniform scaling
Thank you for the reply, I know it was a dumb question. I hadn't fully understood the inner workings of the setPivotPoint function.

[osg-users] Absolute_Rf to Relative_Rf coordinates
I'm displaying some text in a 3D scene using a transform with an absolute reference frame. I now need to find out what the world coordinates of the text are, is that any way to easily obtain that information? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] makeLookAt and Oculus rift quaternion question
I have 3D scene set up in osg, and I'm trying to use oculus rift to view the scene. What I'm trying to do is calibrating an initial position using makeLookAt and grabbing the rotation in order to focus the camera on a specific spot of the scene; The problem arises when I then attempt to stack the oculus rotation quaternion on top of the makeLookAt rotation, the math eludes me and I cannot seem to get it working correctly. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] World coordinates and meters
Is there any correlation between world coordinates and real-world distance, such as meters? For instance, is the point (1,0,0) located 1 meter in the X axis, and if not, is there any way to correlate the two? I ask this because I'm working with a kinect, and it returns coordinates in meters within the reference frame of the kinect. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgOculusViewer and osg::Text
Thank you for the reply Robert, I have since solved the problem. I was using a 2DOrtho projection using pixel coordinates to set up a layer upon which to render the text and using a matrix transform to set it to an absolute referential, and it interacted weirdly with osgOculusViewer.Removing the 2DOrtho projection and setting up the text on the 3D scene instead solved my problem.

Does the rest of the 3D scene work OK? How you are managing your text and GUI? Do you have transforms above them? Is it a HUD? Is in part of the 3D scene? Robert.
