That would be useful. You can submit it by simply posting the files to the submission forum. (zip the header/cpp - the forum has a problem with files without an extention). You will need to clean up a few things - like adding explanation comments for docgen for each function declaration - to get past Robert. But I was wondering if it would be better as an extention to TrackBallManipulator? The spherical mode is really just a set of constraints to the regular trackball which you might want to turn on and off. For a CAD app being able to lock and free individual rotation axes is certainly useful.

Re: [osg-users] CAD style rotation
Hi all Thanks Martin for his excellent work on SphericalManipulator. I will be so glad if this can be added to the submission list. But there are a few notes and questions: 1 - you have commented the body of zoomOn function, but it's declaration exits in the class. 2 - I think zoomOn function offers a good and useful functionality. Is it necessary to remove it from the manipulator? 3 - I haven't implemented the setByMatrix function, because I don't need it. But this should be done. 4 - There is an small issue in getInverseMatrix and getMatrix functions. Both compute the matrix even if it hasn't changed from the previous step. Maybe it is better to compute it when needed and just return the computed one otherwise. 5 - The member variable named _dragged is not necessary and can be removed. I use it in my specialized version only.

Re: [osg-users] CAD style rotation
Mojtaba and Martin, I like this manipulator and I think it is worthy of inclusion in OSG. Do you plan on submitting it to the submissions list?

Re: [osg-users] CAD style rotation
Should be bool _horizontalLock; bool _verticalLock; at the bottom of the SphericalManipulator definition.

Re: [osg-users] CAD style rotation
I tried compiling this into the released 2.8 code and it complained about _horizontalLock and _verticalLock not being defined. Which source tree were you compiling against? Cory Martin Beckett wrote: I cleaned up the code a little to fit osg naming. Removed the Visual Studio pre-compiled headers so it will build anywhere Added mouse wheel zoom and the ability to select the mod keys (horizontal and vertical rotate only) programmatically. Can you check out the 'usage' function and note any other features I missed.

Re: [osg-users] CAD style rotation
Yes, I've done this as well, pretty easy to write, just allows you to position the camera in altitude and azimuth while maintaining an up vector. I'd say it's more common in sim apps than CAD apps, though. I see someone else has posted code for this.
