Rotate Viewpoint 360 Around Point/Object

[hotshotiguana]

I found this example on the worldviz website:
http://docs.worldviz.com/vizard/exam...iewAnimate.htm

It is very similar to what I am looking for, but is there a way to make the transition between pressing 1-4 smooth, i.e. the center of the pivot object is the axis and the user is making a smooth 360 degree rotation around the center leaving a small radius of space between the camera and the object as the rotation happens?

Also, I keep running into quaternion rotation when I google this topic, but I do not see any examples of setQuad on the Viz website. Is there a good reference to learning what this function can do?

Thanks,
Chris
