Hi, I am pretty sure this functionality is not built in to any of the OSG manipulators. I have implemented this functionality in our application which is based on OSG so I can say that it is not that difficult to do. Unfortunately I don't have any useful code to share as all my camera manipulation code is written in Java and uses our own manipulator framework.

I am wondering if it is it possible to perform zooming based on cursor point? osgViewer only zooms taking center of the screen as center point for zooming. I want the zooming center to adapt position of the cursor, like in openlayers and google maps. Is it possible to do this in OSG? or if there is an tricks please help... Thank you!
