Hello,everyone!
I've used the OSG in my project for one week.And I found it is powerful,and
it's cool.
My project is a 3D GIS system,I want to make the manipulator like google
earth(GE).So I used the trackballmanipulator.But it has some difference with
GE.When I look the source code of trackballmanipulator,I do not understand the
meaning of trackball function!
Can anyone tell me the meaning of the function?
Waiting for your answers,thank you very much!
Good luck!
