[osg-users] Show part of geometry which intersects a specific area

[Ali Ozdin]

I draw a complex geometry. I am changing the position of that geometry with a nodecallback by giving random position values on the screen. There is no problem until here.

I dont want to show whole geometry to the user. I want to define a rectangle and I want to show only the geometry's specific part inside a rectangle on the screen. In other words, I want to show only geometry's specific part intersects that rectangle.



How can I achieve this?

Thanks,
