[osg-users] Jittering/Flickering geometry problem

[umesh ramesh]

Hello Robert,

I created geometries mathematically for a very long road (>1500km). The vertex values are similar to as shown below, for example:
	osg::Vec3d bottom_left(-2849337.167, 42249.143, -1.0);
	osg::Vec3d bottom_right(-2849337.167, 42249.143, -1.0);
	osg::Vec3d top_right(-2849337.167, 42249.143, -1.0);
    	osg::Vec3d top_left(-2849337.167, 42249.143, 1.0);
As you can see, they are high values. 
The problem is the geometry is jittering during animation. I do not want to create the geometries at origin, & translate to the far location. 
How to solve this jittering/Flickering geometry problem in OSG? Any osg::Camera settings we can modify to solve it?

Thank you!..as always to reply to queries.

Cheers,
umesh
