[osg-users] Clipping when using a shader

[OpenSceneGraph Users]

Hi,
I am using a simple displacement vertex shader to animate a displacement 
field on a geometry.

I am having an issue where during the animation the geometry is getting 
clipped by the near/far planes that are automatically maintained by OSG - 
obviously OSG knows nothing about the displacements of the shader.

Any suggestions as to solve this issue in the most simple manner. I would 
like to avoid having to maintain my own near/far planes. I was hoping OSG 
had a user-definable "fudge" factor for near/far...

Andrew
