Summary0000175: camera clipping of parts of my model when zooming in real close
DescriptionI NEED the ability to zoom into tiny features in models. Part of my application's responsiblity is
to find and show those features to the user and fix them.

In vtkRenderer.cxx at about line 868, I find,
range[0] = (range[0] < 0.01*range[1])? ......
The .01 is clipping my model where I don't want it to.

I at least need the ability to specify my own clamping range, to 0.001 or whatever, and have
vtkRenderer.cxx use that value.

 actually... what would be really nice is to know how someone else has done it. I can change my viewing parameters (eg parallel projection) and I can see these small parts fine. I'd like it to work in perspective mode which is our default viewing mode.

 Brad, is this going to be doable with the new renderer pipeline ?

 This has nothing to do with the new pipeline architecture. It is simply a feature of the rendering interface.

 This has been fixed in CVS. (and I am in the midst of cleaning up the fix further) There is now an ivar called NearClippingPlaneTolerance on vtkRenderer that controls how close the near clipping plane is allowed to get relative to the far clipping plane.
