[vtkusers] small objects are not rendered

[Eric Pichon]

Hi All,

When trying to render many objects, VTK will discard those that are too
small and too far (even though they are still much bigger than one pixel).

I understand that this makes sense in many cases but it is a problem for
what I want to do (basically rendering hundreds of small spheres) and I
did not manage to get VTK to render all the actors regardless of any
optimization consideration.

I set manually the clipping planes of the camera and I am not using
vtkLODactors but regular vtkActors.

Your help would be greatly appreciated !

I am using VTK 4.0 on a Sun Ultra 80 (SunOS 5.7 sun4u sparc SUNW)

It was compiled using gcc version 2.95.2.

At startup VTK says :
Using: /usr/openwin/platform/SUNW,Ultra-80/lib/GL/oglSUNWcore.so.4
Using: /usr/openwin/platform/SUNW,Ultra-80/lib/GL/libvis.so.1
