[vtkusers] Render properties, marching cubes

[Seema Jaisinghani]

Hi,

I am rendering iso-surfaces using marching cubes. I
have got the geometry and converted each surface into
an actor with its color proerties etc. But it does not
seem to be rendering very clearly. Most of it appears
white and shiny, traces of color are seen only in some
portions when the objects are moved around.Is it
something to do with the direction of normals? ..or
back culling? Most of the geometry is spherical and is
generated by
marchingcubes->decimate->polydatanormals->traingle
strips.
Any pointers to the functions that need to be explored
will be helpful. I have tried twosidedlighting too..

Thanks,
Seema
