[vtk-developers] VTK and transparency problems

[Prabhu Ramachandran]

Hi,

Every so often we encounter users (on vtkusers and elsewhere) who run
into difficulties with VTK and transparent actors.  VTK does so many
things out-of-the-box and does them so well that they are usually
quite surprised that something that *they* think ought to be a simple
issue does not work correctly at all.  

I am no expert but do understand that this is not a trivial thing to
solve especially when performance is concerned.  However, this issue
comes up very often and the requirement is not entirely unreasonable
either.

I noticed that Clinton Stimpson had this response:

It appears from his comments that this approach works 90% (?) of the
time.  So would it be possible to make this the default behavior as
part of VTK?  Or is there a better way than this?  Comments?

Thanks!

cheers,
Prabhu
