[vtkusers] Hidden Tetrahedrons and Visualization

[Thinnes]

Dear vtkusers,

I have a question about visualization:
Currently, I display on the screen a dataset build with a thousands of
tetrahedrons.
All tetrahedrons are displayed on the screen, and I would like to know
how to display only the visibles tetrahedrons
related with the camera position. I mean,  to not compute the hidden
tetrahedrons.
Is it possible?
If yes, how to do? Which VTK functionalities can manage that.

Thank you for your help.
Alexandre
