I forgot to ask the following:<br>
I know that in OpenGL, when you render a large amount of objects, you<br>
can use something that is called "Backface Culling". Then, all faces<br>
that are facing away from the camera because they are always covered by<br>
faces that are facing towards the camera. Is this implemented in VTK by<br>
default or do I have to enable it somehow?<br><br></blockquote></div></div></blockquote><div><br></div><div>Here is an example of how to turn on backface culling.
