Can I make a moving clipping plane?

[Salvar]

I'm setting up an experiment in Vizard, and I need to control how much of an object a participant can see during movement. The trick is that I don't want to block anything else but this particular 3dnode, so applying a global fog or clipping plane is out of the picture.

So I had the idea of applying a clipping plane to the node, and using a vizact ontimer event to update its coordinates according to where the viewpoint is a t the time. This is proving difficult.

I basically want a clipping plane that's the equivalent of a horse blinder on the right eye. One that blocks everything on your right side from view, and stays in that position as you move and rotate in the world. Is this possible?
