Can I make a moving clipping plane?

[farshizzo]

Here is an example that applies a clip plane to a model and updates it every frame so that the plane is relative to the current viewpoint. Let me know if this isn't what you were asking for.

import viz
viz.go()

viz.add('ball.wrl',pos=(0,1.5,2))
model = viz.add('gallery.ive')

import vizact

def UpdateClipPlane():

	mat = viz.MainView.getMatrix()
	mat.preEuler(0,0,90)

	p = viz.Plane()
	p.setQuat(mat.getQuat())
	p.setPos(mat.getPosition())
	model.clipPlane(p)

vizact.onupdate(viz.PRIORITY_LAST_UPDATE,UpdateClipPlane)

You are the man. This is absolutely perfect. Just what I was trying to do, except my attempt looks like a Rube Goldberg machine next to this solution. Thanks!

One last thing: Is there an easy way to offset the plane a little bit to the right?

Hmm, thought I could edit posts here. Anyway, I tried to offset the plane by preTrans-ing it right after the preEuler, but it doesn't seem to be working.

Edit: Nevermind, got it. PreTrans-ing before Pre-Eulering did the trick.
