Vertigo setup

i have a box and want to obtain a perspective where the frontside (side facing the viewer) always remains undistorted by the perspective projection.
can someone help me understand how to set up the scene ?
the vertigo help says “objects at a certain distance keep their size” but how to specify the distance ?

just found this example of what i was trying to accieve https://vvvv.org/sites/default/files/imagecache/large/images/filename.jpg http://a0.vsoh.com/l90q.gif

hello, I unlinked WithinProjection (Transform), set to Solid [Fill (Ex9.RenderState](https://vvvv.org/documentation/Fill-(Ex9.RenderState) and set TranslateX pin (of transform linked to Constant) to 4, and I think it gives you what you need.
You should try with a more complex scene (something with more reference points as in Using Cameras from C4D via Collada I posted a while ago), to better understand what’s going on in your patch.

Hope it helps, as your example helped me.
