Cylinder Transformation/Scale


I wanna do a video mapping on a modeled figure like this.

My Question is, how can I exactly align the vertices and center of 3 sides cylinder/pyramid?

Sorry for that simple question, I am a beginner in vvvv.


This is an obvious question we all ask, I am a beginner too.

This shall be a place for you to start
how to project on 3d geometry and this one draw-lines

You will find some simple setup patches in the above link, play around and read the article again, it would make sense more than you read for the first time.

Have a great day!
