This is the tutorial form node flow about how to model the Penrose triangle optical illusion in Houdini. Also render the necessary elements for its composition.
Animating The Penrose Triangle In Houdini
The Penrose Triangle is an impossible figure but it depicts an object which could not possibly exist. It is impossible for the Impossible Triangle to exist because in order for it to exist rules of Euclidean geometry would have to be violated.
