Short week here in the States so I’ll leave you with some light reading. The reason I say light reading is because Matt Estela has a way of explaining complex topics in a very simple and effective manner.
Points, Points, Points
Head on over to Matt Estela’s CGWiki and read this in depth article he wrote on Houdini’s use of points, vertices, and primitives and why points in Houdini are a big deal. I’m sure you will learn a thing or twenty. While you are at it, support his Patreon so he can continue creating great Houdini learning material.
