SOPs

So since I'm led to believe that you have no idea what Houdini is or how it works, I'll give you a little back ground. Houdini is the 3D FX program. It can do just about anything. The big part about learning how Houdini works is learning how to use a node based workflow and procedural workflows. Basically a node is a self-contained program that preforms a specific task: e.g. extruding a polygon plane. This node has inputs and outputs that allow you to connect it to other nodes. So you could make a node that creates a box, that box then gets outputted to an extrude node that extrudes one or more faces, the extrude node outputs to a smooth node, etc. This allows you to change any one of those nodes and you will see results down the line.

Anyway SOPs stands for Surface Operators. It's the network in Houdini for modifying geometry. Anyway very cool stuff, my first project I'm going to be doing is modeling a hand in Houdini. I'll post more when there's something else to say.
