Convex decomposition keeps the original shape of your object and cuts it up into chunks for better understand it. The goal of creating a proxy, is to keep the object simple, but also keep it's size, shape, and structure. However, it cannot work with deforming geometry. Let's break down a few of them.Ĭonvex decomposition can help create better collision with static objects. There are a few basic ways to create proxy geometry. You can then feed into the DOP network as a static,deforming,RBD, or other object. The process of creating and adding your proxy happens before you add your collision object to your DOP network. This helps reduce any existing problems from your existing geometry that you are trying to simulate. In a simulation you may need to create proxy geometry for your collisions.

In this article I will be covering how to figure out where and how to fix your collision objects. Collisions can also be one of the easiest or hardest things to fix. One the biggest problems that happen in creating simulations is dealing with collision objects. Houdini is such a complex software, that sometimes everything or one thing may be wrong. One of the hardest things to do to in Houdini is how to problem solve when things go wrong.
