Houdini Pendulum Drawing

I remember I was amazed with pendulum drawing when I saw it for the first time. This concept is very simple but at a same time the result is pretty complex. Here is the video that shows the result of using this concept using Houdini. As you can see in the next video, there are two pendulum that are driving a source, emitter. Each pendulum is a sphere that is swinging using RBD Pin Constraint. Then each sphere drive a one end of the IK handle using Rivet. The emitter produce particles which collide and stick to the grid, which is acting as a ground.

A while ago, I was inspired by the video of a showcase of kinetic sculpture made by Bob Potts. I decided to make a animation based on that sculpture in houdini. Next video demonstrates the final result of this project. Here are some references images:   And Here are still images from my final render:     Houdini certainly is one of the most powerful tools for CGI, and most definitely is amazing for making procedural modeling. But in terms of making an organic type object I had a bit hard time. As you can see in the graph image, I had to use quite a lot of node and modification to get a pretty simple shapes.     On the other hand It was very easy to create a procedural shape such as gear. For creating gear I used a next mathematical formula, source form mathworld. when r = a + ( […]
