This project was based on a chain reaction machine with a ball following the track projected. Done in Houdini with the purpose of conducting a research about RBD Objects and their different types of solvers; and how to set up the scene and node chain for the simulation to work smoothly.
The projected path is the ball falling down the platform and rolling down the helix to fall onto the ground.
First thing to do was import the assets into the scene, make them static and RBD Objects respectively and go on the AutoDopNetwork to adjust the solver type to Bullet with Concave Collision. Because of the complex shape of the helix, I had to go into the sphere's physical attributes and adjust them to make it stay on track without using any constraints.
Voila! Running the simulation in real time finally gave me the results I wanted and that seemed like a natural reaction in real life.
