In my research project, I set up a basketball hoop and a basketball.
First I modeled the ball and the hoop in maya. I then exported them out as objects. When bringing them into Houdini, I first made a sphere then went into the geometry mode and brought in the ball and replaced the sphere with it.
The hoop was a geometry node.
I made the ball a RBD Object and the Hoop a Static Object. I added a ground plane and stretched it to the scene size.
For all the technical stuff, I matched some of the nodes from the wall fracture project.
Some how i ended up with a second ball, which I think was a happy accident since the first ball hits it and pushes it off of the stage. "This court isn't big enough for the both of us."
