generative modeling for Rhino
I'm the first time here and ask me, is Kangaroo the right tool for placing tablecloth over a table or a sheet over a bad? I need this for photoreal still rendering. I tried several example files, but nothing works. Would it be difficult to work with Kangaroo on scenes like this?
It depends on the level of realism you want, but yes, draping over objects is possible.
For the cloth you need springs to resist stretching and shear, then hinges between each triangle to resist bending. (the video above shows the result of varying the bending strength)
Also, bear in mind the collision detection in Kangaroo is fairly basic - it works on points/solids only, so some edges may penetrate the volume, and it can be quite slow compared to other functions. There is also no self-collision, so cloth cannot pile up on itself.
Here's an example definition
Did you already install the Kangaroo plugin ?
