hello,
I have made physical model of one prototype with 2 canes with concept of bending active system. Now I am trying to convert it into digital medium. I have gone through the videos of related to this. But I am not able to get the desired solution with kangaroo solver.
help me to figure it out.
Thank you for your valuable time and consideration.
I’m not an expert in Kangaroo, far from it, but I see something in your model that I also need help with and think is a problem — the tie points. These are what I would call reciprocal constraints on the bending. That is, the tie points influence how and in what direction bending can occur, but the bending also changes the constraint’s location in absolute space. I think this introduces a degree of recursion that, if it is possible, is very very tricky.
My project, for example, is also based on a physical maquette. It uses multiple creases and cuts in a sheet material. As the creases are amplified, they bend the material and are therefore also moved by the material in absolute space. Also, after the creases are made, you can move them around in a way that is constrained by the material and this has a significant impact on the bending caused. The whole system is an interdependent loop. Even faking some of these constraints, I so far have failed to achieve a complete simulation.
These old project videos might inspire some ideas, or at least demonstrate how to model the input polylines:
I can link to some papers we wrote when I’m on my laptop again. Some fond bendy memories
