New here to the forums, and relatively new to Grasshopper. I am trying to simulate a drawing machine, similar to a harmonograph or pantograph. I’ve read these ones here:
and
The difference is I would like to create the simulation using physics simulation with Kangaroo. I think I’ve go the right idea going, but could use some help fine-tuning it, as it’s not behaving exactly how I want, especially with the timer running. I’d like to make a flexible script so that I can increase the complexity (number of line segments), and it still works physically
Here’s a way of doing it that should make it easier to modify the parameters while it is running.
Anchors have 2 inputs - P is the initial location of the points you want to anchor, and T is the position you want to fix them in. Ideally here we only want to move T while the solver is running.
Fantastic, thanks for your thoughts. This shows that i was indeed sort of on the right track, just needed to sort out a few things with the anchors. Thanks for showing me the way!
This is really helpful, thanks for your input. This is a really elegantly simple solution.
Next step I think would be to try to rotate the drawing plane as the points are being recorded… I will give this a go and update again with the progress.
Hi all-
