I am currently trying to deflate and fold an inflated geometry. Similar to the following nice video - ok maybe not that many folds, but the same principle. (and my current simulation is also lacking this great soundtrack in the background)
relevant scene starts at around 0:50
Currently I am approaching this challenge the following way:
- set up a Kangaroo simulation with negative pressure applied to the geometry (in order to simulate vacuum)
- making sure that there are no self-intersections by using the
Radii
component - set up “folding devices”, which are controlled by an incrementally growing number (which is retrieved by attaching the
Trigger
component to a number and adding it up every time the trigger runs:
My current solution seem to be a bit of a (non-elegant) workaround. Are there any better approaches to tackle this kind of simulation?
p.s.: as a side issue, I do also have the feeling that the Trigger
refresh system is interfering with Kangaroo’s own internal Trigger
and making everything slower - but I am not clear on that yet…
p.p.s.: I guess the simulation shown in the video are actually several separate simulations stitched into one animation?
p.p.p.s.: a cool video, I just found regarding this topic:
