I’m trying to model the movement of an upfolding textile shading device, which should work like this (the bottom and top points should move in a vertical line):
- Closed state
I created a Grasshopper definition that I would like to animate with an “opening fraction” slider in the end. However, I’m not nearly done yet… I fail to solve creating the frame sweeps in the proper direction, until an opening fraction of 0.292 it works as expected:
When the opening fraction is equal to 0.293 it flips direction:
In general I have issues using Sweep1 with Grasshopper, I don’t reall understand why this is happening. If you examine the wireframe only, it moves as expected, I suspect I have problems with my Orient geometry and Sweep1 components at the end of my definition.
Any ideas how to do a proper sweep that wont flicker all around the rails? Or should I use some other command?
