Curve on an Image into Rhino through Image Sampler??
7 Replies

Hi, I'm working on a project and wondering if it's possible to have a curve on an image, drawn in photoshop for example, turned into an actual curve in Rhino, through grasshopper.  It may make sense…Continue

Unroll Command

Add Multiple windows to a Zone

When using addHBGlz is it possible to add multiple windows to a HBZone at once?  Or would I need an addHBGlz component for each window?  I've tried playing around with the data trees, but it errors saying that the list lengths aren't the same.  One window per zone per component?? See More

Roberto Carrasco replied to Matt Stewart's discussion Calculate if Mesh Faces are touching
"Here there is a solution for this problem. The idea is to explode the faces and get the centers, then you can compare with the "(in)equality" command the position of the center of each face, and if they match you cull them. Once it is done…"

"That makes sense.  Just to get rid of any artifacts or colours in between pure black and white?"

"I think I would increase the resolution of the sampling points and then try and identify the lines from a Voronoi Cell that were representative of the intended curve and then simplify them. See Image"

"That's brilliant.  Thanks!   At this stage an averaged one is what I'm looking for.  But for curiosity sake, how would you go an try to represent each strand.  Don't go ahead and do it, but in theory??"
