Daniel Piker replied to Fabio's discussion Wind - Mesh against solid object in the group Kangaroo

"Hi Fabio. CollideSurface and CollideMesh only check for collisions between points and the surface/mesh. As you show, this can mean that a mesh between the moving points can sometimes penetrate the volume slightly. Things can be improved by using a…"

Wind - Mesh against solid object

Hi Everyone.Sorry if this sound a bit dull as a question.I'm working with wind force to simulate the behaviour of a mesh wrapped around a sphere.How can I set the closed Brep to be perceived as solid abject and avoid the flying mesh to fly through it? I've tried Collide surface but it hasn't worked. Please help if you can.See More

Kangaroo/ Wind Force/ Objects

Hi Everyone. I hope someone can help me with this.I'm using Kangaroo and wind force on a series of meshes. Those meshes are integrated within a structure. How can I set Kangaroo to recognise the structure as a solid object and to not let the meshes flying through it?Thanks in advanceSee More

"Sounds good: as long as there is a plane for Delauney, this method should work. - Giulio_______________giulio@mcneel.com"

Fabio replied to Fabio's discussion Surface From Non Planar Curve

"Hi Giulio. Thanks for your reply. I managed to get the same results applying the divide curve and Delaunay mesh command. I don't know if that is the right path to go but it works for now."

Giulio Piacentino replied to Fabio's discussion Surface From Non Planar Curve

"Hi Fabio, I'm not aware of a method for that, but if the curve is a polyline, you could use the Rhino _MeshPolyline command to directly obtain a mesh. I hope this helps,- Giulio_______________giulio@mcneel.com"

Fabio replied to Fabio's discussion Kangaroo - Wind Vector

"Hi Daniel. I wonder if you could help me. I have generated my meshes but even if I flatten the curve/meshes before joining then, the results are quite odd. The wind is applied to one side of it and even if I try to change its coordinates, the…"

Andrew Heumann replied to Fabio's discussion Kangaroo/Mesh/Anchor Points

"Ah, I see - in that case the curve-proximity method I mentioned will do the trick. You can get the curves at those ridges by extracting isocurves from the original loft, and then find the distance from each mesh vertex to those curves, and use that…"

Chris Hanley replied to Fabio's discussion Kangaroo/Mesh/Anchor Points

"very nice andrew! Does that approach work for points that don't lie in the same plane? I thought he was trying to get the points along the top edge of the sides...where the side walls would meet the roof.....(sorry, that's not…"

Andrew Heumann replied to Fabio's discussion Kangaroo/Mesh/Anchor Points

"I think you can do this dynamically. You've already got the complete list of vertices from the mesh decompose component - now just cull or dispatch them according to some test which governs whether or not they should be anchored. (For instance:…"
