algorithmic modeling for Rhino
Pivoting ball, ~1600 points, ~11 sec
ok thanks Vicente!
I don't know anything about Millipede..Why do you set N-1?
I asked you how to have metaball mesh from curve because I'm trying to optimize metaball's surface (exposition) or other features (volume). I want to control metaball's genesis through moving point. Using isosurface componente I don't know how to control them. Can you help me? many thanks
- The idea with using the isosurface component is that you don't need those polylines, you can do the 3d metaballs directly.
thanks Vicente! but i have two questions:
- What expression Have I to set in N?
- do you know how can I have a mesh from my lines (see the image)
RWNB, I searched the forum since I'm sure it has been done before and found this thread with Mateusz suggesting the exact same thing. Maybe you can post the questions there:
can you post your work independently of mateusz discussion.maybe there are some questions regarding to your work and millipede.at least i had a question. ;)thanks
andreaquartara, you can already do 3d metaballs using the isosurface component of the millipede plugin.
It uses marching cubes which is more suited for distance fields. Ball pivoting is more suited for direct point cloud reconstruction. The 2d metaball component already uses marching squares so this is more direct:
fantastic work..I'm trying to obtain a mesh from metaball's curve too..I'm grateful to see your GH script..
great mesh work!
Daniel : I will try to publish this script after easter time. It's slow (I cannot find any simple way to make it faster), so I can imagine your idea only with a small amount of points. In the paper, they say that 11k points takes ~sec to compute... so my implementation is really primitive.
Vicente : Yes, the inital points are made like that. It's the fastest way to obtain non-obvious point cloud suitable for the pivoting-ball. After generating the points I clean them up with RemDup points component (kangaroo).
Awesome work Mateusz!
