Marching Cubes Grasshopper Plugin ((FULL)) Download
Hermogenes Smardon
Some of the work posted lately by Nick Tyrer has gotten me thinking about marching cubes again...I had done some stuff with marching tetrahedra and cubes a ways back, and with some new inspiration (and a little time I could carve out today) I figured I'd take a stab at trying to make it more flexible and robust. There was a lot of room for improvement...certainly there still is. This is really a work in progress, so all caveats apply to the script...it can probably break, hasn't been thoroughly tested, etc. But I probably won't be able to do too much more with it for a bit, so I figured I'd put it out there if anyone wants to play with it.
I am relatively new to rhino and grasshopper but have knowledge about 3d objects from some years in blender. I need to create an organic shape that looks something like the pictures at the bottom (Especially the first one and also that last one).It is very important to me that it is tileable and 3d. I found some tutorials, but it's never something that really looks how I want it to. I thought about creating it somehow with a physics plugin like kangoroo but I don't know how. Also the repeating, tileable method would be hard there. I also thought about not even using grasshopper but creating that stylie with a subsurf. But It might not be the same.
Here is a pythonic version of the marching triangles (inferred from millipede gh plugin) if you want to do something about it (see also attached gh file). I think it should be more robust and a lot faster than the legacy version that relies on mesh/plane intersections (though it requiers to triangulate the mesh first).
I wrote a quick Grasshopper sketch to play around with these surfaces (sometimes called medial surfaces, but as far as I can tell, they have not yet been used much as a generative design technique). Its very crude at the moment and limited to only 2 curves, but you can see that it generates some interesting forms. (The chunky Lego aesthetic is only temporary, until I get around to having a go at implementing a marching cubes algorithm)
