Construction Challange (BEVELING related) - ggaliens - 09-12-2013 Construction Challange (BEVELING related) Let's start with a Dodecahedron. Why not. Suppose you had a simple beveled Dodecahedron (smaller than src object by the bevelling). Take the large faces left after BEVEL ... and extrude them outwards. Call this BEVEL-AND-EXTRUDED (bae). Now ... subtract bae object from original dodecahedron ... you should be left with the part that was originally bevelled away. So you would be left with a ROD-BASED dodecahedron ... a wirecage with some thickness so as to be a manifold. The general cross section of a strut in the final result woudl be triangular. Let's call the operation BEVEL-INVERSE (on solid). It is an operation of bodies in my head as opposed to edges or faces. Just the way I prefer to think of it. I found this hard to do last night having tried it for a good while ... hard to do without BOOLEANS. Probably because I'm not being imaginative at this task. Anyone ... wa way to get the 3D INVERSE of a bevelled Dodecahedron ? Maybe call it the "bevelled complement" ? I have something very cool to show next after I figure out BEVELED-COMPLEMENT. RE: Construction Challange (BEVELING related) - ggaliens - 09-13-2013 http://www.youtube.com/watch?v=DP-46jDLXSc&feature=youtu.be There has got to be a better way to create weld-able tidbits of foam. Seems like to many steps. RE: Construction Challange (BEVELING related) - micheus - 09-13-2013 I followed your steps and get the last one. Now ... ??? RE: Construction Challange (BEVELING related) - ggaliens - 09-13-2013 Bounding hulls ... enclosing hulls are supposed to be same for before and after. I probably didn't express that very well in writing. The idea there is that when you have a packed dense array of these (foam) ... you can "WELD" the skeletal foam items together and the shared edges "blend" together via coincident faces. I'm uploading a new result now. Look in the manifoldlab folder ... "3dfract" and you will find a file "monodisperse" or something like that. This is the "input file" that I'm eventually trying to apply this workflow to. It is too heavy so I have to delete some tidbits. Still seems a bit of a hassle to get to the weldables. I Weld using manifoldlabs STITCH function. I have to play a bit with stored seletions ... not that the are bad. I just wanted something more clever and fewer steps. More results ... after still too many steps http://www.youtube.com/watch?v=qFEm7m9nW5c&feature=youtu.be RE: Construction Challange (BEVELING related) - ggaliens - 09-20-2013 I've been working trying to EMPLOY Centroidal Voronoi Tessellation iterative techniques to very simple shapes to try and get more idealized foam ... regulated foam. It is pretty tricky at the shape boundaries to I stick to a sphere. Even there it is a bit hard to smooth the foam. I wish Jotero and Nspokes were around to help.
