aspect Posted March 30, 2010 Share Posted March 30, 2010 hi all, would like to know how to make water bubble geometry in geo. i want to have spheres interecting sharing a flat surface and not the curve surfaces when i surfsect (for nurbs) or cookie (in polygon)... i tried to scale down to 0 after surfsecting two sphere taking their intersection. this may work for 2-3 spheres... would like to know if there is more efficient way to do it especially when i want to try it on large numbers of interecting spheres. thats something i like to acheive thanks Quote Link to comment Share on other sites More sharing options...
quarel Posted April 1, 2010 Share Posted April 1, 2010 i want to have spheres interecting sharing a flat surface and not the curve surfaces It is mathematically impossible. In huge or small scale neither. (I think) I tried it trough circles and always the intersection must be curved. Quote Link to comment Share on other sites More sharing options...
pclaes Posted April 1, 2010 Share Posted April 1, 2010 (edited) As I mentioned on the sidefx forum, voronoi and a bit of cookie for the outer geo. It's a bit rough and the geo needs some filtering (you got primitives lying on top of each other for the inside geometry). You can literally slice one piece out of the entire bunch. The creasing is so the subdivision surface doesn't touch the inside. You'll need Johner's voronoi otl.

borbs727 Posted November 19, 2015 Share Posted November 19, 2015 I inserted houdini's standard voronoi fracter sop instead of the otl you mentioned (because I couldn't find it). It seems to work, is there any difference? Quote Link to comment Share on other sites More sharing options...
jkunz07 Posted November 20, 2015 Share Posted November 20, 2015 I think that is the same voronoi fracture SOP, but an older version before SideFX transitioned it into their own otl. 1 Quote Link to comment Share on other sites More sharing options...
