Re: Algorithm help / Connecting Centroids
I would point out the interior of the bubbles form a 3D Voronoi diagram. Yes, that's it. I already knew, but thanks for bringing it up, it is a interesting reference. It has lead me to check the Voronoi diagram algorithm. The method most used is 'Edge Flip Algorithm for Delaunay Triangulation', and...

Re: Algorithm help / Connecting Centroids
Looks like a fascinating project! Thanks! We brushed on this earlier, but how does the transition from 2-D to 3-D affect those intersections (the red and black dots from the original post)? I can't immediately picture if there would still be only two classifications of intersections. Indeed when yo...

Re: Algorithm help / Connecting Centroids
Hello, I have been on the creative-side of developing this Dynamic Foam project with 'AstroCoder', and here is some extra information for why those centroids need to be connected and form a network. I. Dynamic Medium II. Fields and Boids III. From Boids to a PBD Network IV. Curling Motion V. PBD VI....

Re: Elastic Slippery 0vals
It looks like you are trying to get some kind of cohesion? Yes, but in a natural way. Check out this sketch, and imagine a Newton's Cradle with two 0val particles instead of spherical balls. Now instead of having them fly against each-other and hit each-other hard (BAM!) as depicted in the left col...

Re: Elastic Slippery 0vals
If you just want to due pure collisions then your job is much easier. Set the restitution for all bodies to 1, and be on your way. You could even add some code the the Sequential Impulse Solver to ensure that for each collision the kinetic energy is conserved. Almost none of the Boid-rules are need...

Re: Elastic Slippery 0vals
What exactly is the question, what do you need help with? Have you tried to implement your idea at all, i.e, you have created the mesh and used it in bullet but haven't gotten satisfactory results, or are you at square one. You could say that I'm at square one. I have done some collisions in Blende...

Elastic Slippery 0vals
Hello, Perhaps this post should be in the 'Career Opportunities' section but I'm only looking to find a solution to one particular problem, anyway ... I'm a Bullet-user in Blender, and I would like to simulate a collision between two 0val particles that are 100% elastic (Coefficient of Restitution =...
