  1. Bezier Plexus

    Hey everyone, I'm slowly starting to learn Houdini and I've had a bunch of help from the forums so I wanted to give back and share a hip that I just finished. It's not the most complicated thing in the world, but I learned a lot while making it, so maybe it'll help someone else out. Feel free to offer any suggestions/improvements on it (especially when it comes to how I coded the vex in the attr wrangles). Mike mb_bezier_plexus.hiplc
  2. Hey everyone, I currently have a plexus effect by blending a few tutorials together (tinytuts and Danil Krivochko). I'd like to take it a step further and create a persistent plexus effect where the connections at frame 1 remain throughout the simulation- never breaking or creating new connections. I have this code from the tinytus tutorial: if (ptnum % ratio == 0) { int myprim = addprim(0,"polyline"); int nearpts[] = nearpoints(0,P,maxdist,maxpts); for (int i = 0; i < len(nearpts); i++) { addvertex(0,myprim, ptnum); addvertex(0,myprim, nearpts[i]); } } It's creating primitives based on nearby points. So in order to get the persistent plexus look, I need to use maxdist and maxpts to create the look I want, but be able to keep max distance from influencing the connections after I get my initial look. I think I need to start by establishing a connection between points at frame 1, so they remember who they were connected to during the simulation. I might be able to do this by somehow storing nearpts[] data into each point with an attr? Or maybe I can create a new if statement that says in pseudocode that may or may not look like python: int nearpts[] = nearpoints(0,P,maxdist,maxpts); if frame == 1: create a list called initpts and store any points from nearpts[] into this new list else: pass Then change the for statement to say for each initpt in initpts: addvertex(0,myprim, ptnum); addvertex(0,myprim, initpt); Is there a way that I can utilize python to create this effect here? Another thought I had was to use a solver sop because I've seen that it can calculate what went on the frame before, but I'm really struggling with how to proceed with this direction. A nudge in the right direction would help me out a lot, thanks! Here's my file so far. od_persistantPlexus.hiplc
  3. Hey everyone! After about year and a half after I switched to Houdini from Autodesk Softimage I decided to create series of tutorials with a things I`ve learned so far. 3 is ready for now, the target is to make 10 =) Plexus-like effect Prometheus-inspired "scan" effect - Sound driven deforms on animated garment All sources are available for download in video description on Vimeo. I`ll update this post as new tutorials will be available. UPDATE: Number 04 - VEX trails on vortex-like points movement
  4. Hello. I finish my latest development tool for motion designers and projection artists! It is fast and simple solution. Hope you will like it http://www.orbolt.com/asset/e3d::pointBuncher::109 https://vimeo.com/106270443
