Slimesunday Posted October 26, 2016 Share Posted October 26, 2016 Still learning here but hang with me. I have a torus which I have thrown into a solver then into a point vop. Im using Cd to control the amount of displacement over time. It creates a cool growing effect but I don’t want this to grow infinitely larger; I want to control the growth by having it fill the volume of another torus. I tried setting the secondary torus to Cd = 0 and then transfering that attribute to the displacement channel but my attempts are failing. Does anybody have any idea how to use the secondary torus as a boundary? or even better have it eventually fill the torus? .hip file is attached vornoi_growth.hiplc Quote Link to comment Share on other sites More sharing options...
dchow1992 Posted October 26, 2016 Share Posted October 26, 2016 (edited) you can test it against an sdf of the boundary each frame if you've never used an sdf before, it's a volume representation of a shape with negative values on the inside and positive outside within the narrow band. there's built-in vex functions to sample volumes and in the file I use the border of the sdf to control the displacement vornoi_growth.hiplc Edited October 26, 2016 by dchow1992 7 Quote Link to comment Share on other sites More sharing options...
