Atom Posted December 9, 2015 Share Posted December 9, 2015 (edited) Hi All, I am trying to make a rounded plexus style effect. I have the basic nodes in place but I can not figure out a couple of things. 1.) How do I delete the points that are not connected? 2.) How do I make my straight lines into arc line curved lines as shown here in this image? I have a convert polygon to bezier but that seems to have no effect? NOTE: I did review Mike's setup on this topic and while it does work in the viewport, it will not render without crashing or hanging up Mantra H15.0.313 (on my machine). I get about 13 frames and then it is dead. I need to render several hundred frames of this animation style. ap_plexus_attempt_1a.hipnc Edited December 9, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
mestela Posted December 9, 2015 Share Posted December 9, 2015 haven't looked at the rendering problem, but the curved lines and orphan points i could do. -a clean sop has the option to remove unused points -because you've converted to bezier curves with 0.5 divisions, you already have a point at the midpoint of each line, you just need a way to get to it. a uvtexture sop in 'rows and columns' mode will give you a ucoordinate you can use, then in a wrangle you just move the points that have uv[0] == 0.5. needed a mild rearrange to make sure the orphan points were removed before the convert, and before the copy sop, otherise you'd get spheres copied onto the midpoints of each line, which i assume you don't want. ap_plexus_attempt_1b.hipnc Quote Link to comment Share on other sites More sharing options...
Atom Posted December 9, 2015 Author Share Posted December 9, 2015 Thanks Matt, that did the trick. I didn't realize you could feed a rand() function a vector seed and get a vector returned. One other thing I have been trying to do is to modulate the entire structure over time. I thought I could simply put a Mountain right after the sphere and animate the offset. But this causes a frenetic pulsing in the lines (both yours and my version). Anytime I try to deform the source geo before the lines they pulse that way. If I put the Mountain at the end I only modulate the lines and the spheres disconnect. Any ideas for modulation? Quote Link to comment Share on other sites More sharing options...
mestela Posted December 9, 2015 Share Posted December 9, 2015 put a point vop that adds turbulent noise (or something) immediately after the connect adjacent pieces sop, that should work. Quote Link to comment Share on other sites More sharing options...
Atom Posted December 11, 2015 Author Share Posted December 11, 2015 (edited) Thanks again Matt, the point vop for modulation does work. I extended the range of your new scale parameter to go negative which allows for a spider web look. ap_plexus_attempt_1c-2.hipnc Edited December 11, 2015 by Atom Quote Link to comment Share on other sites More sharing options...
