Hello, I want to change the color of particles according to their distance to each other via "pop wrangle". This is my approach but its not working as expected. Unfortunately i have no errors or something like that so I cant get any further. If somebody has a hint for me it would be much appreciated. kind regards Jon vector pos; vector col; float maxdist = ch("distance"); v@Cd = set(0,0,0); int handle = pcopen(0,"P",@P,ch("searchDist"),chi("maxPoints")); while ( pciterate(handle) ){ pcimport(handle,"P",pos); pcimport(handle,"Cd",col); if( distance(@P,pos)< maxdist) { col = set(1,0,0); } } colorParticlesAccordingToDistance.hipnc
