Hello there I'm a new person to Houdini and running into an issue.

I have a Geo and I'm trying to get where all the line merge into a single point to place said points into a group instead of manually selecting each vertex.

I started with- int near = nearpoints(0,v@P,0.01,5);but kinda had a brain melt after that. Vex is also very new to me as well


Any help is greatly appreciated!

You might want to provide and example of what you are trying to do. Also do you actually mean vertex or point. If new then the way houdini deals with all this is slightly different to other 3D apps - This explains quite nicely - https://www.tokeru.com/cgwiki/Points_and_Verts_and_Prims#Shadesails_and_verts_and_prims [www.tokeru.com]

Hi,

Here is one way using pcfind:

int maxpts = chi("maxpts");
int pts [ ] = pcfind ( 0, "P", @P, ch("radius"), maxpts );
if ( len ( pts ) == maxpts )
    i@group_pts = 1;
