Hi,
I simply want to find the vertex number of a point inside a given primitive in VEX
For example :
I want to find the vertex number of point 45 in primitive 41 (which is 0)
I want to find the vertex number of point 45 in primitive 31 (which is 2)
I want to find the vertex number of point 55 in primitive 41 (which is 3)
I tried int pointvertex(<geometry>geometry, int point_num) function,
int primvertex(<geometry>geometry, int primnum, int vertex)
I also tried primvertices or pointvertices
But they never gives me the good number, maybe because this is linear vertex
Any help would be appreciated
Thanks !
VEX get the vertex number

You need vertexprimindex [www.sidefx.com] to convert from linear (“global”) vertex ID to “local” (within the given primitive).

Ahh okay, i've missed this one !
so I did something, a little bit tricky, I don't know if there's a simpler way but I found what I want.
Thanks !

int point = 55; int primitive = 41; int vtxList[] = pointvertices(0, point); i[]@vtxList = vtxList; int primList[]; foreach(int vtx; vtxList) { int prim = vertexprim(0, vtx); append(primList, prim); if(prim == primitive) { int vtxNum = vertexprimindex(0, vtx); setpointattrib(0, "vtxNum", point, vtxNum, "set"); } } i[]@primList = primList;
Thanks !
