Hi,
I know point clouds can be used to blend/average attributes within the radius of each point. Is there a way to do the same where it only does this if:
1. A point is connected to the same surface as the current point.
and
2. A point is within X units distance on the surface from the current point. Not point to point straight line distance, but the shortest surface distance between 2 points on the surface. I am not sure if there is a proper name for this. Not the best pic but something that looks like this:
As you can see the length of the shortest path that lie on the surface. The surface can be polygons or NURBS. This can't be faked with neighbour functions as edges are too coarse.
Can this be done using point clouds? If not, VEX? If not, then any other solutions in Houdini? It's gonna be a per point operation though just like VEX/VOPs.
Thanks
