find points within range

[freaq]

given a grid, and some scattered points,
I want to know the "density of the points on the surface.

 

ideally mixing the colour value of these points by distance. ( essentially an attribtransfer that just adds all the values together weighted by the distance.)

but as a simplified version something like this could work:

4 points are closest to point 3 so point 3 gets a colour value of 4.

 

I tried doing this with a point cloud iterate but can't get anything useful going :/

For your simple example you should be able to do it with just a "point cloud open" vop and a "point cloud num found". You set the radius on pcopen and the pcnumfound tells you the number of other points within that radius.

 

You can do the weighted transfer inside of a for loop from there. I'll try to throw an example file together later tonight, if someone else doesn't beat me to it.
