I have a set of random points in 3D space and each one of them has a variable which describes its importance.
I use the FastUniformGrid and Transform filter to generate a bounding grid for the points as below:
NOTE the grid in the Y direction is just one cell
I would like to have on the grid cells the number of points they contain. Furthermore I would like to know the weighted number of points based on the importance variable.
Is there a quick way to do this with combination of filters?
