Matt,
I'm interested in taking particle-only data and putting it into a regular, multi-level grid structure that has yet to be created. I think using a kD-tree, where we specify a maximum number of particles in a given region, could be used to identify regions that should be covered by grids. Do you think that your kD-tree code would be suitable for this?
Sure, you'd have to write some kD-tree grid data access functions. But it shouldn't be too difficult. It also currently has the number of points per bucket hard-wired at 12, so that would have to be changed into an input parameter. _______________________________________________________ sskory@physics.ucsd.edu o__ Stephen Skory http://physics.ucsd.edu/~sskory/ _.>/ _Graduate Student ________________________________(_)_\(_)_______________
