One thing I neglected to mention in that post is xyzdist and mindist both require primitives in the geo stream you’re looking up<\/p>\n

So they aren’t totally apples to apples with nearpoints\/pcfind<\/p>\n

okay i couldnt help myself, but here’s single pass random overlapping dots “`c #include #include
