Hi Aaron,

I can't seem to figure out how to use the de9im class in boost geometry (posted SO question here http://stackoverflow.com/questions/23684869/is-the-boost-de-9-im-struct-usable). Maybe I'm just missing something but is it even in a usable state yet, an example of a point within a polygon calculation would be greatly appreciated.

It doesn't make sense to discuss on StackOverflow in the comments so I'd like to move the discussion here.

You said:
"Already using the rtree, I only ask this question because the JTS implementation of within using a prepared geometry is killing boost::geometry::within, and JTS is in java"

I'm curious how did you compare the libraries?
What was the test case?
Many tests for Points within only one Polygon?
If yes, then have you tried to first calculate the bounding box of a Polygon and use it for the first check to eliminate this difference between libraries?
Are the benchmarks available somewhere?

Adam
