[yt-dev] Testing new AMR kD-tree

Hi all, Sam's got a PR out for a new AMR kD-tree: https://bitbucket.org/yt_analysis/yt/pull-request/383/amrkdtree-rewrite-volu... The idea is to make things more flexible, easier to improve, and eventually maybe even move it into Cython. It also includes some really cool improvements to alpha channel blending and the like. (He had a demo in IRC the other day of a plaid background over which he's volume rendered.) This needs user-testing. He has added tests for nose. I think if we can get three more "approve" clicks, which I hope will be from actually having run the code, we can give it an accept. -Matt
