Hi R, Understood. I know you've got a heck of a lot on your plate already, especially with the recent changes to incubator. Have they throttled operations to GPU?
Was just checking that I wasn't working on something that was already in pipeline or available. Being a lazy git I was naively hoping someone would post a link to an existing AS implementation. I nearly sprained my brain building a NormalMapper once (http:// videometry.blogspot.com/2009/09/normal-mapping.html) only to see it eclipsed by David Leneart's shaders (http://www.derschmale.com/ 2009/09/19/all-new-normal-mapp-shaders-in-away3d-with-pixel-bender/) a week later.
