Dan,
One other detail on this is that typically the speed improvements are only seen if you render directly to the screen in real-time. This has some drawbacks with the tiling expectation. That also makes it harder to integrate with our stuff without having a spacial edition that only runs on Windows 7. It would be allow more attractive if I could render to a bitmap at the same fast speed.
We also find that the raw drawing is about 1/3 of the entire process overall or less. Depending on the case most of the time is spent reading the data, figuring out what data to read, converting the data, projecting the data, prepping it to draw, making style choices etc.
Don’t get me wrong we are still looking at this technology just wanted to give you a slightly bigger view.
