I've got another couple of lighting models to cover, and then a summary of a generalised "base" for them. Hopefully have that sorted over the weekend. Time permitting of course..
btw, in an attempt to make this post mildly informative... I think you should definitely read does OSS make bad software feasible? from the lounge. Sadly I've nothing to add to the topic and I think I've ++rated the key players or I would show my appreciation for it [smile]
I read it along with many of the attached references today, and I honestly think it's one of the more intelligent threads on the topic I've read in a long time. I like the whole OSS/Linux thing on paper, but the whole attitude/ego/politics/'religeon' thing amongst it's followers really annoys me.
