Right now I'm working on my skewbe mapping paper, so I'll copy my most recent (read: only) LiveJournal entry about it. This will pretty much only be relevant to #graphicsdev'ers, who know a thing or two about skewbe mapping, and for the rest it'll be a teaser of things to come.
Right now I guess I'll talk about my paper's status. My to do list is copied below:
show image demonstrating necessity of offcenter perspective
properly label matrices (e.g. +X, -X...)
get the two formulas used in the lighting demo
show image demonstrating where an artist could do some face culling
have set of images demonstrating results under different scenarios
write conclusion
write acknowledgements
For the first image, I still need to plan exactly what the image will be, and the associated text. Right now, it'll probably be like this image:
...that I showed #graphcisdev early on in its development to show how the cubemap will be generated, except with the off-center projections corrections that moopy and redbeard suggested to change it back to a skewbe map (in case you don't remember, it was basically a frustum map for a couple days).
For the second, I'm not sure what labels I should give the matrices. Maybe, say, X_+ or X^+?
The two formulas are going to be a bit bit tricky, because I think my computer at home got shut off, meaning I can't connect to it, meaning I can't look up the code from here in Edmonton. Although, Pfhor has the first formula I need, and I think I remember the second pretty well...
The second image I've got in my head, I just need to author it and make it look all professional-like.
The set of images I can't do until I get my high-end comp going again.
Conclusion I haven't even thought of.
Acknowledgements I haven't thought of either, but it shouldn't be too hard, right?
