Just thought I would post a status update on this. It's been a busy week, but I've managed to get the base of the framework done and I'm wrapping up two shaders to go with the initial release. One on basic lighting and the other on generating old photographic images. The framework is a bit larger than I was hoping for, but I forgot how much code is involved just to get some simple GL apps up and running. I will need to provide documentation in the framework release package to help explain all that, so that's more added on my plate.
I have attached some screenshots showing the current layout (still a WIP). I'm trying to keep it compact, with the width of the app set to 800 pixels (apparently that's the size of the article section here) and using a tab navigation system (UI is powered by jQuery). You can play with some shader settings, view the source, read the theory, and download the framework + shaders. At some point I'm hoping to see a table of contents with a listing of all the shaders and someone can just click and jump right into it. After they get what they need, the can browse for more.
Dia, the only thing I'm curious about is your policy on using iframes. I didn't want to manage a colossal HTML file with all that stuff in it, but I know iframe's are not considered best web practices, especially for search engines. Let me know your thoughts on that and/or how you want the final package to work out.
