As some of you may know, StudyBuddies.com (you can check out what this is on my portfolio page) is currently being developed as a mobile application! In terms of general progress, I’m happy to announce that I have created an official walk through of our UI design! Please check out the images below and see what you think as of right now.

Disclaimer: This is not going to be exactly the design of the application, however it gives us a good idea of what we’re going to be striving towards in terms of UI.

Anyone who’s done anything with shader programming knows that shadows are probably one of the most annoying things to render. The current ideal method for this is what’s known as shadow mapping. But even that comes with a plethora of problems including aliasing, which biasing does not necessarily fix. Once we fix that problem with variance maps we still get problems with light bleeding! Pretty much the ideal way to create these non biased and anti-aliased shadows is to use these variance maps but combined with summed area tables for juxtaposing texture data. Overall its about a 20 step process although effective. Hopefully we’ll someday be able to create a more efficient process for environment shadows.
