As this is my last year of school, I've been interviewing with various companies and trying to get an on-line portfolio together. I recently had a great time in Portland meeting with Intel.
Last spring I was involved in the research of using non-pinhole impostors for reflections and refractions. We submitted to Eurographics (specifically EGSR), but unfortunately didn't get accepted. So this semester we are looking to work on the short comings that some of the reviewers noted and resubmit to I3D. So until I get that out of the way there probably won't be any new samples/tutorials for a couple of weeks.
As far as for future posts, I've been working on rain as a particle system and as a post process (see Tatarchuck's AMD/ATi paper on Rain). Besides this I've been wanting to have a series of samples/tutorials on different lighting methods. We all know Gouraud and [Blinn-]Phong shading, but I wanted to cover other methods such as Cook-Torrance, Oren-Nayar, Ward lighting and others. I also might do a tutorial on Depth Impostors that would build off of the Billboard Impostor tutorial I wrote earlier in the year.
For now, here's a couple of teaser images that we submitted to EGSR. You're looking through a glass bunny's ear. You can see that with regular depth impostors, you are missing a significant amount of data for the teapot lid.
