Wow, I can't believe it's almost May already. I also can't believe my last post was back in February! I've had the next installment in the volume rendering series basically done since January. I just have to put some finishing touches on it and write the post. I've just been very busy finishing my last semester, research, searching for a job, and considering graduate school.
I've been working on a deferred renderer and delving into screen space ambient occlusion and global illumination for one of my final projects. I'll probably post some images of the final result when it's done.
Ysaneya has a very interesting post on deferred rendering and instant radiosity.
Also, if you haven't noticed, the DirectX team has a new blog: http://blogs.msdn.com/DirectX/
