Workshop update

Hi All,

We are still short on registrations for the upcoming workshop, and have room for additional presentations as well. If you have been thinking about coming, Minneapolis is lovely this time of year, and we hope you can make it -- it's not too late.

To round out the talks, we've decided to hold a few tutorial sessions. One will be given by Zack Rogers of Architectural Energy Corporation on his Sensor Placement + Optimization Tool (SPOT), explaining its design and use. I plan to give a tutorial on image-based lighting, demonstrating HDR image capture, using mksources and using a captured lighting environment to illuminate synthetic objects. I may give another tutorial on rtcontrib as well, depending on time constraints.
