Radiance / Sampling

The first part of this assignment was to download Radiance and create a few simple images and an animation. The image at right is a full size rendering of the box I created. I tried to model this box off of previous renderings I have done with a similar Open Inventor box using IVTrace. The box took about 5 minutes to render using one MIPS R12000 Processor on an SGI (?Origin 2000?). I also created an animation of the light gradually being increased. It has slightly less quality and only took about 2 minutes per frame (with 50 frames) on the same machine.

The second part of the assignment was to create a small Open Inventor program to randomly sample points on a sphere and set each points emissive color intensity based on the

vOut.N


where vOut is the direction from the sample to the camera position and N is the surface normal at the point.

I wrote this code using the SoQt library provided by Coin3D. In addition, I used autoconf and automake to generate a configure script for portablility. The code has been tested on Redhat Linux and IRIX.
