Then I set the camera position, the light and the material manually. To animate the light intensity and position, I wrote a python script to parse the XML scene file that I've created in the previous step and change the light position/intensity in each frame in a circular path and render each frame (total of 144 frames, 6 seconds @ 24fps) using my raytracer. You can download and test the scene file.
