Lab 3: RT Lighting
Goal: The purpose of this tutorial is to introduce you the lighting model you'll implement in your ray tracer.
Action
The following images were created using different kinds of lights.
WORKING WITH A PARTNER, try to recreate the lighting in the images starting with this ray file. You will create six ray files, one for each image. Use the lights we discussed in lecture. (Only one scene requires a change in material properties.) You should start by discussing the lights in descriptive terms (eg. what do you see rather than "this image has two point lights" -- what about the lighting will help you determine what kind of lights you need). Pay particular attention to the differences in images 2 and 5 and to the differences in images 3 and 6. Include this description in the header comment of your ray file, for example,"We chose to point lights because the lighting in this scene..." When you are finished, hand in a hard-copy of each ray file, and email me a .zip file containing all 6 ray files. Include both of your last names in the name of the zip file. Also put both your names in the header comment of the ray file. If you do not complete the lab by the end of class, please complete it by class on Tuesday.
