RT Lighting
The purpose of this tutorial is to introduce you
the lighting model you'll implement in your ray tracer.
Pre-lecture
The following images were created using different kinds of lights.
Working with a partner, describe the light in each scene. Try to come up with a "model" for the lights used. (Pay particular
attention to the differences in images 2 and 5 and to the differences in images 3 and 6.)
Post-lecture
Try to recreate the lighting in the above images starting with this ray file.
Use the lights we discussed in lecture. (Only one scene requires a change in material properties.)
