Whitted Ray Tracing and Beyond

Due: November 8, 11:55pm

For your third programming assignment you will implement:

1. Support for area lights.
   See Ray Tracing from the Ground Up Chapter 18 Area Lights

2. Rendering a mirror-like object (implementing perfect specular reflection).
   See Ray Tracing from the Ground Up Chapter 24 Mirror Reflection

3. Rendering a transparent object.
   See Ray Tracing from the Ground Up Chapter 27 Simple Transparency

Hand-in

You will hand in your code and 3 images:

• One rendering of a scene with an area light that shows soft shadows.
• One rendering of a transparent object like a glass sphere….include enough of a scene to show it is transparent.
• One rendering of a mirror-like object…include enough of a scene to show that it is reflective.

You also need to write a very brief technical report

Write a paragraph that:

• provides the technical specifications of the hardware you ran on
• states which language(s) your implementaion is written in
• provides a table that shows the time and number of rays required to render each of your 3 images

Include a README.txt file in which you list all pieces of code you did not write.
This includes any libraries, source code downloaded, or source code you typed in or adapted from a listing you read.
Please use something like the following format 1. Name-Of-Piece-Of-Code URL-to-Source

Hand-in will be done on Compass.
