Book

Recommended

Peter Shirley et al., "Fundamentals of Computer Graphics", 2nd or later edition, AK Peters 2005 [Errata]

Optional

Useful book on geometry, ray intersections, transformations etc.
Philip Schneider and David Eberly, "Geometric Tools for Computer Graphics", Morgan Kaufmann 2002

More advanced text on global illumination and photon mapping
Henrik Wann Jensen, "Realistic Image Synthesis Using Photon Mapping, AK Peters, 2001

Slightly dated, but still a very comprehensive overview of image synthesis
Andrew Glassner, "Principles of digital image synthesis", Morgan Kaufmann, 1995

Course Objective

This course will cover the basic algorithms used for computer graphics rendering. During the course a ray tracing program will be implemented. This program will include acceleration structures, and advanced rendering capabilities such as Monte Carlo ray tracing and photon mapping. At the end of the course the students should be able to write a ray tracer, able to handle different types of geometry efficiently, capable of choosing good acceleration structures, have basic knowledge of shading models such as the Lambert and Phong models, knowledge of texture and bump mapping techniques (possibly mipmap filtering), basic knowledge of sampling and filtering, global illumination and photon mapping, and an idea of more advanced topics such as programmable graphics hardware.

Contents

The ray tracing algorithm, camera models, geometry intersection, geometry tessellation, acceleration structures, shading models, texturing, bump mapping, sampling and filtering, and a brief introduction to advanced topics such as Monte Carlo ray tracing.

Grading

This is class is for 4 units. There are 4 programming assignments worth 55 points of the total grade. There are two exams worth 30 points of the total grade. The total is 85 points.

Assignments

You are free to choose the language and platform to implement them, but C++ is recommended for its object oriented features and speed. You might want to take advantage of any speed optimizations available in your chosen environment. (Compiler optimizations, OpenMP, OpenCL, SSE, AVX, CUDA for NVidia cards, etc are a few possibilities)

Project 1 (12 points) - Basic Ray Tracer - Due 4/11
- Assignment: docx pdf
- Sample Code
- Test image
- Test image small
- Sample Extra Credit Image

Project 2 (12 points) - Spatial Data Structures - Due 4/25
- Assignment: docx pdf
- Dragon.ply file
- Test image - Updated with correct brightness
- Extra Credit Image
- Update: You only need to implement 2 of the following for extra credit; Antialiasing, Area lights, and Fresnel dielectrics and metals

Project 3 (12 points) - Materials and Textures - Due 5/14 (extended)
- Assignment: pdf
- Dragon.ply file
- Test image

Projects are due before class in EBU3 basement lab (10am-11:50am) on the due date, or speak to the instructor for submission directly after class.
5 points are deducted for a late submission the following week after the due date.
10 points are deducted for a late submission after 1 week after the due date.

Final Project (19 points) - Due at presention during Finals Week
- Assignment: Render a Scene or your choice with a complex feature as discussed in class (and the slides).
- Make a website describing your final project and the process it took to create your final render. This website should discuss your goals, show intermediate steps and images, and your final image. Please provide a single zip file with a single .html file that contains your website along with any images that you wish to use for your website. Do not include images that you aren't shown on the website, and make sure all images are linked to the relative paths you set them. We will post your final projects here. Please email them to Matteo using the address above. (and feel free to post them on your own service and send a link, instead)
