What We Will Be Doing This Quarter

The goals of this course are to leave you "career-ready" (i.e., both work-ready and research-ready) for tasks, both GPU and RenderMan, that require the implementation of graphics algorithms in the form of shaders.

You will have access to the graphics systems in OSU's Computer Graphics Education Lab (CGEL) in Batcheller Hall 244. This is likely the only place around OSU where you can get access to RenderMan. It is also a place to get access to the OpenGL Shading Language (GLSL), although you probably have it if you've bought a good graphics card in the last 2-3 years.

Speaking of graphics cards, you can tell if a card will support vertex and fragment shaders by looking for the phrase Shader Model 3.0 compliant in its specifications. A card will support vertex, fragment, and geometry shaders if it is Shader Model 4.0 compliant. Some of the very-new cards will be Shader Model 5.0 compliant. This means that they will also support tessellation shaders.

CS 519 topics include:



Prerequisites

You must come in being a good OpenGL programmer. This is not a good time to learn computer graphics and OpenGL for the first time.

CS 450/550, 419/553, or 554 are acceptable preparation. CS 419G is adequate preparation if you looked at and understood the graphics programs we used.

Learning Objectives

On completion of the course, students will have demonstrated the ability to:

  1. Explain the difference between Model Coordinates, World Coordinates, Eye Coordinates, Clip Coordinates, Normalized Device Coordinates, and Screen Coordinates.
  2. Explain the ModelView and Projection matrices, and what operations belong in each, and why.
  3. Describe where surface, displacement, vertex, fragment, geometry, and tessellation shaders fit into the graphics pipeline
  4. Explain the difference between uniform, varying, and attribute variables.
  5. Apply the concept of octave noise to shader effects.
  6. Explain the difference between bump-mapping and displacement-mapping.
  7. Demontrate how to use cube mapping to achieve a good approximation to reflection and refraction. Explain what is different about reflection and refraction done this way and real reflection and refraction.
  8. Apply shaders to visualization problems
  9. Use textures in shaders for imaging and general data.
  10. Explain how to avoid the aliasing effects of sharp transitions.
  11. Demonstrate how shaders can be used to simulate various optics effects.

The Virtual Hand Raise (VHR)

I recognize that it sometimes takes a certain amount of courage to ask a question in class. But, the worst thing of all is to not ask! So, this class also offers a feature called the Virtual Hand Raise. Click here to get into it. It will allow you to send me a question or comment, completely anonymously. I will answer questions submitted this way by email to the class or in class.



Textbook

You are expected to have the following book handy:

Bailey and Cunningham, Graphics Shaders: Theory and Practice, Second Edition, CRC Press, 2012. ISBN: 978-1-56881-434-6.

This is available through Amazon or through CRC Press.

There will be assigned readings from it. You don't need your own copy, but at least have one you can share. There is one in the CGEL "library", but chained to a bookshelf is a tough way to read a book.

Other course material will consist of web pages, handouts, and notes taken in class.



Other Good References

The Rost, Upstill, and Shreiner books are in the "CGEL Library".

Project Turn-In Procedures


Bonus Days and Late Assignments

Projects are due at 23:59:59 on the listed due date, with the following exception:

Each of you has been granted five Bonus Days, which are no-questions-asked one-day extensions which may be applied to any project, subject to the following rules:

  1. No more than 3 Bonus Days may be applied to any one project
  2. Bonus Days cannot be applied to tests
  3. Bonus Days cannot be applied such that they extend a project due date past the start of Test #2.

Click here to get a copy of the Bonus Day Submission Form. Fill this out and turn it in the next class period after turning in your project.

After the due date, after you have exhausted all your eligible Bonus Days, projects can still be turned in for 50% credit, as long as you turn them in within two weeks of the original due date. You still need to turn in your paper bundle. (That's how I will know to go look for your project in the turn-in area.)



Grading

Grades will be posted through this web page. To protect your privacy, they will be posted by your alias that you give me in Project #1.

Click here to see the current grade posting.

CS 519 will be graded on a fill-the-bucket basis. There will be 8 projects and two tests. You get to keep all the points you earn.

Your final grade will be based on your overall class point total. Based on an available point total of 1040, grade cutoffs will be no higher than:

Executables

These executables are all loaded on the CGEL machines, but you can also get them here in case (1) you want to run them on other machines, or (2) there are newer versions than what are on the CGEL machines.

  1. noisegraph.exe
  2. glman.exe

The bvrman executable is not included here because it looks for a local copy of RenderMan in order to work. Unless you have renderMan installed on your own computer, you will need to do the RenderMan work in the CGEL.

You might also need these dlls:

  1. glew32.dll
  2. glut32.dll
  3. msvcr71d.dll



Class Rules



Students With Disabilities

Accommodations are collaborative efforts between students, faculty and Disability Access Services (DAS). Students with accommodations approved through DAS are responsible for contacting the faculty member in charge of the course prior to or during the first week of the term to discuss accommodations. Students who believe they are eligible for accommodations but who have not yet obtained approval through DAS should contact DAS immediately at 737-4098.
