Gallery Contributions

Who Can Contribute to the Gallery?

You must be a past or present CS488/688 student.

Note that when you make a contribution, everyone on the web can access and/or copy that information. So you should consider every contribution as a release into the public domain. If you want, you can place additional restrictions on use in your documentation. If you feel especially paranoid, you may also want to mark your image(s) with the ``annotate'' function in display to discourage illicit copying and reuse without citation.

What Can I Contribute?

Naturally, images output by a renderer are nice, but screen grabs of interactive applications are also quite welcome. Both the unique scene from your raytracer (A4) and the results of your projects are welcome. The images don't have to be the result of an assignment.

We reserve the right to refuse a contribution if it is of poor quality and/or takes too much disk space and/or is exceptionally tasteless and/or has little to do with computer graphics. Also, we obviously can't install documentation that makes it trivial for later students to do the assignments. Source code for part of an implementation of an assignment, for example, would have to be refused. MPEG animations will be accepted if short and well compressed.

Note that multiple images can also be contributed, and we don't mind extensive documentation if you can make it available in an online form (see below). Basically, within a contribution weblet you can put anything, but there should be at least one ``representative image'' which is an entry point to your work.

How Do I Make a Contribution?

1. A representative image (or images) in JPEG format.

Name the image after your userid, i.e. userid.jpg. If you have more than one image, use a number: userid0.jpg, userid1.jpg, etc. Note that a quality level of 85 may corrupt some computer graphics images. Use 90 or even 95 if you feel it's warranted.

2. A thumbnail image (or images) on the order of 100x100 in GIF format.

Use display/convert to reduce the number of colours and do good colour quantization, and properly antialias during reduction. Use the same filenames as above, but use .gif as a suffix. Try to keep as close as possible to 100x100, or 10000 pixels if your source image is not square. Smaller images are incomprehensible, but larger ones take too long to download.

3. Some background information and documentation.

This can range from a plain text description to an HTML page. You may want to include the Tcl script used to create the scene. If you use an HTML "weblet" with multiple pages, preceed each filename with your userid, i.e. userid_index.html, userid_script.gn, etc. If you use HTML, you may include links to your images, just be sure to label everything with your userid and use relative links.

4. A README file.

This file should contain your full name as you wish it to appear, the titles of (each of) your image(s), and the entry point of your documentation, if you use HTML documentation. Say whether multiple images all should point to the same documentation, different documentation, or different parts of the same documentation. The contents of this file will be used for installation, but will not be placed in the gallery.

Try to set things up so we can just plop everything in a directory and link it into the gallery. If you don't know HTML, don't worry: a 1-paragraph descriptive text passage is fine. Use a .txt suffix in this case.

Finally, email smann@uwaterloo.ca and let us know where all this stuff is. We'll grab it and email you when it's installed for posterity in the gallery.
