Electronic submission system for CS 248 assignment 4

by Apostolos "Toli" Lerios

Instructions for using the submit program

1. Log on an elaine (not a raptor).

2. Place one image for each of the shaders you wrote in your WWW directory.
   • Save the image as a PPM image
   • View this image with xv
   • Save the image as a TIFF format image, using LZW compression
   • Put this TIFF image in your ~/WWW directory
   • Remove the PPM image to save space.
3. Place the following files in your work directory:
   • shader.c
   • a README file, which details how your shaders work, what parameters you defined and what they mean
   • Any ppm images for textures, bump maps, etc., that you used to make the final images above.
   • The .cfg files used to create each image, so we can reproduce your work.

4. cd to your work directory, i.e. cd within your work directory.

5. Execute the submit program by typing

   /usr/class/cs248/assignments/assignment4/submit
   

   Just follow the on-line instructions from then on.

   If you encounter an error due to insufficient disk space, then try the following, in order:

   • Go to step 1, and try submitting using another elaine.
   • Make sure your work directory contains only the files we ask you to submit: no huge temporary image files, subdirectories, or whatnot.

After you submit your work: a short FAQ

1. What does submit do to my account?

   submit just packages the contents of your work directory and mails them to our account. It doesn't change any file or directory permissions.

2. I made a few last-minute changes. Can I execute submit again?

   You should normally execute submit just once, after you are 100% sure you are done with your assignment. If there is a catastrophe, and you end up executing it twice (or heaven forbid thrice!), we will only take into account your most recent submission, ignoring all previous ones automatically. But please avoid multiple submissions!

3. How do I know whether submit completed successfully?

   Unlike other submission programs you may have used, submit does not send out an e-mail message notifying you of successful completion of the submission process. submit has done its job if it has executed without any errors.

4. Do I need to keep around my personal copy of the work directory after submitting?

   You may clean up your account, and eliminate all assignment-related files, anytime after submitting your work. However, we strongly suggest that you do not do so before the end of the quarter.
