3501 #5: Screen-Space Effects

Assignment 5: Screen-Space Effects

Due date: Wednesday, Nov 10

This assignment will help you to get a bit of practice implementing and using image processing operations. It is also a chance to use your creativity, possibly designing an effect you were hoping to include in your project.

Part 1: setup

Download the camera demo from the 3501 site, if you didn't get it before.
Run it to make sure it works before starting to modify it.
Look carefully at the image.fx file, which contains a few example screen-space effects. Try out one of the different effects.

Part 2: Transmission error

Implement a "transmission error" effect. The error should be mild, so 90% of the screen should be unaffected, but the remaining 10% should be distorted. The error region should move from the top of the screen to the bottom over time while not increasing in size.

Part 3: Your own effect

Invent your own effect and implement it. For full marks, the effect should do the following:

Be visually interesting (write a comment arguing why your shader holds some visual interest)
Be original (i.e., do not reimplement some shader that you find a tutorial for -- imitating an existing visual effect is OK, though, just don't also imitate the implementation)
Use a neighborhood operation of some sort

Handing it in

Hand in your project using WebCT. The easiest thing to do is to create a single zipped folder and submit that, rather than all the individual files. It might take a while to upload, so be prepared to take a little break while the files are in transit.
