Advanced Rendering: Assignment #0

My Ray Tracer:

Presentation #2 Topic

The topic of my second presentation will be the following paper:

Effects of animation, user-controlled interactions, and multiple static views in understanding 3D structures

Assignment #2

For this assignment, I attempted to recreate the work done the paper "A Model of Visual Adaptation for Realistic Image Synthesis" by Ferwerda et al. The paper was presented at SIGGRAPH 1996. Using the images provided by Professor Ferwerda, I tried to recreate the images from the paper. While I was able to make some images, I am not sure that they are correct. I found the paper a little hard to follow and understand exactly what was done by the authors. Anyway the following are my results are various luminance values.

Lw = 10

Lw = 50

Lw = 75

Lw = 100

Lw = 200

Lw = 1000

Presentation #1 Topic

My topic for presentation #1 will be on using cartoon animation techniques in physically based animations to improve user accuracy, attention, and appeal.

My resources will come from two papers as of now (more may be added as presentation is finalized).

Paper #1: Perceptual evaluation of cartoon physics: accuracy, attention and appeal

Paper #2: John Lasseter's principles of animation paper from SIGGRAPH 1987

Applied Preception Assignment #1

These are my results from assignment #1. First are the basic random dot stereograms.

This one uses the following shark depth map:

My second basic stereogram uses the valley depth map.

The corresponding depth map:

My extension was extension three, creating a more pleasing stereogram. I had some issues getting it to work. I think I can see the shark in the image but I have been having trouble seeing the hidden images, so I am not sure if I am actually seeing the image or I just assuming I'm seeing the image. My results:

The texture used to create above stereogram:

My approach was to use colors of the texture instead of random colors. The stereogram then should have a section of the texture repeated throughout the stereogram, and thus make a better looking stereogram. My results were a little off, color wise, unfortunately.

I used Matlab to create these iamges. Matlab worked fine except in one instance. The basic shark stereogram does not look quite right due to a modification that had to be made to the depth map image. The shark depth map was technically a color image. I need a grayscale image for the algorithm. I used the rgb2gray function in Matlab and I believe the conversion from the color image to the gray scale image caused some of the values to be slightly off in the depth map and affect the resulting stereogram. Luckily, the effect was minimal.
