Final #4: Monocular Depth Cues

The above screenshot was taken in Rocket World EMMS, and shows the monocular depth cue of "Size Difference." The first orb is larger than the second (the difference being highlighted with the pen tool in Photoshop), which is demonstrated three-dimensionally by being two-dimensionally larger on the screen. This is one of the elements that give the interactive world depth and a three dimensional feel.

The above screenshot was taken in Rocket World EMMS, and shows the monocular depth cue of Occlusion. The highlighted area shows the shape in the foreground is actually simply superimposed upon the shape in the background given the angle, but due to occlusion it makes the figure in the foreground actually seem closer.

The above screenshot was taken in Rocket World EMMS, and shows the monocular depth cue of "Lighting and Shading." The highlighted area shows what is the precipice of a canyon, which would not be evident were there not different shading along the edge. The dark shading shows that the sun is not hitting that area, which gives the appearance of a shadow casting down into a canyon.


The above screenshots were taken in Rocket World EMMS, and shows the monocular depth cue of "Textural Density." Within the two figures you see the same building, which appears to be made out of wood (highlighted in red). From afar the lines in the "wood" are much closer together, but as one gets nearer the lines get further apart, giving the illusion of distance.

The above screenshot was taken in Rocket World EMMS, and shows the monocular depth cue of "Linear Perspective." The yellow line (highlighted in red) that is used to show the median in the road becomes blurrier and blurrier the further away it is supposed to be. This allows for the eye to perceive the distance, rather than simply seeing a thick yellow line running up the screen.

The above screenshot was taken in Rocket World EMMS, and shows the monocular depth cue of "Atmospheric Perspective." The two areas highlighted above depict two signs, the one on the left meant to be further away, and the one on the right closer. The one on the right is crisp and can be easily read, whereas the one on the left is blurrier and requires a significant amount of focus to read. This allows the virtual world to mimic reality.



This was a study in Monocular Depth Cues that provide a three dimensional sense to two dimensional areas. It is a final exercise from the Immersive Education course that I am taking at Boston College. The course is called Discovering Computer Graphics.

Class 10 Assignment 4

Exploring Wonderland with the generic Avatar.

Experimenting with the text box and chat features within Wonderland.

Attempting to go through the arches in Wonderland (which are evidently hollow despite their appearance.

Modifying my avatar in Wonderland, electing to change the hair style.

Changing the head shape in Wonderland.


In the two above pictures I elected to change the clothing of my Avatar in Wonderland. I decided to give him a polo shirt, suit jacket, slacks, and cowboy boots out of several options within each article of clothing.

Exploring the boundaries of Wonderland, which does not seem to be nearly as large as Rocketworld EMMS. I was only able to access a small area around what appeared to be some sort of villa.

Class 10 Assignment 1

This is a screen shot of the information section of http://TheEducationGrid.org/ highlighting the three major benefits which are that it is "Open 
source," "Royalty Free," and "Openly distributable." 

This is also a screen shot of the information section of http://TheEducationGrid.org/, stating the potential liabilities a younger student might incur, given 
the free nature of the program.


This is a screen shot discussing the security aspect that The Education Grid can offer, specifically the ability for schools to host their own servers and restrict access to those servers. It also discusses the ability for certain servers to allow for broad access, which allows anyone from a specific demographic to access the server.
