Class 2, Assignment 3 : Six Monocular Depth Cues

Pictured above is an example of the Size Differences Monocular Depth Cue use to help illustrate the 3D environment.  The chair closest to the avatar appears larger than the chairs in the background, though all the chairs are the same exact model and possess the same dimensions if the avatar was to approach each one individually.

The Occlusion Monocular Depth Cue helps establish a 3D environment by placing objects in front of others.   This aids the user in determining object's relative positions to one another.  The tents above all occlude each other moving down the line.

Lighting and Shading is illustrated on the crates above.  The light source for this image exists above and to the left of the avatar.  This causes the left side of the boxes to be brighter than the foreground surface.  This aids the eye in determining the 3D shape of the crates.

Texture Density is shown above using the floor pattern of this environment.  In the foreground one can see the varied colors and textures of the floor.  Towards the far end of the hall the colors and textures become more dense, thus losing the detail until eventually you can only see the gray color.

Linear Perspective is illustrated above in a classic example of railroad tracks in this metro station environment.  The lines of the tracks are parrellel to our line of sight and seemingly recede in the distance.  If the subway car wasn't blocking the end of the tracks one might be able to the tracks "converge" at vanishing point.  

The Atmospheric Monocular Depth Cue is illustrated above by the rusty chandeliers in this environment.  The chandelier in the foreground is highly detailed, allowing a user to determine the materials and condition of the fixture.  The chandelier in the background is depicted simply as a gray shape in the distance, despite being the same exact model.  This is due to the distance the light must travel from the far end of the hall.  In real life, atmospheric particles and environmental effects would affect the light's direct path to our eyes, resulting in the above effect.  Objects in the foreground are sharper and more detailed, while objects at a distance are less detailed and sometimes fuzzy.
