Monocular Depth Cues

The following photos are 6 screenshots of monocular depth cues, which are different ways used in 2D creations (such as on the computer/web and in paintings) that give the impression of depth (distance) making the image appear the be in 3D.  They are part of a final exercise from the Immersive Education course that I am taking at Boston College. The course is called Discovering Computer Graphics. For details, visit the immersive BC portal at http://ImmersiveEducation.org/@/bc.

In this image, some of the skulls appear smaller & less clear/detailed, giving the impression that they are farther away than the larger clearer skulls. This is an example of atmospheric perspective (by being less clear and less detailed) and also an example of size differences.

In this image, the stairs that are circled seem to be very small & dense, making them appear to be far away. This is an example of texture density.

In the third image, the trees in the background are smaller, which makes them look farther away and the bigger trees look closer. This is an example of size differences.

In this image, the rocks block some of the docks and the water, giving the appearance that the rocks are in front, they also are a lighter color on the top than the bottom, giving the viewer the impression that there is a source of light. This is an example of occlusion and also of lighting and shading.

In this image, the lines on either side of the docks seem to get narrower, giving us the impression that there is distance. This is an example of linear perspective.

In the sixth image, the table blocks part of the "404 not found" structure, making it look like the table is closer. This is an example of occlusion.
