In September, 2013 I gave a presentation at the 5th Vermont Code Camp on using Monocular Cues in 2D Games to create the illusion of depth. The presentation is available on SlideShare. A couple sample videos used during the presentation are shown below.
Perspective: Horizon Line
Parallax in X and Y planes
Presentation Description
Gain a new perspective on old concepts by applying the study of monocular cues to visual depth in 2D game development. The presentation looks at the familiar topics like perspective and parallax, reviews their use in games and traditional animation, then explores ways programs might aid artists in the application of additional monocular cues to strengthen the player’s perception of depth.
