A Slower Speed of Light: Developing intuition about special relativity with games

Gerd Kortemeyer, Philip Tan, Steven Schirra
2013 International Conference on Foundations of Digital Games  
In this paper, we introduce A Slower Speed of Light, a game by the MIT Game Lab to help students understand and visualize these complex phenomena by artificially lowering the speed of light to walking  ...  The effects of special relativity are not immediately observable in our everyday lives, so we tend to lack an intuition about them.  ...  OpenRelativity provides the public (and, in particular, game designers) with a set of tools for simulating the effects of traveling near the speed of light, demonstrated by A Slower Speed of Light.  ...

Introduction to real-time shading with many lights

Ola Olsson
2014 SIGGRAPH Asia 2014 Courses on - SA '14  
Thus, efficient real-time shading with many lights, represents a potential for solving many of the problems facing the development of next generation high-end games.  ...  The course combines production experience from game developers with the latest research into efficient many-light algorithms for both desktop and mobile hardware.  ...  Both are very similar -in fact, you could consider tiling to be a special case of clustering with just a single depth slice.  ...

Visual search under scotopic lighting conditions

Vivian C. Paulun, Alexander C. Schütz, Melchi M. Michel, Wilson S. Geisler, Karl R. Gegenfurtner
2015 Vision Research  
Scotopic contrast sensitivity is significantly lower overall, with a functional scotoma in the fovea.  ...  When we search for visual targets in a cluttered background we systematically move our eyes around to bring different regions of the scene into foveal view.  ...  This could either mean that eye movements are used to bring these images onto the peripheral part of the retina with the highest visibility for a given target (e.g., the development of a pseudo fovea)  ...
