Technical Artist Summit: Better Computer Graphics through Understanding of Human Visual System


Computer graphics used by computer games continues to make significant advances. From modest beginnings in the 80s and 90s we have reached the point where we simulate and display complex light-matter, optical, motion and physics interactions. As hardware and techniques used become more sophisticated, we must also pay more attention to how generated visuals are to be perceived and interpreted by human visual system. It is important for several reasons: Human visual system, while effective, is not technically accurate and may lead to misperceptions of hues, light intensities, sizes and shapes as well as general attentional misperceptions. Understanding human visual system better may help alleviating these issues but also to help developing more computationally efficient algorithms that maximize what is important for human vision and minimize what is less likely to be perceived. The talk will overview the modern understanding of human visual system, such as hue, intensity, shape and motion perception and discuss specific implication on camera design, anti-aliasing, lighting and global illumination techniques.
