The Uncanny Valley

• "The uncanny valley hypothesis holds that when robots and other facsimiles of humans look and act almost like actual humans, it causes a response of revulsion among human observers. The "valley" in question is a dip in a proposed graph of the positivity of human reaction as a function of a robot's lifelikeness. It was introduced by Japanese roboticist Masahiro Mori in 1970." <exerpt from Wikipedia>

View-dependent texture mapping

1. Determine visible cameras for each surface element

2. Blend textures (images) depending on distance between original camera and novel viewpoint
