Photorealistic rendering has the goal of rendering an image as a real camera would capture it. While this is already an ambitious goal, for certain scenarios you might want to take it further: render an image as the human eye would capture it or even as the human being would perceive it. You could call it visiorealistic or perceptiorealistic rendering, but if anyone could come up with a catchier term (or tell me that there is one already in existence) I'd appreciate that.Here are some examples to make my point clear. When you take a picture with a camera at a low illumination level, you either have a good lens or get a noisy image. For a human observer, scotopic vision kicks in and gives rise to the Purkinje effect (colors are shifted towards blue). This effect depends on the HDR luminance information, which are lost when I display the image on a LDR display. In addition, the human brain may use depth information to 'filter' the perceived image - information which are lost in a final (non-stereo) rendering.Assembling an exhaustive list is probably an elusive goal. Could you suggest some of the effects of the eye and the brain that I would need to consider?
