Theory and practice of perception of 3D depth (cont.).

It is believed by the author that the perception of 3D depth in human vision is made possible by the unusual distribution of cones in the retinae, together with the complete lack of correction for chromatic aberration in the dioptrics of the eyes. Together, as discussed & demonstrated in the section on retinal interactions, these lead to what has been termed the widescale receptive field which has a resolution believed to be around 27 - 30 times lower than that of the primary, midget receptive field.

In addition, the driving forces for this low resolution receptive field are essentially (R+G) & B (or Y & B where Y equates to (R+G)). As such they turn out to be extremely well-appointed to work well in generating 3D perception when driven by the BY anaglyph image data as provided in recent years by the Colorcode3D form of anaglyph presentation via amber & deep blue filter glasses.

Alternate methods of providing perception of 3D via shutter glasses or polaroid glasses have been shown to be practical, but have the need for special glasses. As such they are discussed together with various anaglyph forms of visual presentation in the report Theory and practice of general perception of 3D relative depth - 2011 update.pdf to be found with other downloadable reports.
