Back-Face Culling or BFC is a standard approach taken by 3D rendering engines, to help remove unnecessary items from the render view. Essentially, as the name implies, it is the removal of all polygonal faces or rendering triangles which face away from the viewpoint. I.e., all parts of a given object that are occluded from the viewer by other parts of the same object, as they are on the ?back? relative to the observer.

This book, written by a neuroscientist, proposes that use of technology such as social networking, where computer mediation rather than face to face communication is the order of the day, actively changes how our brains process information over time.
Researchers from Germany have discovered strong evidence that with humans, picking faces out of a crowd has a lot less to do with the shape of the face, or the expression upon that face, and a lot more to do with whether the teeth are visible or not.
In a handful of the more pioneering virtual environments, a system called FaceGen, along with other, similar systems, allows a user to photograph their face from front and side, and use that to put together a 3D model of their physical head, if they so desire, to use for the basis of their avatar presence online. Other technologies are just coming into use, that allow adjustments, based on attractiveness, of that face.
Researchers at Toyohashi University of Technology have discovered that the human bain processes the colour of a face separately to the features of that face. This is an interesting development, especially when placed in the context of crafting personalised avatar forms for AI sales agents and other interactive AI in virtual space.
If you are looking for someone in a crowded scene, whether a "where's Wally" book, or a crowded cafeteria, your eyes scan the room like a roving spotlight, moving from face to face? Researchers at Researchers at MIT's Picower Institute for Learning and Memory have found that you do. What's more there's something very much akin to a clock cycle controlling the speed at which you do so.
An interesting discovery has come out of a study by researchers at the Hebrew University of Jerusalem and at New York University and Princeton University. Namely, the discovery that the face is not the primary communicator of emotion. The rest of the body handles that. This is of course critical for our virtual environments and their avatars.
The concept of aging, or the appearance thereof, is a good one. It is an aspect of circumnavigating the uncanny valley that should never be forgotten: No matter how perfectly a human face, behaviour, mannerisms are recreated, unless the face, the body seems to change with time, the uncanny valley has not really been conquered.
Facial recognition systems applied to canine faces. A still from a very silly film, is not so silly after all. With other, similar projects already in the works, there is no reason in the world why face recognition cannot be applied to any animal with a face.
In the modern era of VoIP and face to face communication, we are in danger of losing the power of virtual reality in a kind of mixed reality system. For whatever reason: nationality, lisp, burr, mixed gender heritage or simply being half drunk or high at the time, the market for the voice you emit to be synthetic, to be virtual is huge, preserving the integrity of the virtual world, by keeping the purely physical out.
One of the major issues with any virtual form, is facial expression. Traditionally, getting a virtual face to match your physical intent for expression in real-time, was a lost cause. Even for big budget film making, CG overlays had to be constructed frame by frame by hand. Enormously time consuming, ludicrously expensive and completely useless for real-time usage.
