Perspective Correct Smooth-Shadow
A perspective correct smooth shadow is one which emulates physical shadows to a high degree. Additional processing is performed on the shadow, increasing its size as it gets further from the item it is the shadow of. At the same time the degree of anti-aliasing around the edges, expands into a general fuzziness, interlacing over the main shadow. If the distance is great enough, the distorted shadow begins to fade out or lessen.

Typically in VR, when we model erosive forces, we think of the smoothing effect of water. We think of smooth stones, smooth edges, and smooth cavities. We don't typically think of sharp edges and triangles. That may be a mistake.
Endgame: Singularity is a single player game, developed to give a little taste of the perspective of a singularity event from the perspective of the emerging, embryonic AI. It skips over more than a few steps on its way out, but is still a unique perspective on the singularity, worthy of a look.
Idoru is, essentially, one long piece on the struggle to understand the quest for robot rights ? or in this case, the rights of an AI itself, from an outsider?s perspective; from the perspective of one who refuses to accept the AI as other than a tool, despite all evidence to the contrary.
Michael Heim, the author of this book, describes modern 'VR' as a pale imitation of real VR. On this point, he is of course, all too correct. He then goes on to state that the real thing is fast approaching. We'll soon be able to totally immerse ourselves in detail-rich, highly interactive artificial worlds....
A coder?s article about creating realistic, dynamic soft shadow in real-time interactive, and complex scenes.
Zebrafish are handy little critters, as far as neuroscience goes. These tiny, mostly transparent little fish have brains that whilst greatly simplified, have a structure remarkably similar in basic form, to our own. Add in that aforementioned near-transparency, and it becomes possible under the correct lighting conditions, to literally see right into their brains, to the point where you can practically watch as a thought takes place.
A quote from "Otherland: City of golden shadow", talking about the probable confusion that could result from a realistic enough, surround news feed versus actual physical experience of a disaster.
For a great many, the dream of being graceful and smooth of movement - or even not scattering every item on a desk they try to lean over - is something of a fondly held dream. For others, even being able to walk unaided holds a similar place of reverence.
A lengthy quote from the book "Otherland: City of Golden Shadow", by Tad Williams, which sums up the dialectic between physical reality and virtual reality, in one of the most succinct and apt ways we have encountered.
Read this series for the twisting, evolving, many diverse threaded storyline, or read them for the wonderful imagery, and enchanting ideas for VR of the future. Whichever reason makes you pick up one of these, you are in for one hell of a ride!
