Industry and Simulation >> 3D printing failures shared online
(added 20/08/2013)
Seven catastropic failures are visually depicted by this BBC article. Each failure accompanied by blurb explaining what it was supposed to be, as well as where, and more imprtantly why it went wrong. It serves as a good reminder of how young this technology still is, and how frustrating it can be, for even expert users to produce 3D printed objects successfully with the way things currently stand.

A BBC article looking at the rise of the smart car – AI driven cars that will soon be able to communicate with cloud services for traffic control, communicate with the humans on board, and work in flocks to drive themselves with consideration (and a degree of literal mind-reading) of each other's positions and goals.

Site News: posted: 02/06/2014 Overdue Category Addition

The resource listing for Computer Aided Manufacture (CAM) has been added to the resource menu under the Industry tab. Created a while ago because of the increasing frequency of news stories on 3D printing, this listing has now been fleshed out with multiple sub-sections for a variety of CAM methods, with a focus on connecting various CAM methods up to either a pre-existing VR platform, or your own such. As per normal with a new category, it joins us with a smattering of resources already in place, with new ones to be added as they are written.

Latest Term: Physically Based Rendering

Physically Based Rendering or PBR is a method of governing how the lighting interacts with a virtual environment. More specifically it is an umbrella term for a wide variety of shading schemes, all of which take into account not just the raytracing (or raycasting) of beams of light from every light source in the environment, but also the properties the materials in that environment would actually have.

In other words it takes into account what materials the textures on objects are supposed to represent, and checks to see how that material would affect a natural light beam striking it, modifying the light ray accordingly. In other words it combines diffuse and specular lighting into a single system, balancing different levels of both, according to the material encountered. This is done by making every surface reflective as a given, and then controlling how much reflection to create according to what the local database has to say about the material properties of the textures used, or even the material properties of whole objects.

Textures that would normally be considered lit by diffusion, become blurred reflections with a percentage of the light simply absorbed. As the material becomes more shiny, so the reflection becomes increasingly more perfect by stages, with less and less absorption taking place.

Understandably, PBR methods are much more computationally intensive than a simple raytrace or raycast lighting system, neither of which could themselves be described as particularly lightweight. However, because they are a single system that mimics the effects of both a diffuse and specular lighting system in one, more simple system, the effect is you are practically halving the amount of work your lighting system has to do to create realistic results, and those results certainly speak for themselves in the sheer levels of realism created.

For interactive virtual environments, PBR is still possible despite the processor overhead, so long as you are not assessing the material each polygon face is showing in real-time. Whilst real-time assessing of how a user has just reskinned an object mid-session by adding a wooden texture manually where a metal one was before, is not going to be possible with current PBR methods, a pre-rendered environment is certainly much more workable.

Augmenting Surgery >> Improving Robotic Surgery by integrating Augmented Reality Elements
(added 31/03/2014)
Robotic surgical procedures are carried out with the aid of a camera system attached alongside the tools on the robotic arm that is inserted into the body of a patient. A surgeon carries out the operation by seeing through the camera's eye. As such, augmented reality systems have always seemed a good fit to overlay a virtual representation of the patient's innards, along with the full size and shape of the target area, on the display screen. However, the difficulty of AR object recognition inside the body has always proven too much of a hurdle. Until now.


Artificial Intelligence >> Simple Yet Highly Effective Robotic Boost to Mass Spectrometry
(added 30/03/2014)
A group of biochemists at Georgia Tech had a dream; a dream of being able to automate the process of gathering samples for mass spectrometry. A dream whereby they could just hand the analysis tool a sample. It didn't matter what colour, shape, size, density, or anything it was. The tool would take over and just know how best to approach the problem of obtaining the sample. A nice pipe dream... until the College of Computing at the same university got wind of it.


Artificial Intelligence >> Robotic Insect: Guided by the Same stimuli
(added 09/03/2014)
For an insect, it is rather large. Six inches in length, and rolling around on tank treds rather than walking. Yet, this German robot is the same as an insect where it counts - in the brain. It possesses an embodied needs-based AI, itself running on a simplified version of the insect brain, and responds to stimuli from the world around it in the self same way a natural insect would.


Artificial Muscles >> Artificial Muscle from Fishing Line: Powerful yet Cheap
(added 04/03/2014)
When we think of artificial muscles, we tend to think of new materials that allow constructs to replicate the function of organic muscles in useful ways. We don't tend to think of existing materials in common usage as a means to create these muscles. After all if they are in common usage, they would already have been tested and discarded, right?


Avatars and Personification >> Only A Few Basic Emotional Expressions are the Root of All Others
(added 02/03/2014)
We have known for some time that different cultures perceive different facial expressions as conveying different emotional states, and likewise in different cultures different facial expressions are made. Rather than having ream after ream of options for facial expression sequence files, might there be a far better way to handle such regional differences in recognising avatar-based visual emotional states?


Neuroprosthetics >> The Human Brain has a Network Backbone
(added 18/02/2014)
An unexpected discovery of a hierarchical networking scaffold inside the human brain itself, has interesting implications for future neuroprosthetics. Rather than having to interface with the grey matter right where computations are being done, we may in fact only have to interface with the white matter 'between departments' as it were, to achieve the same interface effect.

Embodied Avatars >> Futureworld
(added 16/04/2010)
Futureworld is the sequel to Westworld, yet it takes an entirely different direction. Meant to be the film that spun the Westworld franchise into an anthology set, instead it was the film that buried it. Futureworld has some great ideas, and like many films of the era, is a goldmine of nuggets concerning robotic technology, virtual reality, augmented reality and social implications.


Pure Research >> Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos
(added 25/03/2010)
Programming the Universe is a Simulation Argument book. Lloyd, a professor at MIT, works in the vanguard of research in quantum computing: using the quantum mechanical properties of atoms as a computer. He contends that the universe itself is one big quantum computer producing what we see around us, and ourselves, as it runs a cosmic program.


Pure Research >> Decoding Reality: The Universe as Quantum Information

Decoding Reality is very much a Simulation Argument book. In its pages, physicist Vlatko Vedral argues that we should regard the entire universe as a gigantic quantum computer.


Teaching and Training via VR >> Women and Gaming: The Sims and 21st Century Learning
(added 21/02/2010)
Video games have become both big business and a technological focal point for new forms of learning. Today games are not just played; players engage in game design, write fan fiction, and organise themselves into collaborative learning communities. In these communities players acquire 21st century skills in technology, but, in the best of these communities, they hone these technical skills and strengthen emotional and social intelligence.
