Glimpses—The Uncanny Valley Why are monster-movie zombies so horrifying and talking animals so fascinating? Written and illustrated by Dave Bryant Japanese roboticist Doctor Masahiro Mori is not exactly a household name—but, for the speculative fiction community at least, he could prove to be an important one. The reason why can be summed up in a simple, strangely elegant phrase that translates into English as “the uncanny valley”. Though originally intended to provide an insight into human psychological reaction to robotic design, the concept expressed by this phrase is equally applicable to interactions with nearly any nonhuman entity. Stated simply, the idea is that if one were to plot emotional response against similarity to human appearance and movement, the curve is not a sure, steady upward trend. The same factors that inspired Doctor Mori to research and describe the uncanny valley and the rest of the curve to which it belongs are of immediate concern to any creator of fantasy or science fiction.

PHILIPK.NET Tutorial by Philip Klevestav < Back to Tutorials Index page First of all, this tutorial is going through some general ideas and hints rather than go indepth on howto create a specific set of models. I have split up the tutorial into sections where I try to give you some ideas on what I think about and avoid when I work with modular units. Do keep in mind that the examples here are extremely basic geometry and texture wise, I did this on purpose to be able to show off different ideas better. So, first of all start with the absolute first basics: What type of set will you create? There are a lot of things to think about when it comes to usability of modular sets. If we go right to my super ultra basic example here which happens to be a sci-fi wall panel. I built a very simple highpoly of that part. These are the two shapes I will base the whole set on. The red shape here is 32x128 units and the yellow 64x128 units large. Same goes with decals, such as the letters and numbers here.
Portable Network Graphics (PNG) Specification (Second Edition) Abstract This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. This specification defines an Internet Media Type image/png. Status of this document This section describes the status of this document at the time of its publication. This document is the 14 October 2003 W3C Recommendation of the PNG specification, second edition. This International Standard is strongly based on the W3C Recommendation 'PNG Specification Version 1.0' which was reviewed by W3C members, approved as a W3C Recommendation and published in October 1996.

L'AR.Drone de Parrot : un jouet pour adultes ? Parrot a présenté hier soir son AR.Drone, un quadricoptère pilotable via l'iPhone ou l'iPod touch grâce à une connexion WiFi ad-hoc. Léger – 400 grammes en mode intérieur, 360 grammes en mode extérieur – et d'une taille d'environ 50 centimètres, l'AR.Drone intègre deux caméras : l'une frontale, VGA et grand angle, de 640 x 480 pixels, qui permet de voir ce qu'il se passe à l'avant de l'appareil, et l'autre verticale, QCIF, d'une résolution de 176 x 144 pixels, qui permet de visionner ce qui se passe en-dessous. La vidéo est envoyée en streaming à l'iPhone ou à l'iPod touch : ces derniers intègrent alors des commandes tactiles qui permettent de piloter l'AR.Drone. Un jouet de luxe L'AR.Drone a été présenté par le PDG de Parrot Henri Seydoux comme étant la réunion du jeu vidéo et des modèles radiocommandés. Des performances réelles… …Et quelques défauts Autres points à prendre en compte : les 4 hélices produisent un vent conséquent et un bruit non négligeable.
Welcome — Interactive Ray Tracing Real-Time Ray Tracing Realization. SSE Optimization Introduction Today we will examine an original graphics engine for computer games which is based on the ray tracing technique and which differs completely from others used in modern popular 3D games. The engine doesn't (!) We will speak about its unique possibilities and principles of operation, consider aspects of optimization of applications for SIMD extensions, and first of all, for SSE - an additional set of processor instructions first realized in Pentium III and Celeron II. What for? Why we create one more engine if there are a lot of them? It is OK if you are going just to practice shooting for a couple of hours. All such features must be supported by a graphics engine. To be drawn, large levels are calculated beforehand during a long period of time and then the recorded information is used. The problem is not only in visibility. Let's approach the problem from another point of view. What? Shadowcast is a demo program from NVidia. Ray tracing speed VirtualRay engine Performance
Rising Sun Pictures We are thrilled that Gravity won so many Oscars at the 86th Academy Awards, including the Visual Effects category, to Tim Webber, Chris Lawrence, David Shirk and Neil Corbould. RSP created the climactic re-entry sequence, and are honoured to have the work acknowledged as the year's best. As we enter 2014, we're busy on a number of high profile projects, yet to be announced, along with our ongoing role on X-Men: Days of Future Past. Our venture into long form production continues with "Deadline Gallipoli", produced by Matchbox Pictures and Sam Worthington's Fullclip. The First World War drama commences shooting in the coming months and we are working with the team on the most efficient way to plan and realise the effects for the miniseries. Australia remains a world-class destination for shooting and post, and the continuing fall of the Australian dollar brings greater value to productions who choose to work here. Tony Clark and the team at RSP

Introduction So I'm back from I3D (papers links at which was a very good time. There was one ray-tracing related paper at I3D: "Interactive k-D Tree GPU Raytracing". Speaking of ray tracing, the second Symposium on Interactive Ray Tracing, aka RT07, will be September 10-12, 2007 at Ulm University, Germany. On to the articles.
ACM Transactions on Graphics Sunflow Global Illumination Rendering System FAQ This document answers Frequently Asked Questions about the Sunflow Global Illumination Rendering System. It also provides numerous performance tips as well as more detailed explanations of how certain features of the renderer work. Most of this information comes directly from Christopher Kulla, the creator of Sunflow. The faq is comprised of his email and forum-post replies, with some contributions from others as well. Tuning Ambient Occlusion (AO) The options inside the shader block should be self-explanatory. Tuning Instant Global Illumination (IGI) IGI is highly sensitive to the input values: gi { type igi samples 128 % number of virtual photons per set sets 1 % number of sets (increase this to translate shadow boundaries into noise) b 0.01 % bias - decrease this values until bright spots disappear bias-samples 0 % set this >0 to make the algorithm unbiased} Here's how to quickly tweak these values: 1. The important thing is to set the bias value properly. 2. Tuning Irradiance Caching 1.
