+ - Try real-time GPU-based stereoscopic raytracing at home->

Submitted by
descubes
descubes writes "GPUs are powerful enough to do real-time ray-tracing nowadays, at least for simple scenes. Getting a 3D TV is really easy these days. So why not combine the two? In this demo, Taodyne demonstrates a simple real-time ray-traced scene, how you can interact with it, and how you can use it to render real 3D on stereoscopic displays. With sufficient GPU power, this technique even works on glasses-free 3D displays. And of course, you can use a number of other GPU tricks, like shaders from ShaderToy to add a little life to your slide elements. This is all based on freely downloadable software and widely available hardware, so you can try this at home now."

+ - Live coding: A 3D DNA strand->

Submitted by
descubes
descubes writes "Old timers may remember Logo, an interactive and graphical development environment that made it possible to explore ideas very quickly and made it fun to discover programming. A recently posted live coding tutorial shows the same basic idea applied to interactive 3D. In the video, an animated strand of DNA is constructed step by step simply by typing a simple script and looking at the result in real-time."

+ - Create 3D animated slideshows in minutes->

Submitted by
descubes
descubes writes "With animated backgrounds, 3D objects, YouTube videos and true stereoscopic 3D, all controlled by a dynamic scripting language, Tao Presentations is not your average presentation software. The latest release includes new easy to use themes to make it easy to create amazing animated slideshows in minutes."

+ - French entrepreneurs use pigeons against "Startup Killer" finance law->

Submitted by
descubes
descubes writes "There’s been a recent flurry of activity on twitter around the #geonpi hashtag. What is going on?

The short version is that French entrepreneurs are all up in arms against the French budget law for 2013. On the surface, one aspect of the law is intended to align the taxation of capital on the taxation of other revenues. But the reasons that entrepreneurs react is that, in practice, the new taxation may well make the creation of startups in France completely untenable."

+ - Converting RSS feeds to a dynamic 3D scene in 120 lines of code-> 4

Submitted by
descubes
descubes writes "Tao Presentations is a 3D presentation tool based on a 3D dynamic document description language. This makes it very easy for developers to create their own 3D shows, illustrate talks in an innovative way, even build small interactive 3D applications. An example included in the latest release grabs RSS feeds from a variety of sources (including Slashdot) and turns them into a 3D scene, all in real-time and in about 120 lines of code. It fetches the pictures directly from the web site and maps them on 3D shapes. And this is only a starting point. Tao Presentations can display 3D objects, drive the majority of 3D displays (including glasses-free 3D displays from Alioscopy, Philips or Tridelity), use GLSL shaders for advanced effects, and much more.

Tao Presentations is free (as in beer), and the document description language is based on the free (as in speech) XL programming language. If you get bored of Powerpoint and are looking for a more stimulating alternative, Tao Presentations may be what you were looking for."

+ - Google News, Slashdot and Twitter in 3D->

Submitted by descubes
descubes writes "Looking for a cooler way to create twitter walls or read Slashdot? The latest demo of Taodyne's Tao Presentations renders RSS feeds from Google News, Twitter or Slashdot as a 3D scene in real-time. All it takes is about 120 lines of simple code to break down the data using regular expressions, and then create a dynamic scene containing texts, pictures, animations..."

+ - Do you prefer your app blinking or upside down? (video)->

Submitted by
descubes
descubes writes "It looked like a simple bug: an OpenGL application that blinks in full screen. But the rest of the day was an infuriating tale of Kill All Humans installers and Beware of The Leopard DRM restrictions. And at the end of the day, an unanswered question remains. What kind of driver bug could possibly cause an OpenGL application to blink in full screen, unless the display is rotated?"

+ - Control avatars and 3D worlds with Kinect->

Submitted by descubes
descubes writes "The Kinect is more than just for games. SimplySim, a French startup making it easy to build 3D simulations and applications, has just posted a video showing how you can interact with photorealistic simulations just by moving the body. Is the Minority Report user interface finally becoming a reality?"

+ - Stereoscopy: What works, what doesn't->

Submitted by descubes
descubes writes "We have been looking for a relatively cheap way to present the output of a 3D application using stereoscopy. Our objective was to see how an OpenGL application could generate stereoscopic output using commercially-available low-cost hardware. Our expectation was that a budget 3D laptop and a budget 3D projector would make for a budget 3D presentation solution. We tried machines with ATI and Nvidia chipsets, internal and external displays, Windows, Linux and MacOSX. The solution that ended up working the best was a total surprise..."

+ - The early days of 3D games->

Submitted by
Christophe de Dinechin
Christophe de Dinechin writes "What was Infogrames like when they occupied a single floor of a single building? Was Frederick Raynal already such a bright guy long before becoming insanely famous for "Alone in the Dark" (answer: yes)? How do you draw 3D using mostly additions? As the author of one of the earliest 3D videogames, I wrote a personal account of these crazy days, back when real men coded on real CPUs which had no clue about real numbers (aka floating point)."
