Code Review of Doom For the iPhone 161

Posted by Soulskill from the old-dogs-new-tricks dept.
Developer Fabien Sanglard has written a code review for id Software's iPhone port of Doom. It's an interesting look into how the original 1993 game (which he also reviewed to understand its rendering process) was adapted to a modern platform. "Just like Wolfenstein 3D, Doom was rendering a screenframe pixel per pixel. The only way to do this on iPhone with an acceptable framerate would be to use CoreSurface/CoreSurface.h framework. But it is unfortunately restricted and using it would prevent distribution on the AppStore. The only solution is to use OpenGL, but this comes with a few challenges: Doom was faking 3D with a 2D map. OpenGL needs real 3D vertices. More than 3D vertices, OpenGL needs data to be sent as triangles (among other things because they are easy to rasterize). But Doom sectors were made of arbitrary forms. Doom 1993's perspective was also faked, it was actually closer to an orthogonal projection than a perspective projection. Doom was using VGA palette indexing to perform special effect (red for damage, silver for invulnerable...)."

NASA To Cryogenically Freeze Satellite Mirrors 47

Posted by Soulskill from the ain't-it-cool dept.
coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

3D Blu-ray Spec Finalized, PS3 Supported 157

Posted by Soulskill from the but-at-least-one-dimension-will-have-drm dept.
Lucas123 writes "The Blu-ray Disc Association announced today that it has finalized the specification for Blu-ray 3-D discs. The market for 3-D, which includes 3-D enabled televisions, is expected to be $15.8 billion by 2015. Blu-ray 3-D will create a full 1080p resolution image for both eyes using MPEG4-MVC format. Even though two hi-def images are produced, the overhead is typically only 50% compared to equivalent 2D content. The spec also allows PS3 game consoles to play Blu-ray 3-D content. 'The specification also incorporates enhanced graphic features for 3D. These features provide a new experience for users, enabling navigation using 3D graphic menus and displaying 3D subtitles positioned in 3D video.'"

Íslensk Erfðagreining wich is the company that handles everything concerning the data and the research can not by law hand over the data to a second company. Decode is the parent company of Íslensk Erfðagreining. A little bit of research would have gotten you the knowledge that they can only use the private and medical information that they have gotten in research purposes and can never hand it over. This article just smells like fud to me.

Submission + - DNA testing firm goes bankrupt, who gets the data?

Submitted by wiedzmin
wiedzmin writes: DeCODE Genetics, a genetics research firm from Iceland has filed for bankruptcy in the U.S. and Saga Investments, a U.S. venture capital firm, has already put in a bid to buy deCODE’s operations, raising privacy concerns about the fate of customer DNA samples and records. The company hasn’t disclosed how many clients signed up for its service, but provides a number of customer testimonials on its site, including Dorrit Mousaieff, Iceland’s first lady.
