General Discussion / How to release a demo with the FREE version
« on: November 25, 2009, 11:34:50 AM »
You can create with the FREE version of GeeXLab a demo that is lauchable directly with a double-click on an executable file.
But the end-user will always have access to demo’s source codes (xml, glsl and lua files). Only the commercial version (PRO) of GeeXLab makes it possible to protect the source codes of the demo.

Once the demo coded and operational, just create a folder where you will copy your demo files (xml, lua, glsl and media). Then copy in that folder GeeXLab.exe executable with its DLL and plugins (*.o3p). All plugins are not mandatory: if the demo, for instance, does not use particles, it's not necessary to copy particle system plugins (particle_system_plugins folder). Now that the demo’s folder is ok, you need to do the following tasks:
  • edit config.gxml file and change auto_load attribute of startup node. auto_load holds the name of the demo file: in our case it’s the main XML file, the one that contains the root node geexlab.
  • set to 0 check_version attribute. That will disable online check for new versions of GeeXLab (currently the online check is always disabled but maybe it will be enabled in the future).
  • rename GeeXLab.exe: for example with myKool3DDemo.exe
  • archive all the demo in a nice zip file and put it in download somewhere in the Net.

The end user has only to unzip the demo and double-click on myKool3DDemo.exe to launch the demo.

You can also pack all data in a zip file and specify the zip filename in the archive_filename attrib of the scene node. But some medias can not be loaded from a zip like 3DS models.

Today, in 24 hours of non-stop running, Dual-GPU GeForce GTX 295's are capable of running a protein folding simulation at 1400 nanoseconds, or 1.4 milliseconds. That means that unfortunately, we need 714 GTX295's to simulate a single second of protein folding. If you want to simulate 24 hours, you need 61,689,600 GeForce GTX 295 graphics cards, i.e.123,379,200 GT200-class graphics processors. Before you ask - yes, that number is higher than the overall number of every manufactured GT200 chip in the world. And that was "just" for Folding@home. At that time,a single CPU core was able to process around 4 [yes, four] nanoseconds,i.e. 150 times slower than the GeForce GTX 280, yet alone newer GPUs.For 24 hours of protein simulation you need 123 million GT200 GPUs or18,506,880,000 Core 2 CPUs. Yes, that's 123 million versus 18 billion.

To take stereographs of dynamic subjects, we will need to take two photos at exactly the same time. Japanese camera manufacturer Fuji recently released the first digital camera equipped with two lenses for 3D. Of course, for the technologically savvy, you can make your own 3D camera rig using common building materials and two digital cameras.

For this project, we’ll use a pair of matching Canon PowerShot cameras and specialized synchronization software called StereoData Maker, or SDM, which is a nonvolatile firmware upgrade based on CHDK, the Canon Hack Development Kit. SDM adds a set of features to certain Canon cameras, specifically for the taking of 3D pictures.

Quote
The “OpenGL Shading Language” (also called the Orange Book because of its orange cover) is back in its meanwhile third edition with updated discussions of the OpenGL shading language up to version 1.40 introduced with OpenGL 3.1. Like the previous edition, the third edition of the book is one of the best introductions to GLSL — the OpenGL Shading Language — that not only teaches the ins and outs of GLSL itself but also explains in-depth how to develop shaders in GLSL for lighting, shadows, animation, and other topics relevant to real-time computer graphics.

General Discussion / Re: Object shadows
« on: November 14, 2009, 01:40:23 PM »
By default, shadow_caster="TRUE" allows to use stencil shadow volumes. No shader is required with shadow volumes.
The only requirement is that your models and meshes must have closed surfaces else you will have visual artifacts
(see at the end of this artticle for details).

Shadow volumes work fine with omni lights but can be CPU intensive if you have dense meshes.

The second technique is the shadow mapping. You have to enable it in the scene node (see the shadow mapping demo).
Shadow mapping works with any mesh or object that modifies the depth buffer. But it suffers from aliasing and then requires the use of shaders to have soft shadows.

Currently GeeXLab supports the basic shadow mapping algorithm so it works fine with spot lights. And depending on your scene, it
can also work with omni light (see HERE).

We don’t typically cover 3D benchmark programs, primarily since they generally have nothing to do with real-world gaming experiences. This new application from Unigine  is a bit different than others though. Unigine is a 3D framework middleware engine that has been used in published games, and will also be used in some upcoming games currently under NDA. The Heaven Benchmark is the first 3D application that is available to us that utilizes DX11 and Tessellation, which will give us a glimpse of what Tessellation could do for us in games.

t's what's inside those trailers, though, that is the key to Microsoft's cloud-computing efforts. Each of the shipping containers in the Chicago data center houses anywhere from 1,800 to 2,500 servers, each of which can be serving up e-mail, managing instant messages, or running applications for Microsoft's soon-to-be-launched cloud-based operating system--Windows Azure.

"I think, I'm not 100 percent sure, but I think this could be the largest data center in the world," said Arne Josefsberg, general manager of infrastructure services for Microsoft's data center operations.

From the second we saw the Sapphire Radeon HD 5870 Vapor-X graphics card we fell in love with it. The card stands out from the crowd and has a bad boy appearance to it that the reference card just doesn't have. The best part about the Sapphire Radeon HD 5870 Vapor-X is that the cooler actually works. We witnessed an 8dBA decrease in fan noise and an insane 18C drop in temperatures while gaming.  The small 2-4% factory overclock gave a slight boost in performance and in every single benchmark we ran the Sapphire Radeon HD 5870 Vapor-X was faster than a stock Radeon HD 5870 video card, albeit by only 1-6FPS depending on the benchmark in question...

AMD has retaken the crown for superior graphical power with their ATI Radeon HD 5870 video card, and consumers have confirmed that this is the hottest graphics accelerator of the moment. Armed with 1600 shader cores, the 40nm Cypress GPU claims to push video game frame rates well-beyond what NVIDIA offers from their GeForce GTX 285 counterpart. While the list of DirectX 11 video games has just started to grow, with one of the first being a free Massive Multiplayer Online Role Playing Game (MMORPG) named BattleForge. Perhaps ATI has created the perfect storm for their Radeon HD 5800-series by offering a price-competitive graphics card with several free games included or available. While NVIDIA toils away with CUDA and PhysX, ATI is busy delivering the next generation of hardware for the gaming community to enjoy. Sapphire factory overclocks the Cypress GPU and adds their own custom cooling solution, named Vapor-X. In this article Benchmark Review! s tests the Sapphire Radeon HD 5870 Vapor-X video card 21161-03 against a cross-section of modern graphics accelerators.
