WWW.ELECTRICALEXPERIMENTER.COM - An archive of The Electrical Expiramenter magazine. ATI. Owners of AMD (previously ATI) video cards have a choice between AMD's proprietary driver (catalyst) and the open source driver (xf86-video-ati).

ATI

This article covers the open source driver. The open source driver is currently not on par with the proprietary driver in terms of 3D performance on newer cards or reliable TV-out support. It does, however, offer better dual-head support, excellent 2D acceleration, and provide sufficient 3D acceleration for OpenGL-accelerated window managers, such as Compiz or KWin. If unsure, try the open source driver first, it will suit most needs and is generally less problematic (see the feature matrix for details). Naming conventions The Radeon brand follows a naming scheme that relates each product to a market segment.

For a table of core and product series, see Wikipedia:Comparison of AMD graphics processing units. Overview The xf86-video-ati (radeon) driver: Works with Radeon chipsets up to HD 6xxx and 7xxxM (latest Northern Islands chipsets). Installation. The Live Workshop. Programming OpenGL On Linux. It seems there are two OpenGL strategies.

Programming OpenGL On Linux

The first is the "Fixed Pipeline". This seems pretty widely supported as it is, I believe, the original way of doing things. All of the original SGI OpenGL examples use this. All hardware before about 2005 supports this (and presumably all OpenGL software written before then uses it). Basically OpenGL versions before 3.0 are oriented towards fixed pipeline (aka immediate mode) and later versions are programmable pipeline. The problem with fixed pipeline OpenGL is, one, it is deprecated and, two, it is much less efficient for many things.

The more modern way of using OpenGL which is not universally supported on all legacy systems is the "Programmable Pipeline". The bigger picture here is that you need to think of your graphics card (or even your integrated graphics chip) as its own separate computer. This special software is written in a special language, GLSL (GL Shader Language). Power Steering: "Hydraulic Steering Principles of Operation" 1955 US Army Auto Mechanics. FIX BSOD ATI Blue screen on atikmdag.sys solved fix. Quote: OMG Jesus you are guru I am a noob this is a fact there is another fact every single people here in this forum say every topic : run driver sweeper and reinstall the drivers 1 - people dont ever need or use third part programs because is not about driver sweeper clean the house for AMD 2- have pass in your mind of guru that this installer of AMD from this guy who do a terrible job in AMD Catalyst and maybe when you instal something go wrong and the file when copied for system 32 maybe because some AV or some other reasons like a bad installer corrupted the file ????

Anyway I do it my job to help the other noobs because I am a noob stop to make guru question for a noob I can say it no doubt this information about to replace the sys file can save a lot of people like me who dont understando nothing. Polyworld: Using Evolution to Design Artificial Intelligence. Evolved Virtual Creatures. This video shows results from a research project involving simulated Darwinian evolutions of virtual block creatures.

Evolved Virtual Creatures

A population of several hundred creatures is created within a supercomputer, and each creature is tested for their ability to perform a given task, such the ability to swim in a simulated water environment. Those that are most successful survive, and their virtual genes containing coded instructions for their growth, are copied, combined, and mutated to make offspring for a new population. The new creatures are again tested, and some may be improvements on their parents. As this cycle of variation and selection continues, creatures with more and more successful behaviors can emerge. The creatures shown are results from many independent simulations in which they were selected for swimming, walking, jumping, following, and competing for control of a green cube.

About MilkDrop

MilkDrop is the next generation of music visualizer. First written in 2001, its popularity seemed to only grow as more and more people explored its possibilities and made increasingly amazing content for it. However, in 2007 I gave it a major update, opening it up to the power of pixel shaders - flexible programs written to run on modern GPUs that can result in spectacular imagery and special effects.

MilkDrop's content is comprised of presets. The MilkDrop 2.25c source code is freely available - you can get it either as a zip, or using git via SourceForge. The original [pre-pixel-shader] MilkDrop (1.x) is also open-sourced -- that source code is here. The 2007 update is called "MilkDrop 2" but is the same program.
