The Linux Gamers' HOWTO The Linux Gamers' HOWTO Peter Jay Salzman Frédéric Delanoy Copyright © 2001, 2002 Peter Jay Salzman Copyright © 2003, 2004 Peter Jay Salzman, Frédéric Delanoy 2004−11−13 v.1.0.6 Abstract The same questions get asked repeatedly on Linux related mailing lists and news groups. Many of them arise because people don't know as much as they should about how things "work" on Linux, at least, as far as games go. Gaming can be a tough pursuit; it requires knowledge from an incredibly vast range of topics from compilers to libraries to system administration to networking to XFree86 administration ... you get the picture. Every aspect of your computer plays a role in gaming. It's a demanding topic, but this fact is shadowed by the primary goal of gaming: to have fun and blow off some steam. This document is a stepping stone to get the most common problems resolved and to give people the knowledge to begin thinking intelligently about what is going on with their games. Just as with anything else on Linux, you need to know a little more about what's going on behind the scenes with your system to be able to keep your games healthy or to diagnose and fix them when they're not. <p(at)dirac(dot)org> / http://www.dirac.org/p.

Wielowątkowość jest postrzegana jako trudne zadanie do wdrożenia i nie jest w pełni rozwinięta. Programiści często unikają jej, ponieważ do prawidłowego wdrożenia wymaga wiele pracy. Według mnie wynikający z tego wzrost wydajności jest warty tych kosztów. Ponieważ nie ma wielu silników gier, które w pełni wykorzystują wielowątkowość, celem tej pracy jest zaprojektowanie i zaproponowanie wielowątkowej architektury silnika gry 3D, a także przedstawienie głównych systemów używanych do stworzenia takiego silnika gry 3D. Praca skupia się na technologii i architekturze silnika gry i jego podsystemach wraz ze strukturami danych i algorytmami wykorzystywanymi do ich stworzenia.

  • Game Audio Via Openal
    Game Audio via OpenAL Summary In the Graphics For Games module, you learnt how to use OpenGL to create complex graphical scenes, improving your programming skills along the way, and learning about data structures such as scene graphs. In this workshop, you'll see how to add sounds to your game worlds using the OpenAL sound library. New Concepts Sound in games, OpenAL, PCM audio, binary file formats, FourCC codes, WAV files, limited resource management Introduction Audio has played an important part in gaming almost as long as there have been games to play - even Pong back in 1972 had simple sound effects. We've moved a long way from then; the 80s brought dedicated audio hardware such as the Commodore 64's SID chip that could play 3 simultaneous syn- thesised sounds, and later the Amiga brought the ability to play audio samples to the home gaming market. In modern gaming hardware, we can expect to hear many simultaneous sounds and music tracks, often in surround sound. Game developers now employ dedicated sound engineers that will carefully adjust the sounds in each game release to create an immersive aural experience - making sure that each individual sound is uniquely identifiable and correctly equalised, and that every music track suits the situation they will be played in. At the heart of a game's audio experience is the code that plays back the game sounds, and cal- culates which speakers they should use - the sound system. Although we can't hope to compete with the complex sound systems of AAA games, we should still be able to make a robust, simple system for the addition of sound in our 3D games, and that's what this workshop will assist you in creating.

  • Release Notes for Xfree86® 4.8.0 the Xfree86 Project, Inc December 2008
    Release Notes for XFree86® 4.8.0 The XFree86 Project, Inc December 2008 Abstract This document contains information about the various features and their current sta- tus in the XFree86 4.8.0 release. 1. Introduction to the 4.x Release Series XFree86 4.0 was the first official release of the XFree86 4 series. The current release (4.8.0) is the latest in that series. The XFree86 4.x series represents a significant redesign of the XFree86 X server,with a strong focus on modularity and configurability. 2. Configuration: aQuickSynopsis Automatic configuration was introduced with XFree86 4.4.0 which makes it possible to start XFree86 without first creating a configuration file. This has been further improved in subsequent releases. If you experienced any problems with automatic configuration in a previous release, it is worth trying it again with this release. While the initial automatic configuration support was originally targeted just for Linux and the FreeBSD variants, as of 4.5.0 it also includes Solaris, NetBSD and OpenBSD support. Full support for automatic configuration is planned for other platforms in futurereleases. If you arerunning Linux, FreeBSD, NetBSD, OpenBSD, or Solaris, try Auto Configuration by run- ning: XFree86 -autoconfig If you want to customise some things afterwards, you can cut and paste the automatically gener- ated configuration from the /var/log/XFree86.0.log file into an XF86Config file and make your customisations there. If you need to customise some parts of the configuration while leav- ing others to be automatically detected, you can combine a partial static configuration with the automatically detected one by running: XFree86 -appendauto If you areusing a platform that is not currently supported, then you must try one of the older methods for getting started like "xf86cfg", which is our graphical configuration tool.
