  • Programmation Amigaos
    Découverte de la Programmation AmigaOS Version 1.0 - 07/11/2003 http://www.guru-meditation.net Avant-propos Bonjour à tous, A l’occasion de l’Alchimie, nous sommes très heureux de faire voir le jour à ce document en français sur la programmation Amiga. Il devrait représenter une précieuse source d’informations et il sera complété et corrigé au fil du temps. Le but de ce livret est de vous offrir des clés, des pistes pour partir sur les chemins du développement en les balisant. Par exemple, vous ne trouverez pas ici de tutoriels sur l’utilisation des bibliothèques ou des devices du système. Nous donnons ici des principes et des conseils mais pas de code : pour des sources et des exemples, nous vous renvoyons à notre site (http://www.guru-meditation.net) et un chapitre est en plus réservé à la recherche d’informations. Nous essaierons de prendre en compte un maximum de configurations possible, de signaler par exemple les spécificités de MorphOS, ... Quelque soit le système, on peut d’ors et déjà déconseiller à tous de “coder comme à la belle époque” comme on entend parfois, c’est à dire en outrepassant le système. Nous souhaitons, par le développement, contribuer à un avenir plus serein de l’Amiga. C’est pourquoi, parfois avec un pincement, nous omettrons de parler d’outils ou de pratiques “révolus”. On conseillera avant tout ceux qui sont maintenus et modernes ... ou encore, à défaut, anciens mais indispensables. Objectif : futur. Ce livret est très porté vers le langage C mais donne malgré tout de nombreux éclairages sur la programmation en général.

People with 3D Hardware should select MiniGL/Warp3D. It looks nicer and performs better. The game is also playable in Software-Rendering, though. You also can select between Fullscreen and Window Mode on this Tab. Audio On this tab you can choose between AHI and Paula-Sound. Also you can setup your CD Drive for CD Audio Replay (or disable it). Input On this Tab you can Enable or Disable the Mouse and the Joystick. As to the Joystick, the following Input-Devices are supported: - CD 32 Pad - PSX Port - PC-Analog-Stick, by using a Custom-Made Adapter and wessupport.library (included on CD). The same adaptor which worked for Descent:Freespace and ADescent also works for Quake 2. For PSX Port and PC-Joysticks you can also manipulate the Joystick-Speed and the Deadzone. In case you use a PC-Joystick, PSX Port and CD32 Pad will be disabled. In case you use PSX Port you can choose to disable all other Joysticks, if wanted. Game This is the Tab which comes up, when you start up the GUI. Here you can chooce between Deathmatch, Cooperative Gaming and CTF (as supported by Mods).

  • Step-Through Debugging of GLSL Shaders
    Step-Through Debugging of GLSL Shaders Hilgart, Mark School of Computer Science, DePaul University, Chicago, USA Abstract Programmers writing in the OpenGL Shading Language (GLSL) today rely on printf-style debugging methods and IDEs that set up test environments. However, as shaders get more complex, traditional step-through debugging on shaders running in their intended application becomes more useful. This paper describes a rewriting method that enables step-through debugging on GLSL shaders that are running in the user’s program. Full- screen debugging is used first to identify interesting pixels, then individual pixels are stepped through to completely understand their behavior. This rewriting method can be made transparent to the user, and serves as an alternative to planned library support. I. Introduction SGI brought hardware 3D acceleration to the scientific and visualization communities in 1983. Their first machine was the Iris 1000 and sold for tens of thousands of dollars. To allow program- mers to use the hardware, SGI provided a library called IrisGL. This library would allow the CPU to send scene data and textures to the 3D hardware as well as control how it rendered the scene. This is also how OpenGL works, which was based on IrisGL. SGI to this day still only produces non-programmable 3D hardware, meaning the way the scene is rendered with their hardware can only be managed in a limited number of ways. Most notably the lighting model is fixed, and all materials tend to look similar. This also means non-3D uses are extremely limited. The year 1983 also saw the world’s first shader language written by Ken Perlin[16].

A variety of device drivers allows Mesa to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs. Mesa ties into several other open-source projects: the Direct Rendering Infrastructure and X.org to provide OpenGL support to users of X on Linux, FreeBSD and other operating systems. Project History The Mesa project was originally started by Brian Paul.

  • Opensg: a Scene Graph System for Flexible and Efficient Realtime
    OpenSG: A Scene Graph System for Flexible and Efficient Realtime Rendering for Virtual and Augmented Reality Applications Vom Fachbereich Informatik der Technischen Universität Darmstadt genehmigte DISSERTATION zur Erlangung des akademischen Grades eines Doktor-Ingenieur (Dr.-Ing.) von Dipl.-Inform. Dirk Reiners aus Bergisch Gladbach Referenten der Arbeit: Prof. Dr. José L. Encarnação Prof. Dr. Stefan Müller Tag der Einreichung: 5. Mai 2002 Tag der mündlichen Prüfung: 21. Juni 2002 D17 Darmstädter Dissertationen 2002 Acknowledgements This work wouldn’t have been possible without the continuous support and encour- agement from a number of people. I would like to thank Prof. Dr. José L. Encarnação for creating and maintaining an en- vironment that encourages experimentation and free research without letting people drift too far off track, but keeping them focussed on what needs to be done. My department head Stefan Müller was always there for me and kept believing in me even when I didn’t. Which can be very annoying, but sometimes is just what’s necessary. Many ideas were formed and formalized in intensive discussions with the rest of the OpenSG dream team, Gerrit Voss and Johannes Behr, without whom many mistakes would have been made and many good aproaches ignored. Many ideas were fine-tuned in discussion with other members of the graphics and later OpenSG community. Allen Bierbaum and David Blythe were instrumental in getting everything started. All my colleagues from the A4 department were helpful in making even the hard times fun and enjoyable. Their influence on the overall work environment and general motivation can not be overestimated.
