OM-Cube Project
OM-Cube project V. Hiribarren, N. Marchand, N. Talfer [email protected] - [email protected] - [email protected] Abstract. The OM-Cube project is composed of several components like a minimal operating system, a multi- media player, a LCD display and an infra-red controller. They should be chosen to fit the hardware of an em- bedded system. Several other similar projects can provide information on the software that can be chosen. This paper aims to examine the different available tools to build the OM-Multimedia machine. The main purpose is to explore different ways to build an embedded system that fits the hardware and fulfills the project. 1 A Minimal Operating System The operating system is the core of the embedded system, and therefore should be chosen with care. Because of its popu- larity, a Linux based system seems the best choice, but other open systems exist and should be considered. After having elected a system, all unnecessary components may be removed to get a minimal operating system. 1.1 A Linux Operating System Using a Linux kernel has several advantages. As it’s a popular kernel, many drivers and documentation are available. Linux is an open source kernel; therefore it enables anyone to modify its sources and to recompile it. Using Linux in an embedded system requires adapting the kernel to the hardware and to the system needs. A simple method for building a Linux embed- ded system is to create a partition on a development host and to mount it on a temporary mount point. This partition is filled as one goes along and then, the final distribution is put on the target host [Fich02] [LFS]. -

Of Computer and Information Science at Linköpings universitet Abstract The KreaTV Application Development Kit (ADK) product of Motorola en- ables application developers to create high level applications and browser plugins for the IPSTB system. As a result, customers will reduce develop- ment time, cost and supplier dependency. The main goal of this thesis was to port this platform to a standard Linux PC to make it easy to trace the bugs and debug the code. This work has been done by implementing a hardware abstraction layer(HAL)for Linux Operating System. HAL encapsulates the hardware dependent code and HAL APIs provide an abstraction of underlying architecture to the oper- ating system and to application software. So, the embedded platform can be emulated on a standard Linux PC by implementing a HAL for it. We have successfully built the basic building blocks of HAL with some performance degradation. -

Programmable Image-Based Light Capture for Previsualization
ii Abstract Previsualization is a class of techniques for creating approximate previews of a movie sequence in order to visualize a scene prior to shooting it on the set. Often these techniques are used to convey the artistic direction of the story in terms of cinematic elements, such as camera movement, angle, lighting, dialogue, and char- acter motion. Essentially, a movie director uses previsualization (previs) to convey movie visuals as he sees them in his ”minds-eye”. Traditional methods for previs include hand-drawn sketches, Storyboards, scaled models, and photographs, which are created by artists to convey how a scene or character might look or move. A recent trend has been to use 3D graphics applications such as video game engines to perform previs, which is called 3D previs. This type of previs is generally used prior to shooting a scene in order to choreograph camera or character movements. To visualize a scene while being recorded on-set, directors and cinematographers use a technique called On-set previs, which provides a real-time view with little to no processing. Other types of previs, such as Technical previs, emphasize accurately capturing scene properties but lack any interactive manipulation and are usually employed by visual effects crews and not for cinematographers or directors. This dissertation’s focus is on creating a new method for interactive visualization that will automatically capture the on-set lighting and provide interactive manipulation of cinematic elements to facilitate the movie maker’s artistic expression, validate cine- matic choices, and provide guidance to production crews. Our method will overcome the drawbacks of the all previous previs methods by combining photorealistic ren- dering with accurately captured scene details, which is interactively displayed on a mobile capture and rendering platform. -

The Linux Gamers' HOWTO
The Linux Gamers’ HOWTO Peter Jay Salzman Frédéric Delanoy Copyright © 2001, 2002 Peter Jay Salzman Copyright © 2003, 2004 Peter Jay SalzmanFrédéric 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. 1. Administra If you have ideas, corrections or questions relating to this HOWTO, please email me. By receiving feedback on this howto (even if I don’t have the time to answer), you make me feel like I’m doing something useful. In turn, it motivates me to write more and add to this document. -

It is a midweight OS designed to combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint. Relying on the excellent upstream work by Linux and the open-source community, we deploy Xfce 4.12 as Desktop Environment on top of a Debian Stable base, drawing from the core antiX system. Ongoing backports and outside additions to our Repos serve to keep components current with developments. -
A Study on the Use of Opengl in Window Systems

The thesis is equivalent to 20 weeks of full time studies. Contact Information: Author: Johan Persson E-mail: [email protected] University advisor: Bj¨orn T¨ornqvist Department of Software Engineering and Computer Science Department of Software Engineering and Computer Science Internet : http://www.bth.se/ipd Blekinge Institute of Technology Phone : +46 457 38 50 00 Box 520 Fax : + 46 457 271 25 SE - 372 25 Ronneby Sweden Abstract OpenGL is getting used more in window system as a way of improving performance and enabling new functionality. Examples of two systems using different approaches of how OpenGL is being used are Quartz Extreme and Fresco. Quartz Extreme uses window composition which assures fast redisplay and Fresco on the other hand uses a structured graphics approach which utilises OpenGL on a much lower level compared to Quartz Extreme which operates at a window level. Fresco’s way brings great flexibility and an ability to mix 2D and 3D-objects on the desktop. But each of the approaches has its problems; Quartz extreme requires a large amount of memory for buffering of the window contents and Fresco has performance problems when redisplaying complex structures.
