Most traffic accidents are caused by human factors. The design of the driver environment has proven essential to facilitate safe driving. With the advent of new devices such as mobile telephones, GPS-navigation and similar systems the workload on the driver has been even more complicated. There is an obvious need for tools supporting objective evaluation of such systems, in order to design more effective and simpler driver environments. At the moment video is the most used technique for capturing the drivers visual behaviour. But the analysis of these recordings is very time consuming and only give an estimate of where the visual attention is. An automated tool for analysing visual behaviour would minimize the post processing drastically and leave more time for understanding the data. In this thesis the development of a tool for visualising where the driver’s attention is while driving the vehicle. This includes methods for playing back data stored on a hard drive, but also methods for joining data from multiple different sources.

The main purpose of this paper is to provide a detailed analysis of some of the major available open source rendering libraries with the emphasis on their notable characteristics, and an in-depth comparison among them with regards to their possible practical use. Specifically, the selected rendering libraries in this paper are the following - OpenSceneGraph, Ogre 3D, Irrlicht Engine, Crystal Space and OpenSG, but a sidenote is given to some of the others as well. Last but not least, self-made examples of their usage are also included, and are meant to demonstrate some of the mentioned characteristics and principles of the analysed libraries.

This thesis deals with design, implementation and analysis of the model for dynamic changes in the terrain. Present state of terrain deformation in OpenSceneGraph environment is described and available relevant software called TDS, which allows terrain adaptation to new inserted objects is presented. Special emphasis is placed on design of model for physically based terrain deformations that are caused by moving object or by bomb explosion. The results of simulation tests are presented and on the base of model analysis, the optimizations, which significantly improve final algorithm, are designed and realized.

This master's thesis deals with physical simulation of cars. Program is implemented in C++ using OpenSceneGraph and Bullet libraries, which are shortly introduced. The application is implemented as simple racing game for one or two players. Using a simple menu, the user can select a car and the weather, which dramatically affects the handling characteristics of vehicles. Setting weather to random is one of the options leading to a dynamic weather changes during the game. The application takes into account collisions among cars and collisions with the terrain and bars on a racing circuit.

This paper deals with studying skeletal animation techniques, and the subsequent design and implementation of skeletal animation extension for the GPUEngine library. The theoretical part describes the techniques of animation, skeletal animation and skinning. The following is an analysis of existing skeletal animation systems. The proposed solution seeks to reduce the data redundancy in the memory while rendering more skeletal models. According to the design a basic skeletal animation system has been implemented. Furthermore, a demonstration application has been created showing the skeletal system's use. The resulting skeletal system can be used in simple 3D applications and can serve as a basis for further works.

Present graphic requires a lot of optimizations of rendering techniques and mathematical calculations. It is caused by increased requirements of scene's visualization. One of scene's optimizing techniques is the Level of detail. This thesis is focused on methods used by LOD in OpenSceneGraph and OpenGL library. Next it will be described how to choose the right level of detail in a scene. Later it will be explained how to simplify 3D models. These techniques will be implemented in converting tool and demonstrating application. Methods for simplify 3D models will be tested for their speed and quality.

This work describes important periods of making application on editing 3D scene. It concerns a program which makes possible visualization of objects and simulation graphic scene. The introduction of this document is dedicated to theorical analysis, which is oriented on objects presentation in computer graphic with detailed orientation on Boundary Representation. The following chapter is about transformations and manipulators. Design part introduces basic problems and apprises with exercise solutions on general level. In the part of the implementation, we find detailed description of actual solution for particular phase of proposal. It states description of advanced camera system and transformation of objects by the help of graphic manipulators. The next chapter discuss implement effects, modifications and solution for graphical user interface.
