Abstract
In applications for technical problems, Geometric modeling and sensor technology are key in both scientific and industrial development. Simulations and visualization techniques are the next step after defining geometry models and data types. This thesis attempts to combine different aspects of geometric modeling and sensor technology as well as to facilitate simulation and visualization. It includes two areas; - Applications and tools for geometric modeling, such as constructions, physical problems, terrain generation and cutting algorithms. - Sensor technology and a generic layer of information as a result of measurements and data analysis in connection with visualization, modeling, development of hybrid solutions and methods for assessing road conditions. Visualization and data presentation is important when dealing with applications and tools for studying properties, such methods for visualization and constructions are presented.
