Book Description
This dissertation provides the theoretical basis and implementation details for a complete and practical real-time voxel-based terrain rendering system. We first present a modified Marching Cubes algorithm designed to eliminate choices arising from ambiguities in the original algorithm and its successors in order to facilitate a faster implementation and to simplify the design of a level-of-detail algorithm. The modified Marching Cubes algorithm is extended to operate on voxel data at multiple resolutions in such a way that triangle meshes produced at all levels of detail correctly match geometrical features. We introduce a robust method for seamlessly joining voxel-based terrain meshes of different levels of detail and establish a transition structure that both simplifies the triangulation problem and eliminates the potential for shading artifacts. Finally, we discuss methods for applying texture maps and advanced shading techniques to voxel-based terrain meshes. These methods are designed to be fast and compatible with the widest possible range of graphics hardware across multiple platforms.

Book Description
Photo-realistic terrain generation in real-time is critical to the success of many real-time graphics and virtual reality applications, such as flight simulators. This thesis presents algorithms to generate virtual terrain and render the terrain in real time in graphics processors. The terrain geometry is generated by the Fractional Brownian Motion algorithm with the initial shape controlled by user input. Instead of using expensive satellite image, the ground layer texture is synthesized by a model cover layer, added onto it are several small textures that can be tiled seamlessly. The model cover layer provides a 3D model of the terrain with a general distribution function to include realistic conditions to the terrain with multiple instances of ground features scattered in. The thesis also discusses the algorithm to use programmable GPU to create real-time shadow and blend the ground layer texture in the shader program.

Book Description
Virtual Manufacturing presents a novel concept of combining human computer interfaces with virtual reality for discrete and continuous manufacturing systems. The authors address the relevant concepts of manufacturing engineering, virtual reality, and computer science and engineering, before embarking on a description of the methodology for building augmented reality for manufacturing processes and manufacturing systems. Virtual Manufacturing is centered on the description of the development of augmented reality models for a range of processes based on CNC, PLC, SCADA, mechatronics and on embedded systems. Further discussions address the use of augmented reality for developing augmented reality models to control contemporary manufacturing systems and to acquire micro- and macro-level decision parameters for managers to boost profitability of their manufacturing systems. Guiding readers through the building of their own virtual factory software, Virtual Manufacturing comes with access to online files and software that will enable readers to create a virtual factory, operate it and experiment with it. This is a valuable source of information with a useful toolkit for anyone interested in virtual manufacturing, including advanced undergraduate students, postgraduate students and researchers.
