Real time simulation and visualization of NC milling processes for inhomogeneous materials on low-end graphics hardware

Simulation and visualization of NC milling processes has become an important step in computer aided manufacturing. The usage of stock materials with specific locally varying properties (like density, accuracy, color...) becomes more and more important with new technologies emerging in the material industry. Our approach, using volumetric representation, has been adapted to this needs and copes with inhomogeneous material properties. Taking color as one possible material properly, our approach enables the visualization of milled milled wood al compound materials. Furthermore, our approach has been developed with the usage of low-end graphics hardware in mind. The algorithms have been optimized to ensure interactive update rates evert on standard personal computers without hardware graphics acceleration.
