Abstract The simulation of subtractive manufacturing processes has a long history in engineering. Corresponding predictions are utilized for planning, validation and optimization, e.g., CNC-machining processes. With the up-rise flexible robotic machining advancements computational algorithmic capability, coupled machine-process behaviour complex large workpieces is within reach. These simulatio...
The increasing availability of SPECT/CT devices with advanced technology offers the opportunity for the accurate assessment of the radiation dose to the biological target volume during radionuclide therapy. Voxel dosimetry can be performed employing direct Monte Carlo radiation transport simulations, based on both morphological and functional images of the patient. On the other hand, for voxel ...
We present a novel extension to shape grammars, in which the generated shapes are voxelized. This allows easy Boolean geometry operations on the shapes, and detailing of generated models at a sub-shape level, both of which are extremely difficult to do in conventional shape grammar implementations. We outline a four step algorithm for using these extensions, discuss a number of optional enhance...
Image-based reconstruction from randomly scattered views is a challenging problem. We present a new algorithm that extends Seitz and Dyer’s Voxel Coloring algorithm. Unlike their algorithm, ours can use images from arbitrary camera locations. The key problem in this class of algorithms is that of identifying the images from which a voxel is visible. Unlike Kutulakos and Seitz’s Space Carving te...
