| Abstract | The purpose of this work is to define a new algorithm for converting a CSG representation into a B-Rep representation. Usually this conversion is done determining the union, intersection or difference from two B-Rep represented solids. We will define another approach where the space used by the solids is determined as a volumetric representation. Then, using the volumetric representation a B-Rep Solid Model is created. Such an algorithm can be used in the future for creating B-Rep Solid Models from Three Dimensional Medical Images. Generating a full Solid Model instead of the traditional approach of only Surface Representations for 3D medical images, has the advantage that mass properties are easily extracted from a Solid Model, such as: volume, moment of inertia and mass centre. The surface representation does not guarantee that a closed volume is created. It is enough for visualization. However, for engineering purposes as analysis or stereolitography manufacturing, a closed volume is necessary. A solid model is a complete representation for engineering purposes. The construction of a Solid Model is different from the traditional construction of a surface model; thus we modified the marching cubes algorithm to reach this objective. |
