Deformable Volumetric Simplex Meshes

چکیده
In this article, two possible ways to build volumetric meshes of simplexes are described. One structure uses the crystalline organization of carbon atoms in diamond and it is used to simulate the deformation under internal pressure of a container. The second structure is in layers and it is used to simulate human body tissues that could be cut. We also describe the cutting process for this layered structure.

متن کاملSurface Simplex Meshes for 3D Medical Image Segmentation
Medical image segmentation is often a diicult task due to the low contrast, the low signal/noise ratio and the presence of outliers in images. However, it remains a critical issue for image interpretation, pattern recognition and automatic diagnosis. Deformable models are well-suited for capturing the geometry and the shape variability of anatomical structures from medical images. Indeed, they ...
