Adaptive Extended Marching Cubes
The demands related to Volumetric Models are increasing rapidly due to the availability of 3D scanner, but its application in the manipulation of volumetric data raises several issues that need to be addressed. The fundamental of manipulating volumetric data includes isosurface extraction, while sharp features of 3D models are well preserved with Extended Marching Cubes algorithm (EMC). However...
متن کاملOn Marching Cubes
A characterization and classification of the isosurfaces of trilinear functions is presented. Based upon these results, a new algorithm for computing a triangular mesh approximation to isosurfaces for data given on a 3D rectilinear grid is presented. The original marching cubes algorithm is based upon linear interpolation along edges of the voxels. The asymptotic decider method is based upon bi...
متن کامل(No) More Marching Cubes
Isosurfaces, one of the most fundamental volumetric visualization tools, are commonly rendered using the wellknown Marching Cubes cases that approximate contours of trilinearly-interpolated scalar fields. While a complete set of cases has recently been published by Nielson, the formal proof that these cases are the only ones possible and that they are topologically correct is difficult to follo...
متن کاملProbabilistic Marching Cubes
In this paper we revisit the computation and visualization of equivalents to isocontours in uncertain scalar fields. We model uncertainty by discrete random fields and, in contrast to previous methods, also take arbitrary spatial correlations into account. Starting with joint distributions of the random variables associated to the sample locations, we compute level crossing probabilities for ce...
متن کاملMarching cubes: surface complexity measure
In this work we give an approach to analyse a surface topology complexity inside a cube in the Marching Cube (MC) algorithm. The number of the isosurface intersections with the cube diagonals is used as the complexity criterion. In the case of the trilinear interpolation we have the cubic equation on the each cube diagonal and there is a possibility to find the coordinates of the three intersec...
