Watertight and 2-Manifold Surface Meshes Using Dual Contouring With Tetrahedral Decomposition of Grid Cubes
The Dual Contouring algorithm (DC) is a grid-based process used to generate surface meshes from volumetric data. The advantage of DC is that it can reproduce sharp features by inserting vertices anywhere inside the grid cube, as opposed to the Marching Cubes (MC) algorithm that can insert vertices only on the grid edges. However, DC is unable to guarantee 2-manifold and watertight meshes due to...
متن کاملMulti-resolution Dual Contouring from Volumetric Data
We present a Multi-Resolution Dual method based on an incremental octree-based refinement strategy. Our solution is able to generate multi-resolution surfaces from segmented volumetric data. It extends the Dual Marching Cubes algorithm over a generalized octree and guarantees that the produced surfaces are always manifold by introducing a new cell-based criterion for dual vertices generation. M...
متن کاملDual Contouring for Domains with Topology Ambiguity
This paper describes an automatic and robust approach to generate quality triangular meshes for complicated domains with topology ambiguity. In previous works, we developed an octree-based Dual Contouring (DC) method to construct triangular meshes for complicated domains. However, topology ambiguity exists and causes non-conformal meshes. In this study, we discuss all possible topology configur...
متن کاملContouring by electronic speckle pattern interferometry employing dual beam illumination.
In this paper we extend and study the method for generating contours of diffuse objects employing a dual beam illumination coupled with electronic speckle pattern interferometry. The sensitivity and the orientation of the contour planes are analyzed. A novel method for tilting the planes of contours and experimental results incorporating phase shifting and fringe analysis are also presented. Th...
متن کاملDual Marching Tetrahedra: Contouring in the Tetrahedronal Environment
We discuss the dual marching tetrahedra (DMT) method. The DMT can be viewed as a generalization of the classical cuberille method of Chen et al. to a tetrahedronal. The cuberille method produces a rendering of quadrilaterals comprising a surface that separates voxels deemed to be contained in an object of interest from those voxels not in the object. A cuberille is a region of 3D space partitio...
