In previous works, we developed an octree-based Dual Contouring (DC) method to construct surface and volumetric meshes for complicated domains. However, topology ambiguity exists and causes non-conformal meshes. In this study, we discuss all possible topology configurations and develop an extension ...
notes. Two algorithms are implemented in this code: the original dual contouring algorithm [Ju et al., Siggraph 2002] and the intersection-free extension [Ju et al., Pacific Graphics 2006]. You can switch between them in the main() function in dc.cpp. In addition, octree simplification (...

Another dual contouring annoyance is it can sometimes generate a 3d surface that intersects itself. For most uses, this is completely ignorable, so I have not addressed it. There is a paper discussing how to deal with it:“Intersection-free Contouring on An Octree Grid” Ju and Udeshi 2006 ...

An Octree cell with eight child nodesThe Octree seems to be the favoured data structure in all of the literature, because it allows you to easily reason about which cells neighbour which others at varying resolutions, and for the kinds of meshes usually being considered it produces an adequate...

This new method imposes no constraints on the octree (such as being a restricted octree) and requires no "crack patching". We conclude with a simple test for preserving the topology of the contour during simplification. 展开 关键词: implicit functions contouring crack prevention quadratic error ...
