DUAL CONTOURING WORK METHOD FOR CYLINDRICAL PARTPROBLEM TO BE SOLVED: To improve productivity while protecting a cutting tool, and work not only an outer diameter of a cylindrical part but also an inner diameter in a dual contouring work method.MIZUNO YOSHIAKI...
While a dual contouring mesh is always water tight, it’s not always a well defined surface. As there’s only one point per cell, if two surfaces pass through a cell, they will share it. This is called a “non-manifold” mesh, and it can mess with some texturing algorithms. This is...
This paper provides several contributions related to dual contouring implicit data including solving rank deficient QEF's, reducing memory requirements, and performing fast polygon updates during CSG. First, we describe our method for solving QEF's and provide a method using mass points that improves...
摘要: This paper describes a new method for contouring a signed grid whose edges are tagged by Hermite data (i.e; exact intersection points and normals). This method avoids the need to explicitly identif...关键词: contouring crack prevention implicit functions polyhedral simplification quadratic ...

The code can take in two kinds of input: .dcf (Dual Contouring Format) and .sog (Signed Octree with Geometry). Both formats store an octree grid with inside/outside signs. DCF contains intersection points and normals on grid edges, whereas SOG contains a single point location within each ...
