WebMar 17, 2014 · One of the most used representation in the filed computer graphics and geometry processing is the halfedge data structure. Polygonal meshes consist of geometry (vertices) and topology (edges, faces). Data structure for polygonal meshes mainly differ in the way they store the topology information. http://462cmu.github.io/asst2_meshedit/

WebJan 5, 2007 · A half-edge path is a sequence of half-edges (h_1, …, h_n), such that destination (h_i) = origin (h_ {i + 1}), for all i in [1, n]. The half-edge path is a loop, if destination (h_n) = origin (h_1). The half-edge loop is properly oriented, if polygon (h_i) = polygon (1), for all i in [1, n]. A half-edge is reserved, if polygon (h) exists. WebA typescript implementation of the Halfedge structure for three.js geometries.
