Abstract
A decoding method is a decoding method of decoding three-dimensional points, and includes: calculating a position of a first point on an edge connecting two Triangle-Soup (TriSoup) vertices of a first TriSoup triangle using the two TriSoup vertices; shifting the position of the first point in a first direction; and generating a second TriSoup triangle using the first point having the position shifted, in which the first TriSoup triangle is used to generate a plurality of three-dimensional points in a node according to a TriSoup scheme, and the node is a unit in an octree structure including the plurality of three-dimensional points.
Claims12
A decoding method of decoding three-dimensional points, the decoding method comprising:
- calculating a position of a first point on an edge connecting two Triangle-Soup (TriSoup) vertices of a first TriSoup triangle using the two TriSoup vertices;
