Greedy triangulation algorithm
WebThe algorithm does not require the polygon to be simple, thus it can be applied to polygons with holes. Generally, this algorithm can triangulate a planar subdivision with n vertices in O(n log n) time using O(n) space. Dual graph of a triangulation. A useful graph that is often associated with a triangulation of a polygon P is the dual graph. Web2.2. Greedy Projection Triangulation Greedy projection triangulation bridges computer vision and computer graphics. It converts the scattered point cloud into an optimized spatial triangle mesh, thereby reflecting the topological Figure 1. Point cloud registration chart. FPFH (fast point feature histograms). 2.1.
