2.5D Terrain Triangulation and Point Cloud Simplification

2.5D Delaunay triangulations (TIN – Triangulated Irregular Networks) are like a 2D Delaunay triangulation, but with elevated points. This article describes the optional simplification of point clouds from LiDAR scans and surface metrology data using adaptive and grid-based clustering methods. Further it shows how to triangulate point clouds in a memory-efficient way and how to…
