APPENDIX EThree-Dimensional Modeling Using Point Clouds and TINs in Oracle

Due to the recent advances in laser-scanning technologies, the acquisition of location and height information using laser scanners and other such equipment has become quite popular. Many companies utilize such laser-scanning techniques to create three-dimensional point datasets (the first two dimensions, x,y, for location, and the third dimension, z, for height) in a variety of applications including city modeling, bathymetry (ocean floor modeling), and three-dimensional object modeling. Since such point datasets are usually dense, they are referred to as point clouds. Figure E-1 shows the typical workflow for creating three-dimensional representations of objects using ...
