3D Simulation is about the analysis of spatial data. While the study of 2D data has been common for many years. Many new kinds of technologies can create 3D data and represent it in 3D. Objects represented in 3D will have coordinates in 3D dimensions and two or more objects can exist in 3D space. We are interested in 3D analysis because it helps us to understand the real dimensions and the location of features in space. This page is about understanding the role of 3D spaces and the relationship of objects and phenomenon between locations or coordinates.
