Geometry Caching

Before the X3D Propagation Model runs a simulation, it must first load and process all active geometry features. Wireless InSite automatically manages cached processed geometry for reuse on subsequent and concurrent X3D runs, eliminating the need to repeat the processing step. When Wireless InSite determines that a project's geometry has not changed, the cached geometry will be reused for future X3D simulations.

This provides dramatic time savings when running many studies with the same geometry, especially when the geometry contains many facets. This is also helpful when returning to a project that was run at an earlier time. For example, a project including urban geometry, foliage, and terrain elevation data can be run initially to generate the cache files. Subsequent simulations run within that geometry will be able to simply load geometry from the cache file. Figure 1 shows Barcelona urban, foliage and terrain geometry with multiple small cell study area boundaries, where independent simulations can be run using the same processed geometry. In this case geometry processing time is reduced from several minutes to a few seconds.
