Urban Visualization Platform
On this platform an overview of different visualizations for a variety of (3D) data is provided.
The examples shown here were mainly created during the iCity research projects at HFT Stuttgart (University of Applied Sciences Stuttgart).
Wind in Stuttgart, Kernerviertel
![](imgs/thumbnails/Kirchturm_keine_Partikel.jpg)
Visualisation of wind around three target buildings (red) near a church with spire and surrounded by numerous building layers (colors). The streamlines results from a Computational Fluid Dynamic simulation of the air flow with RANS (Reynold-Averaged Navier Stokes Equations) and the k-omega SST Turbulence model.

Pressure PointCloud (3D Tiles)
![](imgs/thumbnails/PointCloud.jpg)
Wind pressure around a building block visualzied as a point cloud. Color represents different pressure values according to legend.
Streamlines with particles
![](imgs/thumbnails/StreamlinesMultipart_particles.jpg)
Multipart streamlines with vertex coloring showing also particles moving along the streamslines in order to give a better impression of the wind field.
Multi-Color/Part Streamlines
![](imgs/thumbnails/StreamlinesMultipart.jpg)
Wind speed around a building block visualzied using Cesium multicolor multi-part lines primitives. Color represents different wind speeds, values according to legend.
Hexgrid GeoJSON (5m)
![](imgs/thumbnails/HexGrid5m_PressureMeanGeoJSON.jpg)
Wind pressure at roof top height, Hexgrid (hexagon width 5m) is clamped to ground and buildings.
Streamlines (3D Tiles)
![](imgs/thumbnails/StreamLinesCesiumOverview.jpg)
Streamlines showing wind flow over and around a building block and parts of Stoeckach. Wind speed is encoded as color information as of the legend.
Hexgrid 3D Tiles (2m)
![](imgs/thumbnails/HexGrid2m_PressureMean3DTiles.jpg)
Wind pressure at roof top height, shown as a floating 3D Tiles Hexgrid (hexagon width 2m).
Hexgrid 3D Tiles (15m)
![](imgs/thumbnails/HexGrid15m.jpg)
Wind pressure at roof top height, shown as a floating 3D Tiles hexgrid (hexagon width 15m).
WindowDetection on Buildings
![](imgs/thumbnails/EssenPC.jpg)
Showing results from automatic window detection from LiDaR point clouds. Results are shown on top of 3D building models and the original point cloud.
