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). -

Hexgrid 3D Tiles (15m)
+
Wind in Stuttgart, Kernerviertel
- +
-

Wind pressure at roof top height, shown as a floating 3D Tiles hexgrid (hexagon width 15m).

+

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.
