Shadows calculated for a Shadow Overlay.

The Shadow Overlay stores the result of a Shade calculation caused by the sun. The sun's altitude and azimuth are stored as model attribute in the Shadow Overlay.

The sun's altitude and azimuth can be automatically configured using the Shadow Overlay Wizard. Users can specify multiple dates and specific hours for each. These dates, in combination with the project's world location are used to obtain the altitude and azimuth of the sun. Each individual date corresponds to a separate timeframe of the Shadow Overlay.

The shadow calculation takes into account both the Terrain Elevation and the Building Elevation. Additionally, the Foliage Height can be specified, or calculated automatically using a Foliage crown factor.

Notes

  • Shadow overlay is identical to the Shade result type of an Heat Stress Overlay. However, using this specific Overlay is approximately 10 times faster then calculating the Shade with the overhead of the complete DPRA Heat Stress Module.
