![]() The gray colored polygon style shown in the map view on the top creates the illusion of shadows in the 3D view:īeyond that, this example also features elevation model data which can be configured in the 3D View panel. All polygons must move in clockwise order which I didn't. In pyshp, this is defined in your parts array using the array 'partTypes'. According to the source of qgs3dutils: AltClampAbsolute, //!< Z_final = z_geometryĪltClampRelative, //!< Z_final = z_terrain + z_geometryĪltClampTerrain, //!< Z_final = z_terrain Multipatch shapefiles need a specialized type for each part which can be: VALUE PART TYPE 0 Triangle Strip 1 Triangle Fan 2 Outer Ring 3 Inner Ring 4 First Ring 5 Ring. Other options are “relative” and “terrain” which add given elevation values to the underlying terrain elevation. Absolute clamping is perfect for the Viennese data since all height values are provided as absolute measures from 0. The altitude clamping setting defines how height values are interpreted. To style the 3D view in QGIS 3, I set height to “U_KOTE” and extrusion to O_KOTE-coalesce(U_KOTE,0)īoth with a default value of 0 which is used if the field or expression is NULL: T_KOTE: lowest point of the terrain for the given building block (“tiefster Punkt des Geländes auf den Kanten der Gebäudeteilfläche”).HOEHE_DGM: absolute height of the terrain (“absolute Geländehöhe”). ![]()
