I have a .shp file with buildings represented as polygons.

Top view

3D

My goal is that, in a 3D representation, I am able to have different colors in a single polygon (building) depending on its height. For example, from 0 to 10 meters, buildings are yellow, then from 10 to 20 m they are blue, and so on.
Is there any way of doing this in QGIS or using PyQGIS? I have tried to add copies of the buildings to the shapefile with different heights and the number of copies depends on the height of the building, and then pick a different color for each building copy, but it does not work, still only one color appears.

EDIT: This is an exemplification of what I'm looking for: Example

EDIT2: Using the Properties > 3D View > Rule-based, and then View > New 3D Map View, I get a 2D map :( : new 3d map view

You can achieve this by setting rule based 3d rendering. Navigate to Properties > 3D View > Rule-based and create your own rules and styling.

I did this really quick crude example:

  • How do you visualize the 3D map? – rocker996 Jan 6 at 16:31
  • In QGIS go to View > New 3D Map View – AWGIS Jan 6 at 16:40
  • Doesn't work for me, it still shows in 2D – rocker996 Jan 6 at 17:17
  • What version of QGIS are you using and can you show a screenshot of the 3D view – AWGIS Jan 7 at 9:05
