3D Object Task

Add Your 3D Buildings

In this lecture, you will learn how to add 3D objects — such as untextured or textured buildings — to your map project using the VC Publisher.

Adding 3D objects is a key step in building your Digital Twin, representing the built environment in three dimensions.

Depending on your data, the buildings can be:

  • Untextured models – simple 3D geometry, ideal for structural analysis or spatial calculations.

  • Textured models – detailed buildings with facade and roof textures, bringing your model closer to a realistic appearance.

This process supports both analytical use cases (such as energy or shadow analysis) and visually engaging presentations.

What You Will Learn

  • How to configure the 3D Object Task in the VC Publisher

  • How to prepare and convert untextured building models

  • How to prepare and convert textured building models

  • How to preview your 3D objects and check alignment

Steps Overview

  1. Open the VC Publisher and go to the home section of your project.

  2. Select the "New 3D Object Task".

  3. Add a name and description for your layer.

  4. Reference your 3D object files in CityGML or CityJSON formats using default settings, and check the applied zoom levels, LoD information, and texture settings.

  5. Preview the objects to verify correct placement and appearance.

  6. Later, add these objects into your map using the App Configurator.


Check that your 3D models use the correct coordinate system and are properly aligned with your terrain and other layers.

Textured buildings require texture image files (e.g., JPEG, PNG) to be stored in the correct folder structure referenced by the 3D model.
