This is ninja, our viewer for CityJSON.

The source code is available in GitHub. Have fun and, please, report any issues found here.

Here is what you can do:

• Click on an object ID in the tree view on the left to select it.
• Click or tap on an object in the 3D view to select it.
• When an object is selected you see a card with it's information (oh, wow)! If you click on a surface with semantics, its information will also be accessible.
• Toggle between different LoDs by clicking on the corresponding buttons on the bottom left corner of the viewer.
• Toggle the editing mode with the icon to edit it. Then save the changes.
• Download the city model with your changes by clicking on Download.

You are about to disable performance mode. This might temporarily make your browser unresponsive while the object list is populated. Depending on your model's size, this might take a few seconds. Are you sure you want to disable performance mode?
