Creation of Placement b3dm (Textured Building) #3

Hello Bertt,

i use your Project pg2b3m to create LoD2 Buildings and it works very well. In number 5 of your Example you add Textures to the models. As far as i can tell they are included in the b3dm-Tiles. Can you explain the process behind it?

Hi, this was the result of a custom project. In this project we visualized on the map dynamically created IFC models from buildings.

Workflow was as follows:

store IFC models + location + heading/pitch/roll values;
convert IFC models to glTF models;
convert glTF models to 3D Tiles (tileset.json + b3dm tiles);
Visualize on MapBox GL JS.

The b3dm's are just a container for glTF files, you can use a tool like https://github.com/bertt/b3dm.tooling with unpack option to get the glTF's.

Thanks, works very well for a single Building. There are a few problems for multiple Buildings, but i think i can solve it.

yes luckily in our case the ifc/glTF models per building were not very big (after glTF compression) so we decide to put each building in a b3dm tile. Otherwise an extra step is needed for cutting the building in multiple pieces.
