The GEOMETRY_COLOR attribute enables the option to update the color of functions, specified by attribute, by using a Tygron Query Language (TQL) query. It actually does not overwrite the color, so removing the attribute will restore the original color of the model.

Specific Use Cases

  • Identify buildings by energy label
    • Give each building an energy label as attribute.
    • Construct a query that gives a corresponding color to each label group.
  • Identify trees with disease/ animal plague
    • Mark each infested tree with a suitable attribute.
    • Construct a query that gives a corresponding color to each label group.
  • Colorize 3D models that lack textures (I3S/ 3D BAG/ CityGML)
    • Construct a query that gives a corresponding color to each Function type.
