==What is the GEOMETRY_COLOR attribute?==
The GEOMETRY_COLOR [[Attribute]] allows for updating the color of [[functions]], specified by Attribute, by using the [[Tygron Query Language]]. It actually does not overwrite the color, so removing the attribute will restore the original color of the model.
The GEOMETRY_COLOR attribute enables the option to update the color of [[functions]], specified by attribute, by using a [[TQL|Tygron Query Language (TQL)]] query. It actually does not overwrite the color, so removing the attribute will restore the original color of the model.


==How to use the GEOMETRY_COLOR attribute==
==Specific Use Cases==
As the operation is performed by TQL, the task can be done in the [[Editor]], with the [[Query Tool]]. More advanced users can also perform these queries through the [[API]].
*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 [[Custom Geometry|3D models]] that lack textures ([[I3S]]/ 3D BAG/ [[CityGML]])
**Construct a query that gives a corresponding color to each Function type.

Icon Attribute Unit Range Description
GEOMETRY_COLOR Color Updates building color to custom color selection.

The GEOMETRY_COLOR Attribute allows for updating the color of functions, specified by Attribute, by using the Tygron Query Language. 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.
