Understanding the Virtual Lighting Controller Parameters

The following page presents the different parameters to correctly use the Virtual Lighting Controller.



Select all / Unselect all

These parameters allows you to select or unselect all the layers of the current configuration.

Update / Automatic Update

Update allows you to compute manually the modifications you made through the Virtual Lighting Controller. The modification applies only when clicking Update.

Automatic update allows you to compute the data in real time. Modifications are applied automatically when performing the change.

Layer Configuration

You can add or remove unlimited configurations. Each configuration is independent from each other.

Data modifications are only applied into the current selected configuration.

Power Value / Ratio Value

The default displayed ratio value is 100%.

Layer Deletion

Note: The Layer Deletion is only available in the Virtual Lighting Controller of Virtual Photometric Lab, Virtual Human Vision Lab and 3D Energy Density Lab.

The Layer Deletion allows you to delete a layer.

  • The layer is deleted for all created layer configurations.
  • Deleting layer is irreversible.
  • You cannot delete a layer if there is only one existing layer.

Specific Vision Parameters

Note: Specific Vision Parameters is only available in the Virtual Lighting Controller of Virtual Human Vision Lab.

Specific Vision Parameters allows you to apply vision parameters on a specific layer configuration. The others configurations will not inherit the vision parameters applied for this layer configuration.

To apply specific vision parameters, follow the procedure Applying Specific Vision Parameters to a Layer Configuration.

Spectral Map

In case you loaded a spectral map, the Virtual Lighting Controller allows you to display the spectrum of each light source.

  • This tool allows you to display the spectral information of the source, and possibly modify the spectrum of the source.

To modify the spectrum of a source, follow the procedure Defining a New Light Source Spectrum.

  • This icon warns you that no spectral data is saved in the XMP spectral map.
  • This icon informs you that a new spectrum has been added to the source.
  • This icon allows you to get back to the initial source.
