Domain Generator

The Domain Generator allows you to create a surface mesh (domain) that approximates the surface of a 3D object. This domain enables the visualization of illumination data, helping to analyze the interaction between the laser and the object’s geometry.

Generate a Domain

Follow these steps to generate a domain:

Open the Domain Generator Panel

Open the Domain Generator panel in the LIATool addon. If no object is selected, the panel will indicate “none object selected…”.

Opening the Domain Generator panel with no object selected.

Select an Object

Use the dropdown menu to select the object for which you want to generate the domain. Select the desired object from the list (e.g., “Cube”).

Selecting an object to generate the domain.

Adjust Domain Resolution

Configure the background mesh fineness by selecting a resolution from the dropdown menu. Options include Very Coarse, Coarse, Moderate, Fine, and Very Fine. A higher resolution provides a more detailed domain but may take longer to compute.

Adjusting the resolution of the background mesh.

Generate the Domain

Once the object and resolution are selected, click the Generate Background Mesh button to create the domain. The generated domain will appear as a surface mesh over the selected object.

Edit or Remove a Domain

Domains can be adjusted or removed as needed:

• Edit the Domain Change the resolution or regenerate the domain by reconfiguring the settings and clicking Generate Background Mesh again.

• Remove the Domain To delete the domain, use Blender’s standard object deletion method. Select the domain object and press the Delete or X key to remove it from the scene.
