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...".

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").

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.

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.
