Voxelize Mesh
With Voxelize Mesh, a voxel structure is generated based on the currently loaded meshes. Voxelize Mesh provides the same functionality as ImportGeo-CAD, the only significant difference is that ImportGeo-CAD works on the meshes during their import, while Voxelize Mesh works on the meshes which are already in memory.
Voxelize Mesh is only available in MeshGeo, since it works on the mesh currently loaded in GeoDict. With ExportGeo-CAD, the meshes are saved directly and not loaded in the GeoDict user interface.
When a surface triangulation is loaded, select Voxelize Mesh and click Edit… to open the Voxelize Mesh dialog. When all settings have been chosen, click Voxelize at the bottom of the MeshGeo section to create the mesh.
Some of the settings in the Voxelize Mesh dialog are analogous to the ImportGeo-CAD dialog. The more detailed explanation of the settings can be found in the ImportGeo-CAD handbook.
Keep Current Structure
If Keep Current Structure is chosen, the currently loaded structure is not removed and the new structure voxelized from the mesh will be added to the current structure.

Voxelize Mode
|
There are three voxelize modes: Voxelize all at once, Voxelize per Object, and Voxelize per Component.
Voxelize per Object voxelizes the mesh using object indices saved in the mesh, and Voxelize per Component creates the voxel geometry per connected component saved in the mesh. The different objects or components are converted to different Material IDs. The two options are also useful to handle overlapping objects. Voxelize all at once converts all loaded meshes to one material ID in the voxel geometry.

Create Index Image
The option Create Index Image is only available for Voxelize per Object and Voxelize per Component. It creates an index image containing the object ID for Voxelize per Object or component ID for Voxelize per Component.

Material ID selection
The table lists on the first column the currently loaded meshes and on the second column the Material ID that can be assigned to the corresponding meshes after voxelizing.
|
Define Default Overlap
With this option, the user can assign specific materials to overlap regions. If no default overlap is defined, the material ID of the overlap regions is automatically computed through a binary addition of the IDs of the overlap materials.
