Domains toolbox

Not Lite, Not UAV

The tools in the Domain toolbox are used to define domains, to assign domain information for triangles, and to display domains.

Domains are related to the triangles in TerraModeler surface models. The domain number is stored for each triangle in the surface model TIN file.

You can use domains to separate different types of surface regions from each other. By defining a list of domains, you can create your own classification system for surface regions. This classification system may be used for visualization purposes. It allows to distinguish different-looking surfaces regions from each other.

Typically, you create a list of domains for various regions of the ground surface. The list could include domains such as ground, grass, rock, forest, or road. For each domain a unique coloring scheme and level should be assigned.

Display Domain Triangles tool draws surface model triangles using coloring schemes and levels that are assigned for each domain. If each domain is drawn on a unique CAD file level, it is easier to do further manipulation with CAD tools, such as:

•Apply area pattern on all triangles belonging to a certain domain using the Bentley Pattern Area tool.

•Assign Bentley CAD rendering materials to triangles belonging to a certain domain.

•Drape an aerial photograph on a surface model using material assignment.

There are also a few tools in TerraModeler which enable the application of processes to certain domains only. Examples are Display Contours, Display Themes, Draw Profile, Compute Area.
