Mesh Measurements

The algorithm performs curve length measurements on the surface defined by the mesh. The curves on the surface can be specified by the user interactively inside the 3D views.

Input

A single mesh.

Output

A table of measurements that can be exported into a text file.

Description

In the 3D view a user can select two points on the mesh surface by double clicking on the mesh. Depending on the mode (Geodesic distance ticked or unticked), two different distance measurements are taken.

• Geodesic distance: The algorithm computes the shortest curve on the mesh that connects the two specified points and computes its length.
• Non-geodesic distance: The algorithm cuts the mesh with a plane, which goes through the selected points. The resulting cutting curve is determined together with its length.

After a measurement is taken, it can be modified (only for non-geodesic mode) by selecting Advanced mode and adjusting the plane by translating or rotating it. Or it can be added to the table by clicking Append measurement to the table. The measurement table allows to rename (by double clicking the cell in the Name column) or delete a measurement. When the distance is geodesic, a user can also decide to close the measurement contour by checking the Closed checkbox.

This process can be iterated for several measurements. The measurements can be exported as annotations to the annotation widget by clicking on Export to annotation model, stored via Save measurements or loaded by Load measurements.
