Structure optimization

The command is available in the Processing tab in normal mode and in the editor. It is intended for ordering the structure of the arrangement of mesh edges. To optimize, you need to select the meshes in the tree and select a section on one or more meshes on the scene, set the threshold value of the edge length with the slider and click Optimize. The threshold value of the edge length regulates the detail of the optimized section. This way, you can increase or decrease the step between the meshes. When the edge length decreases, the current triangles are split, and when they increase, they are merged. The algorithm has maximum limits on the threshold for one iteration, since significant changes in the edge length can lead to a lack of RAM.

Optimization can be repeated an unlimited number of times, so the possibility of obtaining the desired edge length, a multiple of 25 microns, is implemented with several iterations of repetitions without the need to exit the widget.

There are several options on the widget that affect the mesh structure. All of them have an impact on the mesh structure and are performed sequentially with the check boxes enabled. It is not recommended to disable all options at the same time, because the algorithm needs at least one command for the action.

When optimizing the structure of meshes with a large number of triangles, the calculation time can be reduced by disabling one or two options and optimizing in stages, first starting splitting the long edges, after combining the short edges and the last step is rebuilding the elongated triangles.

Dihedral angle threshold - the maximum angle for transforming adjacent triangles. If the value of the angle between adjacent triangles in degrees is greater than the specified value, the triangles will not be used in the optimization process.
