Create a Surface Triangulation for the resulting structure by creating a Surface Mesh. This feature is only available if you have leased or purchased a MeshGeo license.

The structure is segmented into two phases and the isosurface wraps around the high gray value values which are assigned to Material ID 01 with normal pointing into the pore space which is assigned to Material ID 00.

Segment the gray value image either with an Automatic Threshold or with a manual threshold entered for Threshold.

If Automatic Threshold is enabled, the Otsu method is used to threshold the image.

When Add to current mesh is selected and a mesh is already in memory, the new mesh is added to that mesh. Multiple meshes can then be edited together and saved to a single file.

If Coarsen during creation is checked, the number of triangles in the generated surface mesh is reduced.

Three different Modes to Coarsen triangulations are provided, based on the stopping criteria for the coarsening algorithm:

• by Percentage Reduction of Triangles
• by Edge Length
• by Target Number of Triangles

The coarsening algorithm reduces the number of triangles in the generated mesh by combining short edges to longer edges.

For a detailed description and examples for the triangulation parameters see the MeshGeo user guide.

Click Surface Triangulation to start the process. After the triangulation is finished, the resulting mesh is displayed in the GUI visualization area.
