I have a triangular mesh that has 1038458 polygons, 517817 points, 1557687 edges. During the simplification process, I am getting the message that there are 1092 disconnected vertices, 516725 connected vertices. Because of disconnected components, the simplification is not improving as expected Using VTK how can I check which vertices are disconnected and color them so I can visualize them clearly and can dig into them.
Any suggestions will be helpful.
I have attached the mesh file here.
