Visualize Delaunay mesh with MeshLab

To visualize a Delaunay mesh using MeshLab, you’d typically be visualizing the 3D Delaunay triangulation (or tetrahedrization) of a set of points. Here’s how you can do that:

1. Input Data:
   • Ensure you have a set of 3D points in a format that MeshLab can read (e.g., .ply, .xyz, .obj, etc.).
   • If your Delaunay mesh is already constructed and saved in a format like .off or .ply, you can skip directly to step 4.
2. Load Points into MeshLab:
   • Open MeshLab.
   • Go to File -> Import Mesh (or drag and drop) to load your set of 3D points.
3. Generate Delaunay Triangulation:
   • After loading the points, go to Filters -> Point Set -> Delaunay Triangulation.
   • This will generate the Delaunay triangulation of your 3D point set.
4. Visualize the Mesh:
   • Once the Delaunay triangulation is generated (or if you’ve loaded an existing Delaunay mesh), you should see the mesh in the main visualization area.
   • You can manipulate the view using the mouse:
     • Left-click & drag to rotate.
     • Right-click & drag to pan.
     • Scroll wheel to zoom.
5. Change Visualization Style (Optional):
   • If you want to see both the points and the mesh, you can change the rendering style.
   • In the right panel, under Render, you can toggle on/off various visualization options, such as points, wireframe, and solid rendering.
6. Save the Mesh (If you generated it in MeshLab):
   • Go to File -> Export Mesh As and choose your desired format.

That’s it! You should now be able to visualize the Delaunay mesh in MeshLab. Remember that MeshLab offers a lot of features, so you can further process, refine, and visualize your mesh using various filters and tools.
