3D Polymesh

A 3D polymesh is a collection of vertices, edges and faces that defines the shape of a polygonal object. The faces consist of triangles (triangle mesh), quadrilaterals (quad mesh), or other simple convex polygons (n-gons). The faces are rendered as a polymesh and saved as a .DXF file type. Import the DXF file into Surfer and a base(vector) layer is created in the plot window with the 3D polymesh as a component. Click on the Map object and then click the Map Tools | View | 3D View command to view the polymesh in the 3D view window.

To Import and View a 3D Polymesh:

  1. Use the File | Open command.
  2. Select a DXF file in the Open dialog and click Open.
  3. Specify options in the DXF Import Options dialog and click OK. The map is automatically created with reasonable defaults.
  4. Click on the Map object in the Contents window.
  5. Click the Map Tools | View | 3D View command.

3D Polymesh Tips

  • Polymeshes must be imported into Surfer.
  • To change the features of the polymesh, click once on the base(vector) layer in the plot window or on the polymesh in the Contents window to select it.
  • Single-color meshes will be rendered as solid-color faces but if each face has a different color then the faces will render as separate colors.
  • Meshes with colors per vertex render as colored wireframe polymeshes.
  • Textured meshes render as black wireframes.
  • Click on the Map object in the Contents window. On the View page in the Properties window, check that the Tilt is 90°. Angles other than 90° may distort the polymesh in the 3D view window.

Polymesh Layer Properties

A polymesh cannot be edited in Surfer. Only the Info page is included in the polymesh properties.
