Details

This example is very similar to implicit_curve_2d.cpp; however, instead of extracting a curve from a triangulation of a surface, this time we extract a surface from a quad tessellation of a hexahedron. In addition to what we demonstrate with implicit_curve_2d.cpp, this example also demonstrates:

• How to use an SDF to identify cells that contain the level set
• How to export only a subset of cells
