Reference Manual

This package implements several grid-based isosurfacing algorithms (Marching Cubes, its topologically correct variant, and Dual Contouring) that enable generating surface meshes from 3D value and gradient fields. The methods are generic with respect to the definition of the grid and the fields, and all methods offer parallel implementations. The output is a polygon soup (i.e., a container of 3D point coordinates and indexed faces).
