WebCubes [9]. Marching Cubes takes as input a uniform grid whose vertices are samples of the function and extracts a surface as the zero-contour. For each cube in the grid, Marching Cubes examines the values at the eight cor-ners of the cube and determines the intersection of the sur-face with the edges of the cube. Then Marching Cubes pro- WebMarching Cubes 33) in which the 15 original con gurations are increased to 33.
