Or try out the following live demo:

First, install the library via npm:
npm install isosurface
Extracts an isosurface from potential
using surface nets with resolution given by dims
.
Params:
dims
: A 3D vector of integers representing the resolution of the isosurfacepotential(x,y,z)
: A scalar valued potential function taking 3 coordinates as arguments returning a scalar.bounds
: A pair of 3D vectors[lo, hi]
giving bounds on the potential to sample. If not specified, default is[[0,0,0], dims]
.
Returns: A mesh object with the following members:
positions
: The coordinates of the vertices of the meshcells
: The faces of the mesh.
Same as above, except uses marching cubes instead of surface nets to extract the isosurface.
Same as above, except uses marching tetrahedra instead of surface nets to extract the isosurface.
