Signed distance field computations for meshes

Usage & Install

Via npm:

npm install signed-distance

Here is how you can use it:

    var mesh = require("bunny");
    var dist = require("signed-distance")(
                  require("spatial-grid")(mesh.cells, mesh.positions, 0.1), 
                  require("normals").faceNormals(mesh.cells, mesh.positions),
                  [1.0, 0.0, 0.0]);

require("signed-distance")(grid, faceNormals, point)

Computes the signed distance to the mesh from point

  • grid: A spatial grid
  • faceNormals: The normals of the mesh
  • point: The point to query

Returns: The signed distance to the boundary of the mesh, or else NaN
