signed-distance

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")(grid, 0.1), 
              require("normals").faceNormals(mesh.positions, mesh.faces),
              [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
