normals

Estimates normals for surface meshes.

Installation

Using npm:

npm install normals

Example

Here is how to compute the vertex and face normals for the Stanford bunny:

    var bunny = require("bunny");
    bunny.vertexNormals = require("normals").vertexNormals(bunny.cells, bunny.positions[,epsilon]);
    bunny.faceNormals = require("normals").faceNormals(bunny.cells, bunny.positions[,epsilon]);

require("normals").vertexNormals(cells, positions[,epsilon])

This estimates the vertex normals for an oriented mesh.

  • cells is an array of indexed vertex positions
  • positions is an array of vertex positions

Returns: An array of length = positions.length of the per-vertex normals.

require("normals").faceNormals(cells, positions[,epsilon])

This estimates the face normals for an oriented mesh.

  • cells is an array of indexed vertex positions
  • positions is an array of vertex positions

Returns: An array of length = cells.length of the per-face normals.
