    triangle-normal experimental

    Takes a list of vertices in a triangle, and returns the normal vector for that triangle. Doesn't handle degenerate triangles.

    Installation

    triangle-normal

    Usage

    require('triangle-normal')(vertices..., [output])

    The first 9 arguments are for the points on your triangle, with an optional output array to set the resulting parameters. If an ouput is not supplied, a new array will be created, and either way this array will be returned as the result of the function, e.g.:

    var normal = require('triangle-normal')
    var output = [0, 0, 0]
     
    var vectors = [
        { x: 0, y: 0, z: 0 }
      , { x: 1, y: 0, z: 0 }
      , { x: 0, y: 1, z: 0 }
    ]
     
    normal(
      vectors[0].x, vectors[0].y, vectors[0].z,
      vectors[1].x, vectors[1].y, vectors[1].z,
      vectors[2].x, vectors[2].y, vectors[2].z,
      output
    )
