shared-edge-angle

calculate the angle between two triangles in 3d with a shared edge

example

var findAngle = require('shared-edge-angle')
var A = [[0,0,0],[0,1,0],[1,0,0]]
var B = [[0,0,0],[0,1,0],[0,1,1]]
console.log(findAngle(A,B)*180/Math.PI)

output:

90

api

var findAngle = require('shared-edge-angle')

var angle = findAngle(A, B)

Calculate the angle between triangles A and B in radians.

A and B are presumed to have a shared edge.

Each triangle in A and B should be 3-element array of 3-element [x,y,z] triangle coordinates.
