convex-minkowski-sum

Computes the Minkowski sum of two convex polytopes encoded as sets of points

Example

var msum = require('convex-minkowski-sum')
 
//A is a triangle in 3D 
var A = [[1,0,0], [0,1,0], [1,1,0]]
 
//B is a line segment 
var B = [[0,-1,0], [0,1,0]]
 
console.log(msum(A,B))

Install

npm install convex-minkowski-sum

API

var msum = require('convex-minkowski-sum')

msum(A,B)

Computes the Minkowski sum of A and B

  • A and B are both arrays of vertices encoded as d-tuples of points

Returns A set of points representing the Minkowski sum of A and B

msum.pairs(A,B)

Computes a set of pairs representing the vertices of the Minkowski sum of A and B

  • A and B are arrays of points

Returns An array of pairs representing the vertices on the convex hull of the Minkowski sum of A and B

msum.faces(A,B)

Computes the faces of the Minkowski sum of A and B

  • A and B are arrays of points

Returns An array of the faces of the Minkowski sum of A and B represented as pairs of lists of vertices in A and B respectively.
