mesh-laplacian

Computes the Laplacian of a mesh.

Install

npm i mesh-laplacian

Example

var bunny   = require('bunny')
var lapList = require('mesh-laplacian')(bunny.cells, bunny.positions)
var lapMat  = require('csr-matrix').fromList(lapList)

API

var mat = require('mesh-laplacian')(cells, positions)

Constructs the mesh Laplacian for a given surface mesh using barycentric cotangent weights.

• cells are the faces of the mesh
• positions are the coordinates of the vertices of the mesh

Returns A list of entries of the form [vi,vj,w] representing the entries of the Laplaican matrix for the mesh.
