triangle-quadrature v1.0.0

triangle-quadrature

Gaussian quadrature for a triangle.

Usage

var bunny      = require('bunny')
var quadrature = require('triangle-quadrature')([bunny.positions[0], bunny.positions[1], bunny.positions[2])
console.log(quadrature) # <- {positions: [...], weights: [...]}

require("triangle-quadrature")(positions, [order = 5])

Computes Gaussian quadrature for a triangle defined by positions (three vec3s). Optionally, you can set a custom order, higher implying greater accuracy. To actually integrate using these quadrature points, simply take a sum of your integrand at positions weighted by weights.
