triangulates a series of 2D contours
npm install triangulate-contours
Triangulates a series of contours using Tess2.js. Returns a simplicial complex with { positions, cells }. Works with 2D and 3D coordinates, and contours can be in reverse winding order for holes.
``js
var triangulate = require('triangulate-contours')
var contours = [
[ [10,50], [55, 23], [15, 62], [23, 63], [63, 21], [11, -2] ],
[ [50,50], [62,21], [24,52] ]
]
var results = triangulate(contours)
console.log(results)
/*
{ positions: [ ... ], cells: [ ... ] }
*/
`
positions are a series of points with the same number of components as the input, and cells is a list of faces with indices into the positions array.
#### triangulate(contours[, opts])
Triangulates an array of polylines, each polyline representing a contour. The options will be pushed into Tess2 constructor; but if no vertexSize is specified, it will be guessed based on the input array (i.e. 2-dimensional vs. 3-dimensional vectors).
Returns a simplicial complex, i.e. a simple object:
`js``
{
positions: [ [x,y], .. ],
cells: [ [a,b,c], .. ]
}
