quadratic error mesh decimation.
simplified interface for mesh-simplifier - use simple triangles instead of Three.js geometry.
similar to mesh-simplify but based on mesh-simplifier because it is much faster.
all are based on or influenced by this code by sp4cerat.
``sh`
npm i simplify-triangles
`javascript
var fs = require("fs");
var stl = require("stl");
var st = require('simplify-triangles');
//each triangle has format [ [x,y,z], [x,y,z], [x,y,z] ]
//load triangles from stl file
var triangles = stl.toObject(fs.readFileSync('./skull.stl')).facets.map(f=>f.verts);
//simplify the triangle mesh, result will have 0.125x as many triangles
//format is same as input
var simplifiedTriangles = st.simplify(triangles,0.125);
//optional - view the result with ascii-raytracer
var config = {
triangles: simplifiedTriangles,
cameraPos: [45.82,22.11,61.08],
cameraRot: [1.87,-2.25],
aspectRatio: 4/3,
screenShotDir: "/Users/user/Desktop/"
}
require('ascii-raytracer').runScene(config);
