node-stl-to-thumbnail

Create thumbnail from 3D STL file. Creates beautifully rendered png and jpeg output server-side with no GPU from ASCII and Binary STL's.

This code is forked from node-stl-to-thumbnail by instructables but I cannot found it in Github anymore.

Installation

npm install --save node-stl-to-thumbnail

Usage

The following snippet loads a file from the current directory (./input.stl), and creates a 500x500 png thumbnail in the current directory called ./output.png.

var StlThumbnailer = require('node-stl-to-thumbnail');
var fs = require('fs');
 
var thumbnailer = new StlThumbnailer({
    filePath: __dirname + "/input.stl",
    requestThumbnails: [
        {
            width: 500,
            height: 500
        }
    ] 	
})
.then(function(thumbnails){
    // thumbnails is an array (in matching order to your requests) of Canvas objects
    // you can write them to disk, return them to web users, etc
    // see node-canvas documentation at https://github.com/Automattic/node-canvas
    thumbnails[0].toBuffer(function(err, buf){      
        fs.writeFileSync(__dirname + "/output.png", buf);
    })
})

Help needed

To be honest, I am not fully understand this. Need help on:

1. Camera setting, so that can get view from any perspective I want
2. Render setting so that it look beautiful. If you see Three.js website the 3D item are so beautiful
3. Update to use latest JavaScript ( ES2015++ )
