The code shows a simple example of integration of threejs and draco javascript decoder. From the example, you should be able to loading an encoded draco mesh file and visualize it through threejs's fancy 3D tools. How to run the example code: (1) Create your working directory, e.g. draco_example/. (2) Download the latest three.js file from: https://github.com/mrdoob/three.js/blob/dev/build/three.js You could clone the repository and copy three.js from build/ to your working directory. (3) Copy DRACOLoader.js and webgl_loader_draco.html from draco/javascript/example to your working directory. Copy draco_decoder.js from draco/javascript to your working directory. (4) From your working directory, start a local http server. E.g, with Python, you could run "python -m SimpleHTTPServer". (5) Load webgl_loader_draco.html. You should be able to see an empty scene rendered by threejs. (6) Click "Choose File" to select a draco encoded file (.drc) and you should be able to see the model. e.g. bunny.drc. This is model encoded using Draco default compression. The original ply is located here "testdata/bun_zipper.ply".
