Problems loading .stl file

[mout99]

Hello, when I try to upload a file. Stl it gives me the following error :

SyntaxError: Unexpected token E in JSON at position 0

 

 

 

      // Get the canvas element from our HTML above
  var canvas = document.getElementById("renderCanvas");

  // Load the BABYLON 3D engine
  var engine = new BABYLON.Engine(canvas, true);

    BABYLON.SceneLoader.Load("js/", "stlfilestl.stl", engine, function (newScene) {
      console.log("reklfjsklf");

      var camera = new BABYLON.ArcRotateCamera("Camera", 0, 0.8, 100, BABYLON.Vector3.Zero(), newScene);

   newScene.activeCamera.attachControl(canvas, false);
   engine.runRenderLoop(function () {
       newScene.render();
    });
      });

is it a binary stl?  we only support ASCII at the moment.

[mout99]

How do I see this? I'm new to this area.

[Pryme8]

Try to open it in notepad, if its human readable then its ASCII if it looks like garbley gook then its binary.

http://www.meshconvert.com/ if it is binary and you don't have the original file to export it as ASCII.

[mout99]

It's already an ASCII, am I right?

[Pryme8]

that's binary, ASCII is readable.

Object start
  Normal ###
     facet start
      vertex ###
      vertex ###
      vertex ###
    facet end
 Object end

or something like that.

I converted to ASCII with the site you recommended to me and is giving the same error, what can it be?

    BABYLON.SceneLoader.ImportMesh("", "js/", "stlfile.stl", scene, function (meshes) {
    });

constructor is wrong, try using the above with the correct file name.

also set up your scene correctly as well, that script that you are using is wrong.

 

var createScene = function () {
    var scene = new BABYLON.Scene(engine);

    //Adding a light
    var light = new BABYLON.PointLight("Omni", new BABYLON.Vector3(20, 20, 100), scene);

    //Adding an Arc Rotate Camera
    var camera = new BABYLON.ArcRotateCamera("Camera", 0, 0.8, 100, BABYLON.Vector3.Zero(), scene);
    camera.attachControl(canvas, false);

    // The first parameter can be used to specify which mesh to import. Here we import all meshes
    BABYLON.SceneLoader.ImportMesh("", "scenes/", "skull.babylon", scene, function (newMeshes) {
        // Set the target of the camera to the first imported mesh
        camera.target = newMeshes[0];
    });

    // Move the light with the camera
    scene.registerBeforeRender(function () {
        light.position = camera.position;
    });

    return scene;
}

is the playground example for loading meshes.

But before you do that you need to review this: http://doc.babylonjs.com/tutorials/creating_a_basic_scene
