Example

    <script src="/javascripts/Three.js"></script>
    <script src="/javascripts/plane.js"></script>
    <script src="/javascripts/thingiview.js"></script>

    <script>
      window.onload = function() {
        thingiurlbase = "/javascripts";
        thingiview = new Thingiview("viewer");
        thingiview.setObjectColor('#C0D8F0');
        thingiview.initScene();
        thingiview.loadSTL("/objects/cube.stl");
      }
    </script>

    <div id="viewer" style="width:300px;height:300px"></div>

Usage

It's important that everything is done within window.onload.

thingiurlbase = "/javascripts";

Must be set to the path where the javascript files are located so that related scripts can be loaded dynamically.

thingiview = new Thingiview("id of viewer's container div");

Pass the id of the div to place the viewer into. You can set the width and height on the css for that div.

thingiview.initScene();

Loads the scene into the container div.

thingiview.loadSTL("/path/to/model.stl"); or thingiview.loadOBJ("/path/to/model.obj");

Make sure you pass the full url path to the model file you want to load. This will make an ajax call to the server to fetch it.

thingiview.setShowPlane(true);

true or false. Show or hide the 100x100 grid plane under the object.

thingiview.setBackgroundColor('#ffffff');

Sets the background color of the viewer's container.

thingiview.setObjectMaterial('solid');

solid or wireframe. Changes the object's material.

thingiview.setObjectColor('#C0D8F0');

Yep, it sets the object's color.

thingiview.setRotation(true);

true or false. This causes the object to slowly rotate around the z axis.

thingiview.setCameraView('top');

Possible values include: top, side, bottom, diagonal. Resets the camera view to the desired angle.

thingiview.setCameraZoom(5);

Pass a positive number to zoom the camera in or a negative number to zoom out.

thingiview.displayAlert("This is a message");

Displays the text passed in a window inside the viewer with an Ok button to then hide it.
