Support to open 3DS files

[GoogleCodeExporter]

Could we have 3DS file opening support?

3DS loading support is not in plan at this moment. If you would like to write 
one, the JSC3D.BinaryStream class will be very useful to deal with binary data. 
You can also refer to JSC3D.StlLoader or this demo 
http://jsc3d.googlecode.com/svn/trunk/jsc3d/demos/md2viewer.html which 
implements an experimental MD2 loader as technical tutorials for how to load 
and parse binary data and make models run in JSC3D.

Today I started to implement a 3ds loader.

Now in the end of the day I can see the full mesh rendered but without any 
materials from 3ds file. (the material is the default material of the jsc3d 
engine)

In the next days I'll implement the materials reader from 3ds file and then 
maybe the project owner will integrate it officially in the release.

;)

I tested an object with more than 2 millions of triangles. (and the loader did 
not crash)

If someone is interested to test it (or maybe to contribute) i atteched the 
latest version of the loader.

All you have to do is to include the script into the page after the jsc3d.js.

For example like that:

    <script type="text/javascript" src="../jsc3d.js"></script>
    <script type="text/javascript" src="../jsc3d_Autodesk3DSLoader.js"></script>

and then....

viewer.setParameter('SceneUrl', 'Autodesk3ds/epilator.3ds');

exactly like any other loader.

Hi,

in the attached zip I put the latest version of 3ds loader and my customized 
version of jsc3D.

what you'll find inside the zip:
1. Now the 3DS loader supports also materials ambient + diffuse + texture 
2. This version does not support material opacity (don't know if the 3DS format 
itself supports opacity didn't find such    information in the documentation I 
used)
3. The jsc3d version included into this zip supports transparent background for 
canvas. (As you can see the colored circles are visible from behind the canvas.)
4. Also use a Perspective View (JSC3D by is implemented with Orthographic View) 
and for my project I preferred to use a perspective view.


Enjoy !

Nice job!! I didn't check the issue for email notification so that I almost 
missed this.

The new loader is just incredible. Thanks Vasile!
