It seems that the model file is not loaded successfully. What browser are you
using? How about other demos?

Thank you for getting back to me.
This example works fine turtle.html, the obj file examples do not.
turtle.html works in Firefox 22 and IE 10, bmw.html does not work.

Does this http://jsc3d.googlecode.com/svn/trunk/jsc3d/demos/bmw.html works?

The problem is not viewing your online samples, the problem is using your
online samples offline.
Yes, I can view this online sample along with all your online samples without
issue.
I can not get your sample to work on my machine or my web server. Some
component or path is missing.
Maybe the issue could be related to how this portion of the code has been setup:
JSC3D.Viewer.prototype.loadScene = function() {
this.scene = null;
this.isLoaded = false;
if(this.sceneUrl == '')
return false;
var lastSlashAt = this.sceneUrl.lastIndexOf('http://jsc3d.googlecode.com/');
if(lastSlashAt == -1)
lastSlashAt = this.sceneUrl.lastIndexOf('\\');
var fileName = this.sceneUrl.substring(lastSlashAt + 1);
var lastDotAt = fileName.lastIndexOf('.');
if(lastDotAt == -1)
return false;
var fileExtName = fileName.substring(lastDotAt + 1);
var loader = JSC3D.LoaderSelector.getLoader(fileExtName);
if(!loader)
return false;
var self = this;
loader.onload = function(scene) {
self.setupScene(scene);
};
loader.onerror = function(errorMsg) {
self.scene = null;
self.isLoaded = false;
self.isFailed = true;
self.errorMsg = errorMsg;
self.update();
};
loader.onprogress = function(task, prog) {
self.reportProgress(task, prog);
};
loader.onresource = function(resource) {
if((resource instanceof JSC3D.Texture) && self.isMipMappingOn && !resource.hasMipmap())
resource.generateMipmaps();
self.update();
};
loader.loadFromUrl(this.sceneUrl);
return true;
};
...but, we have changed the url http://jsc3d.googlecode.com/ to ours without
any luck.
Any additional help would be great. Ideally, a zipfile with a working example
that works on a different server than yours. This then, will more than likely
work on any server.
Thanks,
Kevin

I don't think the code snippet you posted above is logically correct. This line
var lastSlashAt = this.sceneUrl.lastIndexOf('http://jsc3d.googlecode.com/');
should be
var lastSlashAt = this.sceneUrl.lastIndexOf('/');
Its purpose is to extract the file name and then guess the file type by the
extension. If you changed that it won't work properly.
Additionally, when sending the URL of a model file to jsc3d (through
viewer.setParameter() before initialization or viewer.replaceSceneFromUrl() at
runtime), it's recommended to specify a relative path instead of an absolute
one. The latter may result in an cross-domain issue that makes jsc3d fail to
access the model file.

Thank you for your assistance.
I can get the following attachment to work offline inside Firefox 22 but not IE
10.
Any help would be great!
Thanks,
Kevin

I see. It is relative to a defect of jsc3d's obj loader implementation. It
tends to generate incorrect face indices and lose materials when parsing
obj/mtl files exported by some versions of 3DsMax. These peculiar data make the
browser either do not draw anythig or draw with abnormal long delay. All
depends.
This has already been fixed in the latest repository edition but not made a new
release yet. You can download it using svn tools or from the direct link
http://jsc3d.googlecode.com/svn/trunk/jsc3d/jsc3d.js.
I tested your model using IE9 and a local server (see the attached picture) and
it looks all right.

I do not have any experience in programing and we use joomla for our web site.
It is about 3d scanning and printing. We want to show our scanns in 3D using
jsc3d.
we have copied the jsc3d and all related files under image/test/jsd3d/.... and
our obj file is under image/test/...
I have tried to use the coding:
<!DOCTYPE html>
<html>
<head>
<title>Getting Started with JSC3D</title>
</head>
<body>
<canvas id="cv" width=640 height=480>
It seems you are using an outdated browser that does not support canvas.
</canvas>
<script type="text/javascript" src="image/test/jsc3d/jsc3d.js"></script>
<script type="text/javascript">
var viewer = new JSC3D.Viewer(document.getElementById('cv'));
viewer.setParameter('SceneUrl', 'image/test/test.obj');
viewer.setParameter('ModelColor', '#CAA618');
viewer.setParameter('BackgroundColor1', '#E5D7BA');
viewer.setParameter('BackgroundColor2', '#383840');
viewer.setParameter('RenderMode', 'flat');
viewer.init();
viewer.update();
</script>
</body>
</html>
The only thing happened is that it has created the 640x480 area.
Can you help me with the coding please.??

i'm trying to get your demos to work using the latest release of jsc3d.
neither on my local machine nor on my webserver am i able to load most the
demos--the canvas is drawn fine, but none of the demos that specify a sceneurl
work. the message that is displayed is "failed to load obj file."
with certain demos, like jollyship.html, the model shows up, but these demos
don't have a sceneurl specified.

i solved the problem by making sure the .obj mimetype is able to be served by
the webserver. thanks!
