[X3D-Public] How to get X3DOM working?

Wed Jun 27 04:05:20 PDT 2012

Hello John and all,

A bit off-topic, a newbie question. I cannot view the X3DOM examples you are posting; can you please advise me what should I do?

I am on Windows 7, the latest Flash Player 11 is installed. The "Browser support" page:
http://www.x3dom.org/?page_id=9
says "Firefox supports WebGL natively".

Today I installed the latest version of Firefox, but your examples don't work. For instance:
http://coderextreme.net/roses/x3dom/bubbles.xhtml
shows a "Bubbles" title and nothing else, blank page below.

http://www.everyday3d.com/j3d/demo/004_Glass.html
displays an error message "Oh no! Your browser or GPU does not seem to like WebGL. Click here to learn more". The auto-detection page indeed says that the browser doesn't support WebGL. (Is WebGL the same as X3DOM?)

On the other hand, the standard examples work for me:
http://x3dom.org/x3dom/example/x3dom_helloWorld.html
works perfectly both in Firefox and IE.

When I downloaded the standard example to my computer, it did not work. Recently I needed to test a scene in X3DOM, and the only way to launch my own file was to set up a "web server" which fetched files from my local folder. Seems like it works only in a HTTP connection?

Also, I noticed that the standard examples contain a .swf file which is crucial for them to work. What is actually running/rendering X3DOM: the browser itself or a script in the .swf file? What should I do for my Firefox to support X3DOM natively as it should?

                                                                                          Sergey Bederov

Here's some versions of this, thanks everyone for their help

http://coderextreme.net/roses/x3dom/bubbles.xhtml (thanks Mick)
http://coderextreme.net/roses/x3dom/bubbles2.xhtml (my attempt--still buggy)
http://coderextreme.net/roses/x3dom/bubbles3.xhtml (thanks Mick)
http://coderextreme.net/roses/x3dom/bubbles4.xhtml (thanks Mick)
Thanks Mick, Yvonne and Bartek, for your shading expertise!

John

Okay, this appears to be the best version so far, but the sphere doesn't change when the camera changes.  http://coderextreme.net/roses/x3dom/flowers5.xhtml

Okay, perhaps http://coderextreme.net/roses/x3dom/flowers6.xhtml will work if we somehow include uEyePosition?  How does one pull in the eye position into a shader?

Time to do some searching.

Here's where I've buggered it all up again, trying to get back to something similar to what the original scene did.  Help!  flowers5.xhtml should still work for comparison.

Here's the shader in the original scene, you can look down at the skull and see the change.   I will work on getting the right dispersion colors.

Here's my current version; http://coderextreme.net/roses/x3dom/flowers5.xhtml

If there sphere is supposed to be like glass, why does it show dark if you look up at the sky?  If you use the indexed face set instead, you can see the steps through the surface no matter which way you look.

I will keep looking into this.

Thanks,

John

Find attached a working version.

Note that the shaders aren't working due to missing/hardcoded fields, I believe.  What mechanism do I use to send the matrices, etc to the fields?  I'm assuming I use routes or something like that.  Some assistance would be welcome (what nodes do I get the matrices from?).

Thanks,

John
