Re: [Public WebGL] Silverlight 3D



Out of curiosity, I tried one of the Silverlight3D demos with the latest Silverlight plugin:
http://david.blob.core.windows.net/babylon/Babylon.html

Immediately I got this error from the app:

Error during initialization: Hardware rendering is disabled by security reason.

Please right click on the silverligt plugin, go to permissions tab and allow 3D for this application.


I appears that even Silverlight still surfers from DoS issue.
I'm sure there was a lot of discussion about DoS already but how serious it actually is?

From my understanding DoS is pretty benign and it can happen for two reasons:
  1. User without knowledge starts a WebGL app that is way to heavy for his/her GPU.
    (this can be fixed by app developers using smart hardware detection)
  2. User loads a malicious script on a sketchy malicious website.
    (user learns not to visit that website again)
It seems like DoS is more of a trap then an attack and it can't really harm any human being. Some of the DoS arguments against WebGL sound like DoS can cause a nuclear reactor meltdown. Is that really the case? Whats the worse that can happen?

Sounds like good news to me. Exposing 3D in any form (fixed function or programmable) brings the DoS issue. So, either Microsoft has solved it and we can apply the same solution to WebGL. Or else they don't believe it's a problem (since there's not much point in DoSing a user's machine).  It means Microsoft has no more excuse not to ship WebGL in IE.

Well ahead?? No plugin? Cross platform?

For what it's worth, win8 with Silverlight just works for shader based 3D in the browser.  With respect to tablets, it appears microsoft is well ahead of webgl for shader based 3D graphics.
