Graphics card does not support WebGL

[Vitaly Kheyfets]

Hello,

For some reason, OpenSim says that my graphics card does not support WebGL.

I have the NVIDIA Quadro M2200, which says that it includes WebGL. I also just downloaded the latest drivers and rebooted, but the problem persists.

Please let me know if there is something else I could try.

Thank You,

Vitaly

Hi Vitaly,

The visualization package we use in OpenSim 4.0 is based on WebGL and as such requires the graphics card to support it. We had a few instances where running OpenSim, it reports missing WebGL support. These machines fall into a few categories:
1. Machines with old graphics cards that do not fully support the standard.
2. Machines with 2 graphics cards (one integrated/embedded and the other dedicated). In these cases you need to tell your machine to use the dedicated graphics (details are very much machine/manufacturer dependent).
3. Machines with capable graphics cards that the library mis-identifies or cannot detect.

I suggest you lookup if your graphics card has the latest drivers, and is enabled by default, and is certified as supporting WebGL, if that all holds we can investigate Option 3 above (that the library is more strict than necessary). You may find it helpful to try to open the webpage (https://threejs.org/examples/#webgl_animation_cloth) and see if it displays on your machine since it uses the same library (though a more recent version).

Please let us know what you find out.
Best regards,
-Ayman

Hi Aman,
I have exactly the same issue. My machine is an i3 with Windows 7 and a ATI Fire card, but I can run WebGL on any browser, including the website you mention on your answer to Vitaly. I wonder if there's a way to run OpenSim forcing it to not test for the graphics card? I know there are a lot of cards in the market, but if I could bypass that test, I'm sure it would work.

Update on my previous question

I don't really know if anyone from the project will ever see this, but I'm really puzzled about how Opensim decides the graphics card cannot run WebGL (as it says). I have my card installed with the latest drive for Windows 7. I tried all the animations at threejs.org, as suggested by Ayman, and they all run flawlwess, with great texture, on Edge and Chrome. The thing that puzzles me most is I took a look at OpenSim code and it seems to me you guys are using simbody-visualizer to render the models, so I tried running it directly from the command line, and it runs. If I disable my ATI FireGL card and use the on board card, then simbody-visualizer complains about not being able to run on that "ancient" system. So everything seems fine, I run all kinds of 3D stuff, from Solidworks to games, DirectX or OpenGL and the only thing not working right now is OpenSim. Am I missing anything here? Is Opensim really that demanding or is it a bug on the code identification of cards?
I attached a screenshot that shows simbody-visualizer running and the result from OpenGL Extensions Viewer, showing the OpenGL 2.1 (does OpenSim need 3+?)
Any help would be pretty much appreciated.
