Khronos Notes 8/28/2025

 

I am unclear about what is going on with Khronos especially as it affects OpenXR and WebGL and the various browsers.  

1. Khronos appears to have 23 active standards including OpenXR and WebGL

2. Each of these standards has a working group.  Most groups are 4 people or less.  All of the members of the group are affiliated with a company that is a member.  However these groups are tiny and probably do not represent the "real" working or advisory groups, which are not listed on their web site.  There are no individuals listed.

3. There are 4 levels of membership for companies and 1 for academia.  Costs per year vary from $90,000, $22,000, $9,000 to $4,000 plus.  Academic membership is $1,000 per year.  There is no way for an individual to join.  NYU is not a member nor is UC, CMU, MIT or Stanford.

4. As all members of the working groups are by definition employed by a member company, I do not know what it means for them to be a "volunteer".  

5. I know that the working group for OpenGL was much larger than anything mentioned here, on the order of maybe 30-50 members so obviously there is something I do not understand here.

6. Meta is a contributing member, but I am told is not a supporter of OpenXR.

7. It is not clear whether WebGL is a volunteer or a supported activity at each of the various browser companies.  Given the potential for performance and stability issues it seems difficult to believe that it would be a pure open source, volunteer activity but maybe it is.  WebGL is essentially a repurposing of OpenGL ES 2.0 and 3.0 so maybe there are robust implementations that can be trivially incorporated.

8. It is not possible for an individual to be a member of Khronos.  It is possible that they can be invited onto a working group (or other advisory group).

To be updated.
