Useful for server-side WebGL use cases
From 2 comments
I know that some medical image viewers use server side rendering for segmented volumes. Such tasks are computationally intensive and usually involves very large datasets. With…

It is a little buggy for production use at the moment. A bunch of basic things are broken, but we are working on fixing those issues in the near term:…

Server-side rendering and streaming may be slow or heavy per client
From 1 comment
You could, but it would be slow, or at least pretty heavy per client. That said if you have a beefy enough server I suppose it might work.

glReadPixels causes pipeline stalls, hurting performance
From 1 comment
That's a really bad idea, glReadPixels is usually a full pipeline flush + read back and stall which kills perf for all sorts of reasons.

Direct access to graphics drivers and IO from Node.js
From 1 comment
It would be cool if you could talk to the graphics driver and other IO devices directly from NodeJS. I guess it would require a layer for cross platform standardization. But…

Questions
Is it hardware accelerated?
From 1 comment
And, if so, is it hardware accelerated or a software implementation? Edit: And, how many concurrent context could it support?

Can any WebGL code be rendered server side and streamed?
From 1 comment
Does this mean we can basically render any WebGL code server side and effectively stream the output?

node-webgl (OpenGL wrapper)
From 1 comment
Funny they mention a project called "node-webgl" being an opengl wrapper. Seems like they should have traded project names, since "headless-gl" sounds like an OpenGL thing and…
