Re: [Public WebGL] Multiple viewports/contexts



Thanks Chris,

Using mulitple viewports is certainly how I would have done it in a desktop app - I was just checking in case there was some issue with webgl that I wasn't aware of.

Regards

Alan

Multiple viewports in the same context is almost certainly the best option. Multiple contexts will involve memory/resource usage that's a direct multiple of the number of contexts you have, becuase you can't share any GL resources across different WebGL contexts.
I agree. Not only is there the resource issue, but many OpenGL implementations incur a large cost for switching contexts, so the multiple context approach would probably be slower as well.
