Wow, this is awesome. I made a WebGL image editor as a side project (http://photogl.net) so I know how much work it takes.
I'm impressed.
I'll be really excited if/when you get 16bit RAW working.
Thanks! Your work actually inspired the team a lot and made us think what we are doing are in fact possible. The saving/outputting part of photogl.net seems to be prone to crash. Are you planning to continue the project at anytime? If you're interested in chatting, please reach out to xiao@polarr.co!
