[Bf-committers] [GSoC] OpenGL 2D Drawing API

[Mike Erwin]

Hi Chris, welcome!

I wrote that caveat about prior work, but not the original project idea.
Really it's "ongoing work" which is mostly focused on 3D, and that 2D
should share some inner workings instead of totally diverging. One of the
technical goals for Blender 2.8 is a GPU API that the rest of our code can
call into, that is performant, correct and easier to use. You could
call this an abstraction layer but we're not trying to wrap all of OpenGL
-- just the parts we want to use.

Anyone working on a clean 2D UI drawing API should be aware of how that
would fit into and affect the overall GPU API. Which is exactly what
mentors are for! Put together a proposal early then we can give more
specific feedback. You can revise it up to the deadline.

Also you should check out non-Blender prior work such as Quartz, Skia,
NV_path_rendering. Our 2D API doesn't need to be as complete as those since
it's for our internal use.

OpenGL 3.2 core profile is our target for future work, so focus on that.
