[Ctk-developers] CommonGL idea

[Steve Pieper]

Hi VTKers and CTKers -

Nicolas and the XTK team [1,2] have been working on some upgrades to XTK's
WebGL and volume rendering and I've been helping a bit while also playing
with GLSL shaders in VTK.

It seems to us that there's an opportunity to write the GLSL code in a way
that would be usable in both the traditional desktop and the web/embedded
use cases.

Granted OpenGL != WebGL but the shaders are close enough that we think it's
feasible to create a resource we're calling CommonGL.

Anyway I wrote up some notes and ideas [2] and would appreciate any
feedback or help.

Best,
Steve
