[osg-users] Draw thread per opengl context instead of per GraphicsContext

[Ben Meijering]

Hi Robert,

Thanks again for your quick response.

Isn't an opengl context already used by multiple windows when you use GraphicsContext::Traits::sharedContext ?

I also came across the following function:

BOOL WINAPI wglMakeCurrent(
   HDC   hdc,
   HGLRC hglrc
);

A window device context can be specified here, so it would seem that you can change the window.

I also came across the following:

https://blog.gvnott.com/some-usefull-facts-about-multipul-opengl-contexts/

This also seems to state that a single opengl context can be used to render to multiple windows.

Thank you!

Cheers,

Ben
