Which library allows you to open multiple gl windowes

OpenGL
1

I need to open multiple opengl windowes under X (Linux).

SDL is nice, but it only supports one window.

I think fltk at least supports this… any others?

And then… Is is possible to share same textures between different gl contexts (windowes) ?

Thanks.

You can do this directly with Motif/X.

Yes. See glXCreateNewContext and p663 of OpenGL redbook.

Alternatively, you can glScissor() to split your one window up into multiple (user-controlled) sub-windows. If you want to go full-screen, you’ll need to do this anyway.

You can also do a new glViewport() for each one if you like.

Thanks for the replies. Time to do some testing…
