Rendering to Multiple Windows using glut

OpenGL OpenGL: Advanced Coding

If I want to use the same texture in 2 diferent glut windows, I need to load the texture twice (one for each window)?

There’s a way to use a FBO rendered texture in another window directly?

Thanks in advance.

Not possible with GLUT, but apparently doable with freeglut with :
glutSetOption(GLUT_RENDERING_CONTEXT ,GLUT_USE_CURRENT_CONTEXT);

ZbuffeR, do you if there is an implementation of freeglut for the Microsoft Windows?

I need to have a project that can be compiled both in linux and windows.

Search on this page for “Windows binaries”. Apparently so.
