I try to use the glCopyTexImage2D in cpp (with a GeForce2go, detonator 23.11) but my texture wasn’t filled with the framebuffer.
i made this :
(init my_current_texture with white color)
(rendering a view of my scene)
(changing camera view)
(display another view of my scene with my_current_texture)
##error my_current_texture was filled in black !
I also use glCopyTexSubImage2D (more speed on nvidia card) but with the same result.
Should I pay attention to SwapBuffers order?
I didn’t found some example on the web.
Does anybody have a sample of code or idea ?
