Hi,

I am showing the big view (larger then screen). When I do it larger the opengl stop showing the view.
I thing the error is the memory of video card is out of size.

  1. How can I know the memory size of opengl?
  2. If I am use glViewPort on part that showed in screen it low the memory size?

Thank’s
Alexei

    if glGetError(); gives you GL_OUT_OF_MEMORY, then you don’t have enough memory to execute the command.

    Most probably not, unless you’re dealing with extreme width and/or heights.
