How do I set the line width in OpenGL relative to the viewing area of a frame buffer?

glLineWidth rasterises the width so it shows as that width on the screen. I want it to be that width on a frame buffer.

Thank you.

Solution

  • Basically, your screen width is a different size from your frame buffer?

    desired_size = size_on_screen * (frame_buffer_width / screen_width)
