opengl draw lines doubt

Hello,[SUB][/SUB]

I was creating a rectangle and i saw that the left bottom corner does not had a filled pixel. To correct it i drawed a pixel with GL_POINTS on the left bottom corner. Why this corner didnt display that pixel? I am using opengl 3.3 core profile under windows 7 with glfw framework.

Thank you,

Where one line ends another should start. Do not start or end two lines at the same spot, I guess, and the extra pixel will not be needed - just reverse direction of some lines.

Thank you but didn’t work!

You are welcome, but it should. :slight_smile:
Would you post a line-drawing part of code?

Use GL_LINE_LOOP if the start and end points are the same.
