First, sorry about my english, but i hope you will understand me.

I need the correct mathematical Calculation about the ammout of Pixel. When i transform a plain with -z, then the ammount of pixel decrease. Okay. I understand this. But how calculate OpenGL the ammount of Pixel for the correct perspective. When i start with different x-y coordinates, then it will be different, than i start in x=y=0. The Calculation must depend with x and y Startccordinates.

Please help me. I have to know this.

Thank you for your help.
