Why does the viewport depend on the method to get it ?
I am using the GetMousePos and then GetScreenPixelColor to pick up the color in a SColorSpectrum. It works very well but i have gathered 3 different methods of getting the viewport and they give very different results:
I have no problem since the last method works all right, but i am very curious about the results of the first two methods.
Anyone would care to explain what exactly goes on in the 3 methods ?
