3D to 2D mapping with camera

OpenGL
1

Hi,

If I have a point, A, in a 3D space <Ax,Ay,Az> relative to a camera that is the origin of the world <0,0,0>. How would it map to the computer screen which is a 2D plane with a different origin?

Thanks in advance.

That would depend on your projection matrix and the view configuration of the screen. This should give you a better idea:
