[edit] Summary

Diagram of how perspective transform works in computer graphics

To determine which screen x coordinate corresponds to a point at Ax,Az multiply the point coordinates by:

$screen\ x\ coordinate\ (Bx)\ =\ model\ x\ coordinate\ (Ax) \times \frac{distance\ from\ eye\ to\ screen\ (Bz)}{distance\ from\ eye\ to\ point\ (Az)}$

the same works for the screen y coordinate:

$screen\ y\ coordinate\ (By)\ =\ model\ y\ coordinate\ (Ay) \times \frac{distance\ from\ eye\ to\ screen\ (Bz)}{distance\ from\ eye\ to\ point\ (Az)}$
