3d orthogonal projection on a plane

hi,
I have a point in 3d P(x,y,z) and a plane of view Ax+By+Cz+d=0 . A point in plane is E.Now i want to project that 3d point to that plane and get 2d coordinates of the projected point relative to the point E.

P = 3d point

p.s. what i am doing right now is to get nearest point in plane from point P.then i subtract that point to E.I suspect that this is right ???

please help me.
Thanks.

[color=#000000]The vector is perpendicular to the plane , use the equation of the parametric line and compute where this line intersects the ? plane.[/color]
