Get target point from Viewpoint3D

[iscariot]

How can I get the target point as array from Viewpoint3D? does Catia automation already have a method for this? I don't find it
Having GetOrigin, GetSightDirection , FocusDistance I should be able to get the target point but I forgot all my algebra from a long time ago Any mathematician around?

With other words, having a point P1 coordinates, a vector pointing to a second point P2 and the distance between P1 and P2, how can I calculate the coordinates of point P2?

 

[iscariot]

xTarget = xOrigin + dFocusDistance*xSightDirection
yTarget = yOrigin + dFocusDistance*ySightDirection
zTarget = zOrigin + dFocusDistance*zSightDirection

Is it like this?
