Well, just subtract the position from the camera's location, slap a
vlength(...) around it, and the resulting float is the distance in POV-Units
from position to location. An example:

#declare Camera_Location = <0,5,10>;
camera{location Camera_Location look_at <0,0,0>}

#declare Position = <4,6,12>;

#declare Distance = vlength(Camera_Location-Position);

Nice animation for a beginner, though the car is a little jerky at the
curves...

Tim
