Hi all,


frightfully bad with maths... but perhaps I could describe my dilemma, and get a bit of specific help?

I have a coordinate system, and then a second system. The scale is the same, but the direction of one axis is inverse to the other, and the position and rotation can not be known in advance.

I can "calibrate" one coordinate system to the other... so that I can take some set of two or more points, and know what that point represents in BOTH systems.

Armed with that information... how can I map any hypothetical point in one system, to the other?

(Apologies if this is not the right location for this kind of question)

Thanks for your kind help,

R
