3d multimarker setup

[sircedric4]

Its a shame I can't edit a previous post instead of double posting but I think I know what I want to do but need to know how to do a fairly simple transform. Does vizmat or some other function have a means to make one object the new coordinate system origin, and then when I call getPosition for the other objects they will be in relation to that new origin?

Does anyone know how to do that? I think if I can set one of my markers to be the origin of the system and then just poll my other markers positions based off that new origin then I will have most of my problem licked.
