Thanks Carl & Joachim, Yes, I do have a tripod, and I get the general idea of anchoring one image that has land and sky in it so the hand-parameterized sky images stay anchored.
However, I'm trying to understand roll, pitch and yaw. Where is the (0,0,0) point for anchoring the frame of reference of the coordinate system? Is it somehow, "The location of the anchor image" (assuming that r,p,y for the anchor image are left at zero)? Or is it somehow the back-projected setup of where the tripod would have been to shoot the anchor image? Or are those the same thing? I guess what I'm asking is, if I could measure how many degrees I've rotated my tripod/pano head horizontally from some anchor point, do I put that number in directly as the yaw, or does it have to be transformed in some way? I guess I usually think of a photo as a 2D projection that "lives on a plane out there in space somewhere where I see all the stuff in the photo." But in reality, a photo is probably a 2D projection of all that stuff onto a plane at the nodal point of the lens. Is that correct? [Does my question even make sense?] Thanks, Rodney On Sep 2, 1:42 pm, "J.
