I suddenly realize I don't know whether we normally talk about "angle of view" horizontally or diagonally. I'm more comfortable with horizontal. If I'm doing my trig correctly, the width of the field of view matches its distance when the angle of view is 53.13 degrees. If that was the total angle of view of the resulting mosaic, then the X value of each photo would range from -0.5 though +0.5 based on the fraction of full mosiac width that each component photo is off center. For a narrower angle of view, those X numbers would be smaller (as in the test I mentioned in which 0.1 was a "large" value for X). The range -0.5 to 0.5 would be shifted if the anchor image were off center, and could also be increased or decreased if the yaw were nonzero. For a rough understanding of the scale of X, Y have I got that right? -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
