Technically speaking, they're both pitch. The difference is in what is being "pitched". In your first example, the panorama is stationary and the viewer / camera is having its pitch altered. In your second example, the panorama itself (assuming a spherical projection) is being rotated. Assuming you're using the viewer / camera as the axis reference for this rotation, it would also be correct to call this a pitch rotation. If you can describe what you're actually looking to achieve, we might have better insight. For example, the first animation shows the effect of cropping the top and bottom of an equirectangular panorama. The second animation is a little confusing since the grid seems to stay locked to the camera, but assuming it's just projecting a camera-space grid onto an invisible spherical panorama that isn't moving, this can be accomplished with the pitch control in Move/Drag tab of the Fast Preview window. Hugin's model considers the virtual camera to be still and the panosphere to rotate around it, but the result is functionally identical. If you're looking to just capture that center band, you could reduce the vertical FOV to suit. --Sean -- 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.
