Hi, I'm trying to create a spherical panorama viewer that doesn't use any sort of OpenGL / texture memory in the process. I would like to be able to start with a rectangular image (standard spherical map, pitch = vertical, yaw = horizontal). Then I want to be able to fill in a viewing window (640x480) with the corrected view of the panorama according to the view's field of view, yaw, pitch, and roll values. I've looked into some methods for handling this sort of thing, but my results have been much too slow (about 6 fps on a P4 1.5G). I was wondering if there are any mathematical shortcuts or warping algorithms that could help me speed up my process. Can anyone help me get started? Thanks, Trent
