Abstract
Image data is converted to nonplanar image data for display on a nonplanar display, using a planar image graphics computer system, such as an OpenGL® system, which converts image data to planar image data for display on a planar display. A transformation matrix is obtained from the planar image graphics computer system. A plurality of vertices of the image data are multiplied by the obtained transformation matrix, to produce transformed image data. The transformed image data is nonplanarly distortion corrected to produce nonplanar image data. A passthrough transformation matrix, such as an identity matrix, is provided to the planar image graphics computer system. The nonplanar image data is then input to the planar image graphics computer system for further processing. The nonplanar image data which is processed by the planar image graphics computer system is then displayed on a nonplanar display. Accordingly, the image data is distortion corrected and manipulated as necessary, so that the distortion corrected image data can be applied to a standard planar image graphics computer system for image processing.
