Abstract
A high resolution distortion correction system is provided for an arbitrary projection system. First, a field of view is subdivided into multiple viewports. The multiple subdivided viewports provide a first approximation of the distortion. Polygons that are projected onto a particular subdivided viewport are rendered in a frame buffer and stored in texture memory as an intermediate texture image. The intermediate texture images are subsequently applied to a rendered distortion mesh to generate an output image.
