Since the original paper of Lacroute and Levoy [9], where the shear-warp factorization was also shown for perspective projections, a lot of work has been carried out using the shear-warp factorization with parallel projections. However, none of it has proved or improved the algorithm for the perspective projection. Also in Lacroute's Volpack library, the perspective shear-warp volume rendering algorithm is missing.This paper reports on an implementation of the perspective shear-warp algorithm… CONTINUE READING
