Fig. 4 8x Magnification Trilinear

[15]. Our implementation on the MasPar allows rendering with changing viewpoints of five frames/second and two frames/sec-ond for higher quality trilinear reconstruction on 128x128x128 byte volumes. This improves on previous results [2][3] [9][10][12] because of the better filters used, and we discussed the filter differences. Straight forward extensions to our techniques include coher-ency adaptations such as adaptive ray termination and adaptive quadrature. Perspective projection can be added as a follow on warp to the permutation warp for two passes versus four of [12]. The MasPar implementation can also be modified to up sample or down sample, least expensively as an up sample of the transformed image or down sample while warping. Our new decomposition will be useful for 6 pass pure shear multipass approaches versus eight passes [9].
