## Abstract

This paper presents a fast volume rotation technique based
on binary shear-warp factorization. Unlike many acceleration
algorithms this method does not trade image quality for speed
and does not require any specialized hardware either. In order
to skip precisely the empty regions along the rays to be
evaluated a binary volume is generated indicating the
locations of the transparent cells. This mask is rotated by
an incremental binary shear transformation, executing bitwise
boolean operations on integers storing the bits of the binary
volume. The ray casting is accelerated using the transformed
mask and an appropriate lookup-table technique for finding
the first non-transparent cell along each ray.
