Splatting is a popular direct volume rendering algorithm. However, the algorithm
does not correctly render cases where the volume sampling rate is higher than
the image sampling rate (e.g. more than one voxel maps into a pixel). This
situation arises with orthographic projections of high-resolution volumes, as
well as with perspective projections of volumes of any resolution. The result is
potentially severe spatial and temporal aliasing artifacts. Some volume
ray-casting algorithms avoid these artifacts by employing reconstruction kernels
which vary in width as the rays diverge. Unlike ray-casting algorithms, existing
splatting algorithms do not have an equivalent mechanism for avoiding these
artifacts. In this paper we propose such a mechanism, which delivers
high-quality splatted images and has the potential for a very efficient hardware
implementation.
