abstract = "Ray-casting implementations require that the connectivity between
the cells of the dataset to be explicitly computed and kept in
memory. This constitutes a huge obstacle for obtaining real-time
rendering for very large models. In this paper, we address this
problem by introducing a new implementation of the ray-casting
algorithm for irregular datasets. Our implementation optimizes the
memory usage of past implementations by exploring ray coherence.
The idea is to keep in main memory the information of the faces
traversed by the ray cast through every pixel under the projection
of a visible face. Our results show that exploring pixel coherence
reduces considerably the memory usage, while keeping the
performance of our algorithm competitive with the fastest previous
ones.",
