This paper explores two general methods for incorporating volumetric
uncertainty information in direct volume rendering. The goal is to produce volume
rendered images that depict regions of high (or low) uncertainty in the data.
The first method involves incorporating the uncertainty information directly into
the volume rendering equation. The second method involves post-processing information
of volume rendered images to composite uncertainty information. We
present some initial findings on what mappings provide qualitatively satisfactory
results and what mappings do not. Results are considered satisfactory if the user
can identify regions of high or low uncertainty in the rendered image. We also
discuss the advantages and disadvantages of both approaches.
