through the model domain.

(How to control
pathline display)
- The pathline is colored by using a red-to-blue spectrum to
indicate a range of travel time. Either red or blue may serve as the early
time. Travel times outside the range are clamped to the corresponding endpoint color.
- Thresholding may be applied to show only
those pathline segments for which the travel time is within a specified range.
