Visualization Options
There is a dialogue window in our software that
contains the controls for setting the type of transparency
and its distribution (Fig. 5). Each fixation adds a certain
amount of transparency in each point of visualization.
However, only the Gaussian distribution covers all the
display, whereas the other distribution types affect only the
area in the vicinity of the fixation. The shapes of influence
for all the distributions available are shown in Fig. 6. In
this figure, the x axis denotes distance from a fixation, and
the y axis denotes influence on the transparency.
