Metaphors for Visualization
This work investigates the use of several common objects
such as spray cans, flashlights, carving knives, and others
as metaphors for visualization.
The motivation behind this work is to provide an intuitive
and natural 3D interface such that users will view these
objects as tools during the visualization process.
To help achieve this goal,
the selection of the object tools are derived from expressions
commonly used during visualization.
let's paint this (iso)surface red;
cut away the front part of that volume;
look at it from this angle;
you get similar effects from an x-ray photo;
and let's explore this data set.
In this work,
we also extend the metaphor of cutting planes to allow
users to carve non-planar cross-sectional cuts through their data sets.
This extension will directly benefit applications such as
medical visualization where one might want to generate curved
coronal cross-sections of lumbar spines;
and in oceanography where one might want to compare
numerical model output against data obtained along
non-planar ship tracks.
