Illustrative
Graphics & Visualization Program
(phase #4) In the
early stages of any modeling activity,
users collaboratively build a range of
conceptual models, which help formulate
ideas, suggest possible solutions, and
make important decisions that affect
subsequent modeling stages. Conceptual
models are commonly represented as
hand-made sketches and renderings (Fig.
1a), providing rich visual references for
exploring the uncertainties and helping on
the depiction of a more interpretive,
approximated version of the intended
model. Computational
tools proposed to aid the user in this
process have their foundations in three
computer graphics and visualization
fields: (1)
Sketch-based
interfaces and
modeling
(SBIM); (2)
Non-photorealistic
rendering
(NPR); and (3)
Illustrative
visualization
(IVis). These areas introduced a new
paradigm that leverages the traditional
illustrator’s fundamental and applied
drawing and rendering skills, allowing
users to build and visualize models more
intuitively and to gain new insights into
exploring their uncertainties. In phase
#4 of our program in Illustrative Graphics
& Visualization, we are seeking to
address fundamental research problems in
SBIM, NPR/IVis identified in our ongoing
work on applying interactive modeling and
visualization to geoscience; and also
inspired by examples of traditional
geological sketching, rendering, and
illustration practices and examples we
observed over the years. We are focusing
on three interrelated fundamental research
themes and related problems: ---Collaboration: |
