DIVE: Dynamic Inhomogeneous Volumetric Environment for Graphics and Visualization

Abstract:
With the advent of ever-increasing computing power and more advanced data
acquisition technologies, solid geometry has quickly gained popularity as a
natural and intuitive paradigm for representing and modeling three-dimensional
objects in interactive graphics, shape design, physics-based animation,
scientific visualization, and virtual environments.

In this talk, I will articulate our novel spline-based framework for modeling,
manipulating, and visualizing volumetric objects. We have systematically
developed the new Dynamic Inhomogeneous Volumetric Environment, DIVE, which is
founded upon spline-based volumetric implicit functions and powerful
physics-based modeling. This new graphics framework facilitates the flexible
modeling and effective rendering of multi-dimensional, physical attributes
across any volumetric objects. In addition, our spline-based volumetric models
are governed by the principle of dynamics, hence responding to sculpting forces
in a natural and predictable manner. The versatility of our dynamic volumetric
modeling affords users to easily modify both the geometry and the topology of
modeled objects, while the inherent inhomogeneous physical properties can offer
an intuitive interface for direct manipulation. We augment our framework with a
3D haptic interface, further enhancing the realistic manipulation of any modeled
dataset. We also develop the novel Scalar-Field-guided shape Deformation (SFD)
technique for free-form deformation and animation. Throughout my talk, I will
highlight diverse applications including shape design, shape reconstruction,
digital arts, haptic sculpting, computer animation and morphing, and medical
data exploration and visualization through slide shows and video clips.
