Abstract
The vast capabilities available in scientific computing today enable
scientists to simulate phenomena with ever increasing the size and
complexity to the point where visualization capabilities have had a
difficult time keeping pace. Many approaches have attempted to address this
problem in one way or another. Almost without exception, these approaches
begin in the standard toolbox, simply selecting an orthographic and
perspective camera model for visualizing the data. It has become
increasingly difficult however to comprehensively represent these vast
datasets within a single image using one of these conventional camera models
because of complex occlusions and large variation in the scale of structures
of interest.
In this talk, I will discuss my past and present research in camera model
design, a new problem solving paradigm in visualization which advocates for
designing camera models that best suit a particular application and optimize
dynamically according to the data currently being sampled. While the
conventional camera models are rigid and have a limited capability, camera
model design is a flexible framework for creating cameras that produce
images with multiple viewpoints and variable sampling rates. The images
created with camera model design carry many of the benefits of those created
using conventional cameras as well. The images generated using camera model
design have a single layer, are continuous and non-redundant, and are
computed efficiently enabling interactive visualizations.
