Volume Stylizer: Tomography-based Volume Painting
Volumetric phenomena are an integral part of standard
rendering, yet, no suitable tools to edit characteristic
properties are available so far. Either simulation results
are used directly, or modifications are high-level, e.g.,
noise functions to influence appearance. Intuitive artistic
control is not possible.
We propose a solution to stylize single-scattering
volumetric effects. Emission, scattering and extinction
become amenable to artistic control while preserving a
smooth and coherent appearance when changing the
viewpoint. Our approach lets the user define a number of
target views to be matched when observing the volume from
this perspective. Via an analysis of the volumetric
rendering equation, we can show how to link this problem to
tomographic reconstruction.

Abstract
After decades of research on digital representations of
material and object appearance, computer graphics has more
recently turned to the problem of creating physical
artifacts with controllable appearance characteristics.
While this work has mostly progressed in two parallel
streams – display technologies as well as novel fabrication
processes – we believe there is a large overlap and the
potential for synergies between these two approaches. In
this report, we summarize research efforts from the worlds
of fabrication display, and categorize the different
approaches into a common taxonomy. We believe that this
report can serve as a basis for systematic exploration of
the design space in future research.
