Three-Dimensional Kaleidoscopic Imaging
Three-dimensional kaleidoscopic imaging, a promising alternative for recording multi-view imagery. The main limitation of multi-view reconstruction techniques is the limited number of views that are available from multi-camera systems, especially for dynamic scenes. Our new system is based on imaging an object inside a kaleidoscopic mirror system. We show that this approach can generate a large number of high-quality views well distributed over the hemisphere surrounding the object in a single shot. In comparison to existing multi-view systems, our method offers a number of advantages: it is possible to operate with a single camera, the individual views are perfectly synchronized, and they have the same radiometric and colorimetric properties. We describe the setup both theoretically, and provide methods for a practical implementation. Enabling interfacing to standard multi-view algorithms for further processing is an important goal of our techniques.

Volume Stylizer: Tomography-based Volume Painting
I3D 2013
Abstract
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.
