Ray tracing of point models (2007)
In this section, the basic ray-surface intersection algorithm based on this surface definition will be discussed. Together, we introduce extensions to handle sharp features such as edges and corners...
Spectropolarimetry of the 3.4 micron absorption feature in NGC 1068 (2006)
Mason, R. E., Wright, G. S., Adamson, A., Pendleton, Y.
In order to test the silicate-core/organic-mantle model of galactic interstellar dust, we have performed spectropolarimetry of the 3.4 micron C-H bond stretch that is characteristic of aliphatic...
Infrared observations of the 2006 outburst of the recurrent nova RS Ophiuchi: the early phase (2006)
Evans, A., Kerr, T., Yang, Bin, Matsuoka, Y., Tsuzuki, Y., Bode, M. F., ...
We present infrared spectroscopy of the recurrent nova RS Ophiuchi, obtained 11.81, 20.75 and 55.71 days following its 2006 eruption. The spectra are dominated by hydrogen recombination lines,...

Anisotropic point set surfaces (2006)
Point Set Surfaces define smooth surfaces from regular samples based on weighted averaging of the points. Because weighting is done based on a spatial scale parameter, point set surfaces apply...
Point-sampled cell complexes (2006)
A piecewise smooth surface, possibly with boundaries, sharp edges, corners, or other features is defined by a set of samples. The basic idea is to model surface patches, curve segments and points...

Point Set Surfaces define smooth surfaces from regular samples based on weighted averaging of the points. Because weighting is done based on a spatial scale parameter, point set surfaces apply...
Adaptive sampling of intersectable models exploiting image and object-space coherence (2005)
Adamson, A., Alexa, M., Nealen, A.
We present a sampling strategy and rendering framework for intersectable models, whose surface is implicitly defined by a black box intersection test that provides the location and normal of the...
Hydrocarbon Dust Absorption in Seyfert Galaxies and ULIRGs (2004)
Mason, R. E., Wright, G., Pendleton, Y., Adamson, A.
We present new spectroscopic observations of the 3.4 micron absorption feature in the Seyfert galaxies, NGC1068 and NGC7674, and the ultraluminous infrared galaxy, IRAS08572+3915. A signature of C-H...
On normals and projection operators for surfaces defined by point sets (2004)
Levin's MLS projection operator allows defining a surface from a set of points and represents a versatile procedure to generate points on this surface. Practical problems of MLS surfaces are a...
Approximating bounded, non-orientable surfaces from points (2004)
