abstract = {Aurora borealis and Aurora australis are light emissions due to
energized electrons originating in the Sun. As part of the dynamic
processes in the Sun solar flares are created. These flares create
plasma forming the so-called solar wind. When the solar wind
interacts with the Earth’s magnetic field it distorts the field
and forms a type of bow-shock compressing the field sunwards and
elongating the field on the opposite side of the Sun. The
interface between the solar wind and the Earth’s magnetic field is
called the magnetopause and the interior of the distorted field,
the magnetosphere. The auroral phenomena, or the so-called
Northern Lights and Southern Lights, are night sky light shows
resulting from the channeling of energized electrons in Earth’s
magnetosphere into the upper atmosphere. The aim of this paper is
to use non-photorealistic rendering techniques to visualize these
phenomena. In this paper we describe a new approach to visualize
these phenomena using a pipeline of procedures processing
simulated or real scientific auroral data. The pipeline involves
particle decimation, 3D surface extraction, MR filter
applications, and isocurves extraction. Alternative
nonphotorealistic rendering techniques are also introduced. A
rendered sequence of images is provided illustrating the result.},
