  abstract =   "We present Volume dots (Vots), a new primitive for
               volumetric data modelling, processing, and rendering. Vots
               are a point-based representation of volumetric data. An
               individual Vot is specified by the coefficients of a Taylor
               series expansion, i.e. the function value and higher order
               derivatives at a specific point. A Vot does not only
               represent a single sample point, it represents the
               underlying function within a region. With the Vots
               representation we have a more intuitive and high-level
               description of the volume data. This allows direct
               analytical examination and manipulation of volumetric
               datasets. Vots enable the representation of the underlying
               scalar function with specified precision. User-centric
               importance sampling is also possible, i.e., unimportant
               volume parts are still present but represented with just
               very few Vots. As proof of concept, we show Maximum
               Intensity Projection based on Vots.",
