ABSTRACT

 

For the local TV presentation of weather forecast data it is important to have high-quality and fast visualisation of clouds. In this paper we present surface-based methods for the high performance visualisation of clouds from data produced by a routine meteorological weather simulation. Isosurfaces, which are originally too coarse because of the data grid resolution are refined and deformed. The refined geometry is used for a light simulation and transparency computation.

 

Keywords: Meteorological visualisation, cloud modelling and visualisation, surface refinement.
