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 transparency computation methods for the high performance visualisation of clouds from data produced by a routine meteorological weather simulation. In contrast to the state-of-the-art volume cloud visualisation we use only hardware-supported polygon-based transparency computation.
