Swedish Meteorological and Hydrological Institute, smhi, runs a network of 12 weather radars together with the Swedish Armed Forces. Data from them are used for short term weather forecasting and analysis; for detecting wind speeds and directions as well as rain fall amounts. The radars deliver data in the form of 3D polar volumes four times an hour, day and night, every day of the year. In order to
meet the demand for a user friendly tool to visualize and analyse the data, the development of a software system called rave (which is an
abbreviation for Radar Analysis and Visualization Environment) was initiated in 1996. From the beginning rave was designed to, among
other things, “create and visualize arbitrary 2D products based on 3D data” and to be able to “render 3D views of polar and cartesian volume data with and without backdrops” (Bolin & Michelson, 1996). During 1997 a first version of rave was implemented that included basic functionality but it was not able to render any 3D views - neither is the current version of rave. This project aims to fill this hole.
