Although graphics hardware is well suited to accelerate texture-based volume rendering methods for volume visualization of uniform grids, hardware acceleration is less easily exploited for texture-based volume rendering more complex meshes.Meteorological simulation and measurement data are gridded according to the requirements of the simulation and/or the measurement system.Therefore, an intermediate resampling step is often necessary for texture-based volume rendering, eliminating any potential benefits offered by the original grid structure and often introducing resampling errors. This article presents a novel, texture-based volume rendering architecture applicable to many nonuniform meshes, which avoids the need for resampling or for the visibility sorting typically required for tetrahedral meshes. Advanced lighting methods in texture-based volume rendering improve the perception of 3D structure in the volume.Functional approximations of the mapping from world space to computational space, performed per-fragment on programmable graphics hardware, allows application of these advanced techniques to many important grids in meteorological research at interactive rates.
