Abstract

The visualization of scientific data requires the translation of that data into a format suitable for rendering. As the number of supercomputing simulations and the number of available renderers increases, the magnitude of this translation problem increases as well. A potential solution is the use of a standard format for 3D models, which (ideally) all simulations can generate and all renderers render. The P3D model metafile is such a format, based upon Common Lisp with extensions for geometry. This method provides easy representation of directed acyclic graphs and complete programmability to facilitate interfaces to new model generators, without the introduction of a new and unfamiliar language.
