It provides both color-shaded surface and simple volumetric rendering in either index or true color. For shaded surface rendering, the Poly routines first compute the polygon set that describes a desired surface within the three-dimensional data volume. These polygons are then rendered as continuously shaded surfaces by the Paint routines.
Paint contains a wide variety of options that control the lighting, viewing, and shading.
Objects rendered volumetrically may be viewed along with shaded surfaces with proper hidden surface or volume removal. The Cray Research version of PolyPaint has a command line interface which can be used interactively or can be called from Fortran. PolyPaint reads netCDF data files and writes net CDF polygon files and NRIF raster files. PolyPaint is designed to be portable and require no special graphics hardware.
