stl-g — Stereolithography Translator (STL to BRL-CAD)


stl-g [-db ] [-i initial_ident] [-I constant_ident] [-m material_code] [-N forced_name] [-c units] [-t tolerance] [-x RT_DEBUG_FLAG] file.stl file.g


stl-g converts the specified file.stl to a BRL-CAD file.g file. Use the -b option if you have a binary STL file (the default is ASCII). The -d option prints debugging information. The -c option specifies the units that are used in the STL file. The units string may be "mm", "in", "ft", ... (default is "mm"). The -t option specifies a tolerance distance (in mm) such that any two vertices within tolerance distance of each other are treated as the same vertex. The -i option sets the starting ident number for the regions created. As each new region is created, this number will be incremented before assigning the next ident number (conflicts with -I ). The -I option sets a constant ident number that will be assigned to all the regions created (conflicts with -i ). The -m option sets a material code that will be assigned to all the regions created (default is 1). The -N option sets a name for the resulting BRL-CAD object. STL files typically do not contain any object names. The -x option sets an RT debug flag (see raytrace.h). The file.stl file is expected to be a stereolithography file.
