Adding a new solid type: Design disk record
define rt_xxx_internal --- parameters for solid define xxx_specific --- raytracing form, possibly w/precomuted terms define rt_xxx_parse --- struct bu_structparse for "db get", "db adjust", ...
code import/export/describe/print/ifree/plot/prep/shot/curve/uv/tess
edit db.h add solidrec s_type define edit rtgeom.h to add rt_xxx_internal edit table.c: RT_DECLARE_INTERFACE() struct rt_functab entry rt_id_solid() edit raytrace.h to make ID_XXX, increment ID_MAXIMUM edit db_scan.c to add the new solid to db_scan() edit Makefile.am to add g_xxx.c to compile
Then: go to src/libwdb and create mk_xxx() routine go to src/conv and edit g2asc.c and asc2g.c to support the new solid go to src/librt and edit tcl.c to add the new solid to rt_solid_type_lookup[] also add the interface table and to rt_id_solid() in table.c go to src/mged and create the edit support
