New primitives can be created and inserted into the database using the in command. Note that the database must be opened before insertion can take place: Types of primitives Arbitrary polyhedron /arb8/ - arbitrary polyhedron with 8 vertices /arb7/ - arbitrary polyhedron with 7 vertices /arb6/ - arbitrary polyhedron with 6 vertices /arb5/ - arbitrary polyhedron with 5 vertices /arb4/ - arbitrary polyhedron with 4 vertices /arbn/ - arbitrary polyhedron with n vertices /box/ - arbitrary polyhedron (vertex and three vectors) /rpp/ - rectangular parallelepiped (cuboid) Ellipsoid /ell/ - ellipsoid (centre and three semi-axes) /ell1/ - ellipsoid (centre, one semi-axes, radius of revolution) /ellg/ - ellipsoid (foci and chord length) /sph/ - spherical ellipsoid Truncated general cone /rec/ - truncated general cone (right elliptical cylinder) /tec/ - truncated general cone (top radii scaled from base radii) /tgc/ - truncated general cone (general form) /trc/ - truncated general cone (truncated right circular cone) /rcc/ - truncated general cone (right circular cylinder) Other primitives /ars/ - arbitrary faceted solid /bot/ - bag of triangles /ebm/ - extruded bitmap /dsp/ - displacement map /half/ - half space /hf/ - height field (deprecated) /pipe/ /raw/ - arbitrary polyhedron (right angle wedge) /tor/ - torus /vol/ - voxels Cuboid The rpp (rectangular parallelepiped) primitive to is used to create a cuboid using an area defined by the parameters xmin,xmax,ymin,ymax,zmin,zmax. # Insert a 2 x 3 x 4 cuboid named cuboid1.s into the database in cuboid1.s rpp 0 2 0 3 0 4 Sphere # Insert a sphere of radius 3 named ball.s into the database in ball.s sph 0 0 0 3 Cylinder
