Polytope play made easy

Human: Polygons and polyhedrons are the most powerful shapes available in OpenSCAD. However, it can sometimes be a challenge to construct them correctly. Consider this library to help you construct and work with your Polytopes. Tools module polytope_number (c, f, e, vi=true, fi=true, ei=true, sp=false, ts, th, to, tr=0) Label the vertices, paths, and edges of a polytope. module polytope_frame (c, f, e, vi=true, fi=true, ei=true, fc=-1, vc=-1, ec=-1) Draw a polyhedron with specified colors for faces, vertices, and edges. module polytope_number (c, f, e, sp=true) Label the number of each face type on a polyhedron. Framing include <polyframe.scad>; tc = dtc_polyhedra_johnson; tr = dtr_polyhedra_johnson; id = "metagyrate_diminished_rhombicosidodecahedron"; c = get_table_v(tr, tc, id, "c"); f = get_table_v(tr, tc, id, "f"); v = coordinates_csc(c, 100); polytope_frame(v, f); Framing include <polyframe.scad>; tc = dtc_polyhedra_cupolas; tr = dtr_polyhedra_cupolas; id = "pentagonal_cupola"; c = get_table_v(tr, tc, id, "c"); f = get_table_v(tr, tc, id, "f"); v1 = coordinates_csc(c, 100); v2 = coordinates_csc(c, 100, true); grid_repeat(2, 225, center=true) { polytope_frame(v1, f) {circle(r=4); color("grey") sphere(r=6);} polytope_frame(v2, f) {circle(r=4); color("grey") sphere(r=6);} } Shapes on edge, vertex, face include <polyframe.scad>; tc = dtc_polyhedra_archimedean; tr = dtr_polyhedra_archimedean; id = "truncated_cuboctahedron"; c = get_table_v(tr, tc, id, "c"); f = get_table_v(tr, tc, id, "f"); v = coordinates_csc(c, 100); polytope_frame(v, f, fi="even") { circle(r=2); color("grey") sphere(r=4); color("red") star3d(20); } polytope_frame(v, f, fi="odd", fc=0, vc=-1, ec=-1) color("blue") star3d(20); polyhedron(v, f); omdl This design uses omdl. To render the design, this library must be available. More information is available in omdl on thingiverse. To install omdl open a BASH shell and type: $ mkdir tmp && cd tmp $ wget https://git.io/setup-omdl.bash $ chmod +x setup-omdl.bash $ ./setup-omdl.bash --branch v0.6.1 --yes --install
