Line 8: ==Construction== [[File:Dodecahedron flat.svg\|thumb\|A net for the regular [[dodecahedron]]]] Construction begins by choosing a ''size'' of the model, either the ''length'' of its edges or the ''height'' of the model. The size will dictate the ''material'', the ''adhesive'' for edges, the ''construction time'' and the ''method of construction''. Line 16 ⟶ 17: An alternative way for [[polyhedral compound]] models is to use a different colour for each polyhedron component. Net templates are then made. One way is to copy templates from a polyhedron-making book, such as [[Magnus Wenninger]]'s ''[[List of Wenninger polyhedron models\|Polyhedron Models]]'', 1974 ({{ISBN \|0-521-09859-9}}). A second way is drawing faces on paper or with [[computer-aided design]] software and then drawing on them the polyhedron's [[Edge (geometry)\|edge]]s. The exposed nets of the faces are then traced or printed on template material. A third way is using the software named ''[[Stella (software)\|Stella]]'' to print nets. A model, particularly a large one, may require another polyhedron as its inner structure or as a construction mold. A suitable inner structure prevents the model from collapsing from age or stress. Line 25 ⟶ 26: ==Interactive computer models== Recent [[computer graphics]] technologies allow people to rotate 3D polyhedron models on a computer video screen in all three dimensions. Recent technologies even provide shadows and [[texture (computer graphics)\|textures]] for a more realistic effect. ==See also== [[Polyhedron]] [[List of Wenninger polyhedron models]] ==External links== [http://www.software3d.com/Stella.php Stella: Polyhedron Navigator]: Software to explore virtual polyhedra and print their nets to enable physical construction [https://web.archive.org/web/20050403235101/http://ibiblio.org/e-notes/3Dapp/Convex.htm Interactive 3D polyhedra in Java]▼ [http://www.software3d.com/MyModels.php Paper models of many polyhedra] [http://www.korthalsaltes.com/ Paper Models of Polyhedra] Many links [http://www.polyedergarten.de/ Paper Models of Uniform (and other) Polyhedra] ▲[http://ibiblio.org/e-notes/3Dapp/Convex.htm Interactive 3D polyhedra in Java] [http://www.flickr.com/photos/pascalin/sets/72157594234292561/ Origami Polyhedra]: Photos of models made with modular origami [http://bulatov.org/polyhedra/wooden/ Wooden Polyhedra Models] [http://www.georgehart.com/virtual-polyhedra/vp.html George Hart's extensive encyclopedia of polyhedra] [http://www.georgehart.com/pavilion.html George Hart's Pavilion of Polyhedreality] [http://polyhedra.org Online rotatable polyhedron models] [http://woodenpolyhedra.web.fc2.com/woodenpolyhedra30.html WOODEN POLYHEDRA 30] [[Category:Recreational mathematics]]
