Melemo ea motheo ea 3D: mokhoa oa ho etsa kosahedron ho tloha pampiri

E 'ngoe ea litaelo tse ratoang haholo ho origami ke 3D modeling. Ho etsa litšoantšo tse ngata ha ho hlokomele feela bana, empa le ba baholo. Haeba u se u ntse u tseba mekhoa le mekhoa e bonolo ka ho fetisisa 'me u ithutile ho etsa bonyane k'harasepe ea pampiri, u ka fetela mefuteng e rarahaneng haholoanyane. Ho molemo ho etsa ts'ebetso ea ho thoe "Platonic solids". Ho na le tse hlano feela tsa tsona: tetrahedrone, icosahedron, hexahedron, dodecahedron le octahedron. Lintlha kaofela li na le polyhedra e tloaelehileng, e itšetlehile ka lintlha tse bonolo ka ho fetisisa tsa li -geometric. Kajeno o tla ithuta mokhoa oa ho etsa kosahedron ho tloha pampiri.

Lethathamo la thepa le lisebelisoa

• Letlapa le le leng la lik'haboleta tse mebala-bala (mofuta o khethiloeng ke 220 g / m ² ).
• Lisekere tse bohale kapa thipa ea baruti.
• Pente e bonolo e nang le bothata ba HB.
• 'Musi e telele oa lepolanka (e seng ka tlaase ho 20 cm).
• Eraser.
• Motsoako oa PVA o khomarelang kapa pentšele.

1. Kaha ho ke ke ha khoneha ho etsa kosahedron ho tloha pampiri ntle le ho hlahlojoa, u lokela ho e fumana le ho e hatisa letlapeng kapa ho e taka ka letsoho. Tempele e na le likhalala tse 20 tsa equilateral tse kopantsoeng ka tatellano e khethehileng. Libakeng tse sa lefelloeng, ho hlokahala hore u fane ka indents e nyenyane bakeng sa ho khomarela.
2. O ka qala ho itšeha. Haeba u sebelisa thipa, etsa bonnete ba hore u sebetsa ka matheba a rabara bakeng sa mokhoa oa ho etsa liaparo, e le hore u se ke oa senya mapolanka a holim'a tafole.
3. Haeba u batla ho qoba lik'hamphani tse mpe nakong ea kopano, u lokela ho tsamaea litseleng tse khumamang ka ntho e bohale. Sena se tla etsa hore lifahleho li fapane haholoanyane.
4. Tsoela pele ho kopano. Etsa kopo ea sekhomaretsi ka liphaello mme u qale ho etsa sebopeho. Kaha ho thata haholo ho etsa kosahedron ho tloha pampiri feela, ho molemo ho kopa thuso ho motsoalle. Ho etsa bonnete ba hore methapo ha ea sisinyehe, e hloka ho tšoaroa 'me e kopane hammoho le likarolo tse ling. Mohlala o tla fumana boima ba ho qetela qetellong ea kopano. Ho bokella lifahleho tse peli tsa ho qetela ke ntho e thata ka ho fetisisa. Lichelete tsa bona li tlameha ho fetoha ka hare ho palo, 'me ka khatello e matla, sebopeho se ka' na sa felloa ke matla. E le hore e se ke ea senya ponahalo ea icosahedron, lehlakore la ho qetela le lokela ho kenngoa, ntle le ho kheloha mathōkong ho ea bofelong, 'me ka mor'a ho ba qobella ka hare.

Haeba u tseba hantle hore na u ka etsa mofuta oa icosahedron ho tsoa pampiri, u ka itloaetsa ho bokella mohlala o rarahaneng haholoanyane oa icosahedron e nang le truncated. Palo ena e na le lifahleho tse 32: li-pentagone tse 12 tsa equilater le li-hexagone tse 20 tse tloaelehileng. Ha o se o itokisitse mme o na le mebala e nepahetseng, e tšoana haholo le bolo ea maoto e entsoeng ka pampiri. Molao-motheo oa kopano o ts'oana, phapang e teng feela template. Ts'ebetso e kholo ea icosahedron e thata haholo ho haha, kahoo ho molemo ho e hatisa mochineng oa khatiso. Pampiri e lokela ho khethoa haholo, ho seng joalo setšoantšo se ke ke sa boloka sebopeho, 'me litšitiso li ka etsahala maemong a khatello.

Setšoantšo sa Origami le 3D ke tsela e ntle ea ho tlosa mantsiboea a botsoalle kapa a lelapa. Mesebetsi e joalo e etsa hore ho be le boitsebiso bo botle le thuso ho ntlafatsa monahano.
