Origami: Yuav ua li cas yuav ua rau ib tug dodecahedron ua los ntawm daim ntawv

Dodecahedron - ib tug polyhedron uas muaj 12 tib yam pentagons. Qhov no daim duab rau hauv lub hauv paus txheej khoom siv tes ua los ntawm desktop daim qhia hnub hli rau openwork tshem tawm Planning ahead is.

Yuav ua li cas yuav ua rau ib tug dodecahedron ua los ntawm daim ntawv?

Koj muaj peev xwm tsim koj tus kheej ib tug pentagon - nws yog yooj yim thiab guarantees siab precision duab. Yuav kom tsim ib tug tsis tu ncua pentagon yuav xav tau ib tug compass thiab ib tug nom. Kos ib lub voj voog ntawm cov kev kawm loj. Siv qhov twg voos kheej-kheej. Yuav kom ua tau lwm perpendicularly thereto voos kheej-kheej. Ces ib tug ntawm cov radii yog muab faib ua ob sib npaug zos qhov chaw. Txhua ib nrab yuav ib tug txawv voos kheej-kheej, ib tug me me lub vajvoog, uas yuav ua tau lub luag hauj lwm ntawm ib tug pab. Tom ntej no, txuas rau qhov chaw ntawm lub koom haum pab vajvoog mus rau qhov chaw nyob qhov twg cov yooj yim vajvoog voos kheej-kheej tshuam rau lwm yam (piv txwv li, nyob rau ntawm lub taw tes A). Cov uas ua kab yuav tshuam lub koom haum pab vajvoog ntawm ib tug taw tes - B. Qhov kev ncua deb AB yog ib feem kaum ntawm lub voj voog. Qhov ntawd yog qhov kev ncua deb ib compass mus kos tus cim rau hauv lub hauv paus vajvoog, thiab ces txuas cov ntsiab lus los ntawm cov kab ncaj nraim los ntawm ib tug - ib tug tsis tu ncua pentagon yog npaj txhij!

Muaj lwm txoj kev. Piv txwv li, ib tug pentagon yuav raug ua lub tsev siv ib tug protractor, tab sis tsis tau lees tias tus neeg ntawm nws. Feem ntau cov Lihais txoj kev - mus coj npaj txhij-ua tswvyim, sau nws, thiab rau qhov no, "tus qauv" yog twb tinkering ntawm txoj cai ntawv crafts. Tab sis qhov no txoj kev, Txawm hais tias yooj yim, yog tsis ib txwm tsim - vim hais tias tej zaum koj yuav tau ua ib dodecahedron ntawm ib tug loj. Koj muaj peev xwm ntug ib zaug xwb pentagon mus rau lub yam loj thiab sau nws tib leeg xwb, ces tsim ib daim duab nyob rau hauv daim duab hauv qab no.

Tab sis lub "qauv" - yog tseem tsis tau npaj txhij rau hack. Yuav ua li cas yuav ua rau ib tug dodecahedron ua los ntawm daim ntawv? Qhov no yuav tsum:

1. Ntawv haum ceev. Nws yuav tsum tsis txhob yuav ib yam nkaus thiab nyias los yog heev tuab - dua li 220 g / m², nws muaj ib tug ntom paperboard, uas yog muag nyob rau hauv poob lawm ntawm cov me nyuam. Txawm tias ua los ntawm tuab duab los qhia yog ua tau kom tsim peb-dimensional nuj nqis, koj tsuas yuav tau pre-txheej txheem tag nrho cov folds - snick los yog zoo laub, hais tias lawv yog cov zoo thiab evenly bent.

2. txiab, mem hluav, kua nplaum, ib tug knitting koob los yog ib tug riam sau

Lub tswv yim rau kev ua ib tug dodecahedron

Ntawv ntawm lub quav yog ntshaw kom ib nyuag thawb lub koob, lub blunt sab ntawm sau riam los yog ib yam dab tsi ntse, tiam sis tsis txiav. Zoo huv si folds tiaj - ib nrab ntawm cov kev kawm tau zoo.

Yog hais tias cov kua nplaum yog tsis nyob rau hauv tes, lub dodecahedron yuav sau, raws li ib tug constructor, ua ib qho kev incision raws crease thiab ces cias inserting ib sab mus rau hauv ib leeg.

Yog hais tias koj sau ib tug dodecahedron nyob rau hauv modular txheej txheem (cov lus qhia hauv qab no), ces cov pob qij txha ntshaw prokleivat los yog khawb rau kev txhim kho, txij li thaum cov qauv yuav ruaj khov tsuas yog tom qab kho tas los module.

Dodecahedron nyob rau hauv origami txheej txheem

Module origami - ib qho zoo heev lub hauv paus rau lub dodecahedron. Yuav ua li cas yuav ua rau ib tug dodecahedron los ntawm ib daim ntawv nyob rau hauv ib tug modular txheej txheem? 30 yuav tsum tau ib lub los yog square los xij ntawm daim ntawv. Txhua yam ntawm tus leaflets daim ntau quav tso nyob rau hauv ib nrab, ces txhua ib nrab khoov nyob rau hauv kev coj rov qab - nws yuav "accordion" nyob rau hauv plaub ntxiv. Tej zaum, yog hais tias tus ntawv no tsis yog square, ua ib tug "harmonica" nyob rau hauv peb ntxiv. Raws li ib tug tshwm sim uas koj muaj nyob rau hauv lub ob txhais tes ntawm ib tug nqaim sawb ntawm promougolnaya. Ces, rau txhua sab ntawm lub duab plaub raws nqaim sab ntawm lub flexing cheeb tsam. Fab yog tsim nyob rau hauv ib tug kev taw qhia - lub neej yav tom ntej ntawm fastening yuav tsum tau refueled nyob rau hauv lub "harmonica". Ces khoov lub module inward sis diagonally los ntawm lub ces kaum ntawm lub me me sab. Yog li, ib tug module origami dodecahedron - ib tug peb-dimensional, nws muaj xws li ob npoo thiab cov ces kaum ntawm daim duab lub neej yav tom ntej. Thaum tag nrho cov modules yog npaj txhij, koj muaj peev xwm pib los ua ke.

Cov los ua ke pib nrog ib tug ib node uas koj xav kom muab peb modules. Tus naj npawb hauv qab no yog ib tug xiav, liab thiab daj origami ins. Los ua ke kos duab yog haum yooj yim, thiab nrog xws li cov nuj nqis yuav yooj yim heev lis txawm tus novice.

Yuav ua li cas crafts yuav ua rau lub hauv paus ntawm ib tug dodecahedron?

Txhua sab ntawm lub dodecahedron ua los ntawm daim ntawv - ib tug ca pentagon, uas nyob rau hauv nws tus kheej yuav ua tau lub hauv paus rau ntau yam thiab bizarre cov ntaub ntawv. Piv txwv li, nyob rau hauv cov kev yees duab hauv qab no pentagon hloov los ntawm ib tug tsib-taw lub hnub qub. Cov tav nyob rau hauv no daim duab no tsis muaj, txawm tias nws yog lam xav. Yuav ua li cas yuav ua rau ib tug dodecahedron ua los ntawm daim ntawv nyob rau hauv tus duab ntawm ib lub hnub qub? Hloov nyob rau hauv lub cheb, qhia saum toj no, txhua pentagon yuav tsum tau tsib-taw lub daim duab thiab txuas lawv tsis nyob rau hauv lub tav thiab nyob rau hauv saum.

Nyob rau hauv no yees duab yog hais stellated dodecahedron. Hauv plawv ntawm txhua tus "beam" yog tseem tib pentagon.

tej volumetric zoo tej zaum yuav tsim tsis muaj tus pentagonal pyramids.

Nyob rau hauv cov kev yees duab hauv qab no raws li pentagons ua ntau origami circuits, uas yog xav nyob rau hauv cov txheej txheem no muaj nyob rau hauv cov ntawv nyeem.

Nyob rau hauv txhua rooj plaub, txoj kev loj hlob ntawm txawm nyuaj los ua ke tswvyim dodecahedron twb muab cib fim rau creativity thiab nrhiav tau lawv tus kheej kev xaiv.
