Ukuze ukunceda iingcibi abaselula ukuba ukwenza njani iphepha ukusuka tetrahedron

Ukuba ngesiquphe ubunokunikwa umsebenzi kwi isifundo geometry, okanye ngokwawo umnqweno ukuhlaziya iimpawu memory yamanani-ntathu, ngoko umele ngokuqinisekileyo ufunde indlela yokwenza iphepha ukusuka tetrahedron, kwaye qiniseka ngokusebenzisa la macebiso ayo. Ngapha koko, eli nani ngenxa elula yayo yenye imifuziselo ezisisiseko yokubumba-ntathu.

Igama elithi "tetrahedron" nga kuguqulelwa ngokusuka kwisiGrike njenge "tetrahedron". Eneneni, into ekuthethwa inobuso obune yonxantathu kunye eziphezulu ezine kunye nokuphela kwegqabi ezintandathu. Kukho zenyathi emininzi yeli nani, kodwa asiyi baxoxa zonke iinketho kunokwenzeka. Kweli nqaku uya kufunda iindlela zokwenza njani iphepha tetrahedron. Oku kuya kuba tetrahedron rhoqo, bonke ubuso oonxantathu alinganayo.

Kuba umsebenzi akukho mfuneko yokuba uye kungena izibalo ezintsonkothileyo zemathematika musa ukuba ukubala nawuphi na umthamo we tetrahedron, okanye indawo, okanye ubude. Inye kuphela into eyimfuneko, - noxwebhu lwephepha, ipensile, izikere neglu, kwaye SRES kwaye ukwenza iphepha kuphela.

Ekubeni iphepha ukwenza tetrahedron, ngazo zonke izinto eziyimfuneko? Kukho iindlela ezininzi. Wokuqala kwaye ethandwa ukhetho: wonqanyulwa, oonxantathu ezine ezahlukeneyo kunye ekuthiwa "ezinamagqabi", ezithi ke ngoko unamathela kunye. U nga tshinela unxantathu alinganayo ngokwazo okanye asebenzise itemplates esele zenziwe. Izinto eziluncedo yale ndlela ziquka ithuba lokuba wabaza multi-bala, ngokuthatha iphepha imibala kunye shades ezahlukeneyo. Eli nqaku liza kunika nobumhlophe kunye ujongo ezinomdla kakhulu.

Indlela yesibini akumi ubuhlobo ndahlukane oonxantathu, kwaye sele idityaniswe nezinye (ebizwa ngokuba yi-scanning tetrahedron) ngamnye. Kulo mzekelo, naye, kusenokubakho iinketho eziliqela, ezizezi ngenxa kuncanyatheliswe le ezinamagqabi abe zonke elintlangothi ezivulekileyo, okanye abathile kuphela, abo ubuncinane ukuba kufanelekile ekhuselekileyo.

Ke ekugqibeleni, eyesithathu indlela ngokujonga indlela yokwenza iphepha ukusuka tetrahedron, siyakwazi ukubona ukuba akukho sidingo sokuba naziphi yokuncamathelisa, ngenxa enye ngumfuziselo ibandla lo mzobo zejometri yi origami yemodyuli. Nantsi iphiramidi umngxuma kunokwenziwa ngokusebenzisa le ndlela, kunye isitokhwe ezaneleyo iphepha, ukunyamezela nomonde. Ngokwesiqhelo, akukho entsonkothileyo kakhulu, kodwa kunokuba nzima umsebenzi, kwaye kweli nqaku asiyi kubanika imiyalelo eneenkcukacha. Ukuba unomdla kule nkcukacha, uya kuyifumana imithombo malinikelwe kulo art Japanese. Kwaye, ukuba uyayekelela inkathazo ukufumana imiyalelo kule yobugcisa, kungekudala uya ngokulula ziba isakhiwo a ezintsonkothileyo.

Nganye ngasentla zinezibonelelo yayo phezu kwabanye, yaye bonke befanelekile nesebenzayo. Kwaye ukhethe indlela ukufanele kufuneka sisekelwe ekufumanekeni ixesha nomonde, kwakunye nenjongo imodeli kwixesha elizayo tetrahedron.
