Scan polyhedron nokuda kwokuva. Scan stellate polyhedron

A zvinhu zvakawanda zvinonakidza zvaunogona kuwana, nokuti pacharo muzvinhu nesayenzi, izvo, sokuti, hazvizombofi kupinda batsira senguva dzose muupenyu nevakariri murume ari mumugwagwa. Somuenzaniso, geometry izvo vakawanda vakakanganwa, chete kuburikidza magedhi chikoro. Asi vasinganzwisisiki sainzi yausingazivi inonakidza chaizvo, kana atarisana navo kunyatsotevera. Kuti geometric polyhedron Ongororo - zvachose zvisingakoshi chinhu muupenyu hwezuva nezuva - zvinogona kutanga inonakidza okugadzira zvinhu, kukwanisa kubata vose vana nevakuru.

Beautiful geometry

Shongedza mukati imba, ndinosika maoko avo kujairika, Stylish zvinhu - icho chinonakidza basa. Ita vako kubva kuvakwa bepa siyana polyhedra - zvinoreva kuti asike zvinhu rakasiyana zvinogona kuva dandadzo nokuda zuva kana maviri, asi anogona kuva anogadzira nechomukati zvemaoresa. Uyezve, pamwe kukura zvigadzirwa inokwanisa spatial Modelling yamarudzi ose ezvinhu, zvaibvira kusika munhu dzemhando yepamusoro uye akararama 3D-yokutevedzera. Kune mhizha vanoshandisa prostroeniya kuchavazvuzvurudzira pasi mitemo geometry akaita mapepa yokutevedzera zvemhuka uye zvinhu zvakasiyana-siyana. Asi ichi ndicho nani kunzwisisa akarongeka uye mufanidzo zvisikwa. развертка многогранника. Tanga kushanda kwenzira yakafanana achaita tarisei polyhedron.

zviso zvakasiyana - siyana siyana

Polyhedra - rinokosha idenderedzwa geometry. Vane nyore - somuenzaniso cubes, izvo vana kutamba kubva vaduku - uye pane kwazvo kunzwisisa. достаточно сложной областью конструирования и творчества: нужно не только знать основы черчения, геометрические особенности пространства, но и иметь пространственное воображение, позволяющее оценить правильность решения еще на стадии проектирования. Prostroenie kushanda pakuvheneka polyhedra nokuda kwokuva anoonekwa kuva chaizvo kunzwisisa nharaunda zvakagadzirwa zvinhu uye: mumwe havafaniri chete kuziva zvinokosha kudhirowa, geometric zvechadenga nzvimbo, asi vane spatial fungidziro, izvo anobvumira kuti vaongorore yakarurama rokusarudza nemagadzirirwo rwakazara. Asi munhu angagona kuita fungidziro. Kuti kushanda pakuvheneka polyhedra pabepa, kwete zvakakwana chete kufungidzira sei pakupedzisira vanofanira kutarira akafanana basa. Zvinofanira kunge achikwanisa nemazvo kuverenga, kuvaka uye nounyanzvi kuzochera.

The polyhedron rokutanga - kuutio

Ungangove, munhu wose ari kupinda chikoro, kunyange puraimari makirasi mhiri basa basa, mugumisiro iyo aifanira kuva pepa kuutio. развертки многогранника куба на плотной бумаге со специальными кармашками, предназначенными для склеивания граней модели в единое целое. Kazhinji, mudzidzisi vakaparadzira preform - kushanda pakuvheneka kuutio polyhedron achirovera bepa chaizvo muhomwe, akaronga kuti Muitiro unobatanidza womuenzaniso anotarisana pamwe chete. basa iri kupurayimari vadzidzi vaigona kuva vanodada, rubatsiro bepa, chigero, guruu, uye zvavaiita kuti anonakidza kwebhokisi nokuti vane - a-dimensional matatu kuutio.

kunakidza vatarisana

Zvinoshamisa, yakawanda ruzivo pamusoro nyika havasi kufarira chikoro, asi chete kana zvichibvira kuwana maari chinhu rinonakidza kuti anogona kupa chinhu chitsva uye kujairika mune yaizivikanwa upenyu. Havasi vanhu vakuru vakawanda yeuka kuti imwe polyhedra vanokamurwa kuva kuwanda kwemarudzi uye subspecies. Somuenzaniso, pane anonzi Platonic nezvishoma - convex polyhedra, iine chete dzose polygons. miviri kwakadaro shanu chete: kuti tetrahedron, octahedron, hexahedron (kuutio), icosahedron, dodecahedron. Dzinomirira munhu convex chimiro pasina in. Star-zvakaumbwa polyhedra anoumbwa dzinokosha zvitarisiko aya configurations siyana. развертка многогранника простого позволяет нарисовать, вернее начерить, а затем и склеить из бумаги звездчатый многогранник. Saka, zviri nyore Scan ane polyhedron kunoita kuti tiswedere nani nacherit, uye ipapo micheto yekapepa katsva aka bepa stellate polyhedron.

Kugara uye kutadza stellate polyhedra

VaGumbo Platonic nezvishoma pamwe imwe kuti, unogona kuvaka yakawanda nyeredzi mnogorannikov - akanaka, yakaoma, multi-chikamu. Asi vachanzi "mugari stellate polyhedra". Right stellate polyhedra ndivo chete mana duku stellated dodecahedron, mukuru stellated dodecahedron, hombe dodecahedron uye icosahedron kukuru. Kushanda pakuvheneka polyhedra nokuti chokuedza haangazorori nyore vanodhirowa. Ivo, kufanana nhamba zvichaparadzwa rinoumbwa zvakawanda zvinoriumba. Somuenzaniso, vaduku stellated dodecahedron inovakwa kubva 12 pentagonal isosceles Pyramid rinoumbwa mhando dzose dodecahedron. Kureva kuti kutanga achafanira kuwana uye micheto yekapepa katsva aka 12 akafanana zvidimbu dzose mapiramidhi anoumbwa 5 zvakaenzana mativi. Uye chete ipapo munhu anogona akapeta nyeredzi serin'i polyhedron. Atarise zviduku stellate dodekaera - yakaoma uye kwakaoma zvisingaiti basa. Prostroen kwairi, unofanira kukwanisa kukodzera pamusoro chete ndege chokuita nevamwe 13 Scans siyana geometric vhoriyamu miviri neimwe.

Beauty muumwe

Vose voluminous muviri kuvakwa maererano nemitemo geometry, vachatarira zvinonakidza, kusanganisira nyeredzi serin'i polyhedron. Scan mumwe chinhu muviri chakadai zvinofanira kuitwa sezvo kunyatsotevera sezvinobvira. Uye kunyange nyore volumetric polyhedra, sezvo Platonic tetrahedron - kunoshamisa runako kubvumirana zvakasikwa uye basa kwevanhu mudzidziso pepa womuenzaniso. Pano, somuenzaniso, kupfuura ichiita mabasa akawanda ari Platonic convex polyhedra - dodecahedron. развертки правильных многогранников для склеивания, нужно приложить максимум аккуратности и внимательности. Izvi geometric mufananidzo 12 zvachose kufanana zviso, 30 micheto uye 12 kuita kushanda pakuvheneka vershin.Chtoby dzose polyhedra nokuda kwokuva, zvinokosha richiva kunonyanyisa kunyatsotarisirwa. Zvino hombe kukura nechipi, nani kuva nezviyero zvose.

How kuvaka yako Ongororo?

Zvichida, kuwedzera kune chokuedza mumwe polyhedron - kunyange stellate, kunyange Plato - kunyange kunakidza kuvaka remangwana mhando atarise zvavo, dzinoongorora chipo kwavo kudhirowa, magadzirirwo spatial voobzheniyu. Simple miviri platonovstkie akaumbwa nyore polygons, izvo mune chimwe chimiro akafanana nomumwe. Somuenzaniso, imwe tetrahedron - munhu isosceles zvokuridza matatu. Tisati prostroen Ongororo, unofanira kufunga kuti peta sandara polygons nemumwe kuwana polyhedron. Triangles zvinogona chokuita mumwe ari mbabvu nokuswedera pedyo nepedyo. Nokuti Muitiro unobatanidza polyhedra kutsvaira redunhu anofanira inopiwa chaizvo muhomwe kana ichibhabhamisa kuti zvichaita chokubatanidza zvose kumativi ive rose. Tetrahedron - chete dimikira zviso zvina. Octahedron rinogona achimiririrwa miviri tetrahedron, ane masere Garnier - isosceles zvokuridza. Hexahedron akadana yaizivikanwa zvose kubva pauduku kuutio. Icosahedron ndiyo mukomboni 20 isosceles zvakarurama zvokuridza ari convex polyhedron. Dodecahedron - a volumetric dimikira 12 kunobatanidza, chimwe nechimwe chiri dzose nePentagon.

Avake polyhedron developable uye guruu bepa muenzaniso nayo - a kuputsika nyaya. Scan Chokwadi, unogona kutora akagadzirira akagadzirwa. Uye zvinokwanisika, nokushandisa uslily, nekuivaka pachako. Asi kuti wenguva-dimensional matatu polyhedron womuenzaniso, unofanira kutora nayo. A polyhedron ari zvakanakisisa kubva gobvu pepa munoiswa chimiro chayo zvakanaka uye asingauyi avhiringidze kubva guruu. mitsetse All kuti hwakakungwa, zvakanakisisa kwerubwinyo rwakagara rwuripo kusunda, kushandisa Somuenzaniso, nepishuschuyu ballpoint chinyoreso kana seri banga chipasa. nuance Izvi zvichabatsira huripo womuenzaniso zvakarurama, achiita zvaidiwa kukura uye achitungamirirwa mbabvu.

Kana kuti siyana polyhedra mavara bepa, mienzaniso iyi inogona kushandiswa decoration zvinhu kuti vashongedze chivakwa - mukamuri chevana, hofisi, yokutandarira. Panzira, kuti polyhedra anganzi rakasiyana kuwana decorators. Modern zvinhu achitirega kwakavakirwa geometric zvitarisiko kusika yepakutanga menyika.
