Iyini le drill eqeqesha ngayo

I-ellipsis iyidayimane ebonakala e-angle, futhi umthetho olungisa wonke umuntu ukuthi: ukuthi ibukeka kanjani ijikeleze kuxhomekeka ngokuphelele ukuthi ifinyelela kuphi ukusuka ehlathini lekhanda lakho. Linganisa ngekhanda lakho, i-ellipsis iyilayini eqondile. I-flat esitezi ngezansi kwakho, ifinyelela phezulu kwedayimane futhi. Konke okuphakathi kuyi-ellipsis, futhi i-degree yayo iyimingwane mayelana nokuthi umbukeli uhlala khona.

Umthetho wesithathu usebenza ngemishini ngaphezu kokungaqondi. I-ellipsis enhle idwetshwa ngokushesha, ihamba ijikeleze izikhathi eziningi emjikelezweni owodwa oqhubekayo, bese ugcina i-pass enhle. Idwetshwa ngokucophelela iphuma i-lumpy ngakwesobunxele ngaso sonke isikhathi, ngoba isandla asikwazi ukuvikela i-curve elula ngejubane eliphansi - iqiniso elifanayo lemvelo eliyenza ama-line ahamba phambili ahamba kancane.

Le yi-drill ephakeme kakhulu yokudlulisa kulesi sayithi. Ama-mugs, amamoto, ama-tins, amabhodlela, ama-plates, ama-hats, amazinyo kanye ne-wheel ngayinye ozoba nayo idinga izinkinga ezifanayo eziyizinkulungwane ezahlukene, ngakho-ke ihora elichitha lapha libuyisela emuva isigaba esigcwele sesihloko ngaphezu kwesinye.

Indlela yokwenza

1. Qalisa ukhethe i-axis ende bese uyidweba njengelayini eqondile ekhanyayo. I-ellipsis ifana ne-axis, futhi ngaphandle kokudweba awukwazi ukubona uma i-axis yakho ayinjalo.
2. Qalisa ucabange ukuthi ijikeleze kanjani ngaphambi kokuqala - lokhu kuyizinga, futhi kuvela kulokho okude isakhiwo sisuka esigabeni semehlo akho.
3. Hlela bese uphinde u
4. Chofoza phansi bese uhamba ujikeleze izikhathi ezintathu noma ezine ngaphandle kokuyeka. Ungakhuphuli phakathi kwezinqumo.
5. Misa uma kuqhubeka kuhlanzekile. Izinkulungwane ezingu-6 zibi kunazo zonke, ngoba ngenkulungwane yesi-6 ulungisa ngaphandle kokudweba.
6. Khangela ngokumelene ne-axis. Uma inhlamvu eyodwa ikhulu, i-ellipsis yonke i-tipped ngaphandle kokubukeka kabi - zoba kabusha ngaphandle kokuveza i-side ekhulu.

Ubukeka kanjani okuhle

I-ellipsis engcono ifana ngokufana ngazo zonke izixhumanisi zayo, ayinazinhlamvu eziqinile futhi ayinazinhlangothi, futhi yenziwe ngemikhawulo emibini noma emithathu edlulayo elandela indlela efanayo. Enye ebi inengxenye eqinile, inhlangothi ezibonakalayo lapho ama-arcs amabili ehlangana khona, noma iziphelo ezingavalanga.

Isimo sesandla sokudla siyi-elips ehamba kancane ejwayelekile: incazelo eqondile engezansi, i-corner lapho umbhali eshintsha khona indlela, nethuba lapho amaphethini amabili engakwazi ukuhlangabezana.

Yini esiyilinganisela, nokuthi yini ekushoyo inani

Le drill ithola indawo - noma ngabe i-mark iwela lapho ihlolwe khona. Uma i-ellipsis ikhona, lokhu kusho izinto ezintathu: ukuthi ibanga linjani ubuso besimo sakho sihlala kusuka ku-target engxenyeni engcono kakhulu, noma ngabe ama-halfs amabili afana ngaphesheya kwe-axis ende, noma ngabe izimo zivumelana ngazo.

Ukugqwala kubhekwa ngokuhlukile njengelayini yokwethemba, ngakho-ke i-ellipsis ephazamisayo endaweni efanele futhi ephazamisayo endaweni engekho ilahlekelwa ngokuhlukile futhi ithola incazelo ehlukile. Lo mhlukaniso yisizathu sokuthi i-elipsis encane yodweba izoba yikho.

Uma inhlanganiso ikhiqiza izimo ezivaliwe ezincane kakhulu zokuqhathaniswa, akukho okuthunyelwe kulo mhlangano. Sizobonisa isikhala kunenani esingalikholwa.

Izifundo ezisiza lesi siqukathi

Noma yini eyisilinda, noma yini enendawo yokujikeleza, kanye nemehlo ongawadweba. Lawa amathuluzi lapho i-ellipsis iyisisulu sangempela ngaphezu kwengxenye encane.

Indlela yokudweba ibhodlela - ama-ellipsis amabili adinga ukuvumelana · Indlela yokudweba i-ice cream cone - ama-circles ahlanganisana · Indlela yokudweba imehlo - i-iris iyi-ellipsis, hhayi i-circle · Indlela yokudweba i-apple - i-sphere engalingani · Indlela yokudweba ikati - ama-circles amabili alinganayo ngaphansi kwesikhumba · Indlela yokudweba isithombe - ikhanda liyibhola

lapho kuvame ukuphoqelela khona

Uzozoza ngokucophelela. Lokhu kwenza indawo ehlanzekile engxenyeni eyodwa ngaphandle kokulahlekelwa, futhi akukho lutho oluzosusa - isivinini kuphela esikwenzayo.

Ukwakha i-arc emibili. I-arc emibili emibili exhunywe inikeza ama-corners amane, futhi imehlo lithola ngalinye lazo.

Ukudweba kuphela inhlamvu ebonakalayo. Ku-mug noma i-tin, zoba i-ellipsis ephelele kufaka phakathi inhlamvu efihlakele emuva kwento, bese ukhetha ukuthi yini ongayicisha. Ukudweba kuphela i-arc engaphambili kunikeza i-rim engeke ivale.

Ukungaqapheli ibanga. Uma iphezulu yesilinda ijikeleza kakhulu kunesisekelo sayo, into ihamba phambili kuwe, futhi lokho akuyona into ofuna ukuyidweba.

Isikhathi sesiqephu

• 60 second warm-up Ukushisa, hhayi inhlanganiso. Imisebenzi yayo ukuthatha i-line yokuqala ebi yosuku ngaphandle kwendlela lapho ayibalulekile khona - yenza ngokushesha ngaphambi kokufunda.
• 5 minute session Inhlanganiso engokoqobo, kanye nephutha. Ide ngokwanele ukuthi ukulungisa kuqale kwenzeke ngaphakathi kwengqungquthela endaweni yokungaphakathi kwabo.
