Indlela yokudweba isilinda epensela ngesithunzi esiteji? Imiyalo nezinyathelo ezinyathelo ngezinyathelo

Abanye abantu bacabanga ukuthi kulula kakhulu ukudweba izibalo ze-geometric , kodwa lokhu akukwenzeka neze. Ukuze ubonise ivolumu nesithunzi, udinga ikhono nokunemba emsebenzini. Cabanga indlela yokudweba isilinda nge pencil.

Okokuqala

Kunezinketho eziningi zokudweba ngepensela, sizohlaziya omunye wabo ngesinyathelo ngesinyathelo. Ukuze usebenze uzodinga ipensela, mhlawumbe ukunciphisa okuphakathi, i-eraser kanye neshidi lephepha elimhlophe, ungathatha ifomethi ye-A4.

Inkambo yomsebenzi:

1. Dweba imigqa emibili efana. Kusukela ngenhla nangaphansi, xhuma izingxenye nge-ovals. Njengoba lokhu kuyisifundo sokudweba, ungasebenzisi noma yibaphi ababusi, zama ukubeka isandla sakho ngokushesha ukuze wenze kube lula ukudweba izinto ezahlukene esikhathini esizayo.
2. Yenza imigqa emibili ehamba phambili e-oval ephezulu, futhi kusukela phakathi, udwebe umugqa phansi.
3. Ukusuka ngezansi, udwebe imigqa emibili.
4. Zungeza uhlaka ngokucacile bese uqhubekele ekwenzeni isithunzi.
5. Khetha uhlangothi olufanele lomthunzi omnyama, ngakwesokunxele u-cylinder uzohlala emhlophe. Sebenzisa isithunzi ngokucophelela, shading ipensela. Umthunzi kufanele ushintshwe kahle kakhulu.
6. Dweba isithunzi esivela ku-cylinder. Kusukela ngakwesokudla sisebumnyama, ngakho-ke siyayimelela ngaphambili.
7. Ubude obuqondile abukho, ngoba ngezikhathi ezahlukene zosuku ubude besithunzi kusuka ezintweni abufani.
8. Kulesi simo, sithatha cishe ingxenye yesithathu yokuphakama kwesilinda. Dweba izingxenye ezimbili ezifanayo ze-diagonal bese ujoyina ama-vertices.
9. Paint isithunzi.

Umsebenzi usulungile. Lokhu kungenye yezinketho ezilula, ngoba asizange sisebenzise amathemba futhi siboniswe kuphela isilinda.

Ukhetho lwesibili

Kulesi sigaba esiyinhloko sizocabangela indlela yokudweba isilinda ngepensela ezingeni eliphezulu lochwepheshe, ngakho-ke uma ungaqiniseki ngamakhono akho, kungcono ukungathathi umsebenzi. Futhi futhi le nqubo yehluzo ayifanele izingane ezincane.

Umsebenzi uzodinga:

• Iphepha, ne-Wabasaqalayo kungcono ukuthenga ukuhlunga okukhethekile, okungcono ukudweba;
• Amapensela amaningana anezinselele ezahlukene zobunzima;
• I-Eraser;
• Namathela ukugaya umthunzi (ungakwazi nje ukugoqa leliphepha bese ungena).

Iseluleko ngaphambi kokuqala kokusungula: ukwakha umdwebo ngemivimbo enzima, njengoba kulula ukuwasula kamuva.

Siphendukela emsebenzini ngokwawo, indlela yokudweba isilinda ezinyathelweni:

1. Maka uphawu. Lokhu kuyadingeka ukucacisa kahle indawo yendawo.
2. Senza umkhawulo. Ngalokhu, dweba imigqa emibili ngesandla, ucindezela kalula ipensela. Khona-ke ezimbili ezizungezile - ezivela phezulu nangaphansi, ukuxhuma umugqa.
3. Ngokulandelayo sithola i-ellipses (kusukela ngezansi nangaphezulu) - lokhu kuyisisekelo se-cylinder. Ukuze ubenze ukuma okulungile, kusukela enkabeni yomugqa ophezulu nesezansi, phawula amaphuzu amabili ebangeni elifanayo kuzo zombili izinkomba ebangeni elifanayo, bese udweba isibalo.
4. Ake siqhubekele ukuxhuma. Ake sithi umthombo wokukhanya utholakala phezulu ngakwesokudla. Futhi, kusukela kulokhu, sizokhipha izindawo eziqhakazile nezimnyama kakhulu.
5. Uhlangothi olumnyama luyoba phambili, kancane ngakwesokunxele sendawo. Manje siphenduka ekuthungeni, kuyisifiso sokuthi imivimbo iphinda isakhiwo sezinto.
6. Kusele ukudweba isithunzi esivinini, senze sibe sincane futhi sibe ngesimo se-cone esenzelwe isilinda.

Umsebenzi usulungile. Ukufihla ukukhanya kwe-hatching, sithatha ukusula induku noma iphepha bese sidlula ngokuhamba kancane ezinkampeni kuze kube yilapho sifinyelela umphumela oyifunayo.

Kungcono ukukhulisa amakhono akho ngokudweba into yangempela, ngakho-ke kunengqondo ukuthatha into yesikhala. Ngomumo wesilinda, kunezinto eziningi eziseduze nawe, isibonelo, ingilazi.

Izilingi eziningi

Manje cabanga indlela yokudweba isilinda nge ipensela ngesithunzi, uma sifuna ukuveza izinto eziningana ngesikhathi esisodwa.

Isiteji sesinyathelo ngesinyathelo:

1. Dweba amaphoyinti amabili okuseka.
2. Buyela emuva ibanga elithile bese udweba i-ellipse.
3. Manje dweba imigqa emibili phezulu futhi futhi udwebe i-ellipse.
4. Sula umgqa ongaphezulu, uzothola epanini elingaphakathi.
5. Manje faka amaphuzu amabili afanayo ngemuva kwalesi sibalo.
6. Dweba i-ellipse futhi uhambe kuwo imigqa emibili phansi, nelinelayini eyodwa kuphela kubalo lokuqala, futhi owesibili ubude obufunayo.
7. Dweba umugqa ovalwe ngezansi ukuvala ukuma kwesibili.
8. Dweba i-cylinder yesithathu ngakolunye uhlangothi ngendlela efanayo.
9. Manje dweba isithunzi. Kuzoba ngakwesokudla, ngakho-ke kuzo zonke izibalo zokuqothulwa kwesibindi zigcwalisa ngakwesokudla.
10. Ngezingxabano ezincane ngesimo segceke kusukela ekuqaleni komugqa ogobile, dweba isithunzi ebusweni bezinto.

Umsebenzi wakho usulungile. Sihlolisise indlela yokudweba isilinda ngesithunzi, ngezakhi eziningana esithombeni.

Ngomgomo ofanayo, ungakwazi ukudweba imibhoshongo eminingi ngokwengqondo yakho, okubaluleke kakhulu, ungasebenzisi umbusi futhi ungahambi kumanani okuqala ukuze uthole ivolumu isebenze.

Ukudweba isilinda etafuleni

Manje cabanga indlela yokudweba isilinda ngesimo. Ukudweba konke ngokufanele, thatha into yangempela bese uyibeka etafuleni. Futhi ukulungiswa okukhanyayo ukuze isithunzi sibe phansi kahle etafuleni, kuyilapho sasingekho esifushane noma eside.

Umdwebo onembile kunokwenziwa kwithebhulethi, ukudonsa kuso iphepha. Usayizi ofanelekayo wale divayisi ungama-30 ngo-40 cm.

Masihambe enkambweni yokudala isithombe:

1. Nquma indawo yokuma bese udweba "imigqa engabonakali" ye-cylinder yesikhathi esizayo.
2. Yakha isilinda, kuqala udwebe imigqa emibili efana, bese u-ellipse kusuka phezulu nangaphansi.
3. "Imigqa engabonakali" izophinde idingeke indawo efanele yokukhanya nesithunzi. Dweba imiphetho engabonakali ngakwesokunxele kwe-cylinder ukuze uqonde ukuthi yiziphi izindawo ezizoba mnyama futhi zilula.
4. Hatch ukuma kwalesi sibalo, emigqeni encane, ukuze kamuva kube lula ukuqeda imivimbo.
5. Gcwalisa isithunzi esidalwe ngaphambilini. Kufanele kube mnyama.
6. Manje udinga ukudweba indiza yetafula kanye nodonga lwangemuva. Ngaphezu kwalokho, udonga olungemuva luyoba mnyama kunetafula, kodwa lilula ngaphezu kwesithunzi esiyinhloko salo.

Ngakho-ke, ngokucophelela futhi kancane kancane ungadonsa isimo sesithathu. Akudingekile ukuthi lesi yisilinda, ungathatha ibhola noma i-cube.

Indlela yokudweba ukwakheka ngezinto eziningana

Ukuze uqeqeshe ikhono lakho, sebenzisa izinhlobo eziningana ngesikhathi esisodwa. Okokuqala, i-cube yinto enhle, futhi ngaphezulu kwayo ubeke isilinda. Lungisa ukukhanya ukuze isithunzi siwe kahle etafuleni, bese uqala ukudweba.

Indlela yokudweba isilinda kanye ne-cube ipensela:

1. Njengoba sinekhamera ngezansi, siqala ukuyidweba ephepheni. Ukuze udwebe kahle, qala udwebe isikwele sangaphambili, bese ubeka imigqa ehlukene ukuze unike ivolumu. Xhuma ngemuva komugqa, bese usula imiphetho engaphezulu.
2. Manje dweba isilinda. Inqubo yokwakhiwa kwayo ngeke ihluke kwezinye izinhlobo ezidlule, ngoba i-cube nayo iyindiza ephahleni.
3. Uma uhlela izibalo, susa imiphetho engaphezulu.
4. Sidlula emathunzini. Njengoba sinepiramidi emdwebeni, isithunzi esijwayelekile sizofana nesakhiwo sombhoshongo.
5. Dweba izithunzi zangaphambili kulezi zibalo ngokusho ukuthi ukukhanya kuwele kanjani.
6. Qedela umsebenzi ngodonga lwangasese kanye netafula.

Izingoma ezinjalo zingenziwa ngokuhluke kakhulu kuye ngesifiso sakho. Ngemuva kokuthi ufunde ikhono lokudweba ubujamo be-geometri, ungadonsa izinto eziyinkimbinkimbi noma izingqikithi.

Amathiphu wabaculi

1. Ukuze uqonde ukuthi ungadonsa kanjani isilinda ngendlela efanele, kungcono ukuthatha njengesisekelo into yangempela, ukulungisa ukukhanyisa kusengaphambili.
2. Kulula kakhulu ukudweba kuthebhulethi, ngoba ishidi ngeke lilahle.
3. Sebenzisa amapensela nge-degrees ehlukene yokuqina.
4. Ungasheshi lapho wenza izakhi, futhi uma kukhona okungahambanga, ungesabi ukuqala futhi.
