Izinhlobo Computer Graphics

Yiziphi izinhlobo eseyi? Kukhona namakilasi ezimbili eziyinhloko ihluzo obusetshenziswa embonini kukhompyutha: lamabili (2D) kanye ngakuthathu (3D). ihluzo 2D yena, ihlukaniswe Vector kanye raster. Zama ukuqonda ukuthi yini lezo zinhlobo eseyi zihlukile komunye nomunye.

raster ihluzo

Asiqale nge format raster. Uzokwenza kufanele kuphawulwe ukuthi izisekelo CG wasibeka bitmaps. Le ndlela yokwakha izithombe usebenzisa igridi yama-pixels, lapho element ngayinye has a isethi nemingcele (ukukhanya, ikhodi umbala, lizinga obala) kunezinzuzo abalulekile, kanye ukuqhubeka kwalezi zimo ezinhle eyayikuzo, nebubi kungekho zincane.

Ukwenza Izinto Zibe Lula izimiso obumba anezikhala ezisonga ukungakwazi ukwandisa noma ukunciphisa isithombe. Uma is kakhulu ziyancipha, izinto elahlekile, uma yanda, izovela pixelation eyesabekayo. Ufuna ukuhlola? Landa kusuka ku-Inthanethi yimuphi umfanekiso futhi usondeze ukuze seqiwe ukuthi izokunikela kwemaphutsa. Uma ulivula ku Paint evamile - kukhona indlela maximal 800%, nje okudingayo.

Kuyini ezithakazelisayo, ububi eyinhloko "Dot" kwaba inzuzo yayo esemqoka is, raster image akudingeki ukubala njalo. Engingakusho nje uma ukuletha in computer, bese-ke izogcinwa khona azizange zishintshe, engesiyo ihluzo Vector ngawo esibathola ingxenye yaleli Isihloko sesibili.

Sebenzisa bitmap ihluzo kuthiwa yonke indawo: abasembonini yokunyathelisa, kumabonakude, imidlalo yama-video kanye cinema, kahle, futhi-ke, i-Internet.

vector ihluzo

Ukudalwa eseyi usebenzisa Vector ukucutshungulwa algorithm unikeza umculi ithuba elikhulu. Imifanekiso kungenzeka ajikelezwe ngokukhululekile futhi kukalwa khona, ngaleyo ndlela akukho ukuhlanekezela noma Oqala ukungezwa aze agcine izinga umkhiqizo okuholela ayenzeki. Kodwa lezi zibalo usufinyelelwe ngempela imali eshisiwe. Ngaso sonke isikhathi uma ukushintsha isithombe it is recalculated, ukuze kuthi lapho inani elikhulu Vector izakhi ezahlukene esikrinini, ngoba redrawing kanyekanye kungadinga ngaphezulu ukucubungula amandla.

Ngenxa ngokucacile Vector yayo ihluzo ikakhulukazi elisetshenziswa design logo, e amafonti lapho ukudweba cartoon abalingiswa ngochungechunge oluthi, ezikhangisweni, umklamo, njll

ihluzo Three-ntathu.

Mayelana izinhlobo ezifana computer kokubili raster kanye Vector ungakwazi ukukhuluma phakade, kodwa kukhona uhlobo ngisho mnandi - Ihluzo ngakuthathu.

Uma esikhathini esedlule, embodiments mgudumbili, iyiphi isici isithombe kuchazwa kuphela izixhumanisi ezimbili ku-3D ukuchaza isikhundla iphuzu ngalinye kakade kudinga izixhumanisi ezintathu. Ngakho, ukuze esigcawini idwetshwa ephepheni ukwenza cube nemingcele yaso ekhona udinga ukwengeza ezengeziwe eyodwa kuphela.

Uma uke wazibona movie adumile "Avatar", khona-ke uyoba nesithakazelo ukwazi ukuthi sadalwa ngokuphelele kukhompyutha nokusetshenziswa ihluzo ngakuthathu. Futhi cishe yonke ivele PC screen nokududuza imidlalo iyefana abahleli onobuhle ngakuthathu. 3D lidinga Computing amandla zokunikeza kwemigomo isithombe ukuboniswa, ngakho abayeki umzuzu ukufuna amathuba nokwandisa futhi ukusheshisa umsebenzi nale format. Kodwa, ngeshwa, ukuthuthukiswa olubanzi indlela uye lamnqoba okukhulu. Ikhono elandisiwe lezinto ezisebenzisa i-sicubungula ihluzo amakhadi, bayanda amanani inkumbulo processor imvamisa.

isiphetho

Zonke izinhlobo eseyi asetshenziswa yonke indawo. Ngakho ukuthi ukutadisha le ndawo yizenzo zabantu - umsebenzi ewusizo kakhulu futhi ethembisa.
