Types of Computer Graphics

Zeziphi iintlobo ze computer? Kukho iindidi ezimbini eziphambili yemizobo ezisetyenziswa computer: emacala-mabini (2D) kunye-ntathu (3D). iigrafiki 2D, yena, yahlulahlulwe kumda wesangqa kunye yeraster. Zama ukuqonda ukuba yintoni ezi ntlobo ze computer zahlukile enye kwenye.

yemizobo yeraster

Masiqalise ngokwendlela yeraster. Kubulungisa kufanele kuqatshelwe ukuba iziseko CG wayibeka ye bitmaps. Le ndlela yokwakha imifanekiso usebenzisa Igridi pixels, apho ilungu ngalinye unesethi parameters (yobumhlophe, ikhowudi umbala, inqanaba elubala) ineendlela ebalulekileyo, ngokunjalo nokuqhubeka ezi eziluncedo, ezingeloncedo, abalulekile ngaphantsi.

Elula imigaqo zokubumba umnatha usonga i ukungakwazi ukwandisa okanye ukunciphisa umfanekiso ngenxa. Ukuba yehliswe kakhulu, izinto elahlekileyo, ukuba kunyuke, kuya kuvela pixelation enkulu. Ufuna ukuhlola? Layisha ukusuka kwi Internet nawuphi na umfanekiso uze usondeze ukuba ixabiso eliphezulu ukuba uza kukunika kunye nohlelo. Ukuba uvule kwi Paint yesiqhelo - kukho indlela nyanga ezinintsi 800%, kanye le nto uyifunayo.

Yintoni umdla kukuba, indlala enkulu "Dot" yaba ingenelo yayo eyintloko, umfanekiso yeraster akuyomfuneko ukuba babale lonke ixesha. Kwanele kanye ukuba ungenise computer, yaye ke iya kugcinwa khona ingaguqukanga, ingeyo yemizobo wesangqa ngayo esidibana kwinxalenye yesibini kweli nqaku.

Faka yemizobo ye bitmap buphela ndawo zonke; baprintayo, kumabonwakude, xa ivideo imidlalo cinema, kakuhle, yaye, ke, i-Internet.

yemizobo vector

Indalo computer usebenzisa ubuchule esiyua processing unika umzobi ithuba enkulu. Imifanekiso ukuze ngokukhululekileyo ajikelezwe lize lithotywe, ngoko akukho ephazamisa okanye Ukonakala kwenye kukulunga lwemveliso onesiphumo lungenzeki. Kodwa la manani zifikelelwe kakhulu ngexabiso eliphezulu. lonke ixesha utshintsha umfanekiso kubhaliwe zibalwe ngokutsha, ukwenzela ukuba xa inani elikhulu lweziqalelo ezahlukeneyo kumda wesangqa kwikhusi, ngokuba redrawing ngaxeshanye kungafuna amandla engaphezulu inkqubela.

Ngenxa imizobo yalo Okukodwa kumda wesangqa busetyenziswa kakhulu kuyilo iilogo, lwamagama xa uzoba abalinganiswa ikhathuni ngenxa thotho, kwi ntengiso, uyilo, njl

imizobo-olunemigqaliselo ezintathu.

Malunga iintlobo enjalo computer yemizobo zombini yeraster kunye kumda wesangqa uyakwazi ukuthetha ngonaphakade, kodwa kukho uhlobo nokuba ezinomdla kakhulu - mifanekiso-ntathu.

Ukuba ongaphambili embodiments, ezikumila kumacala mabini, nawuphi na umfanekiso ichazwa kuphela zilungelelanise ezimbini 3D ukuchaza indawo ingongoma nganye sele ifuna ezihambelanayo ezintathu. Ngoko ke, ukuze ukusuka isikwere ezotywe ephepheni ukwenza ibokisi parameters zayo ezikhoyo kufuneka wongeze ezinye enye kuphela.

Ukuba siyibonile movie odumileyo "Avatar", ngoko ke uya kuba nomdla ukwazi ukuba wadalwa ngokupheleleyo kwi khompyutha kunye nokusetyenziswa yemizobo-ntathu. Kwaye phantse zonke ivele kwi PC kwikhusi kunye console imidlalo iyafana abahleli iimodeli-ntathu. yemizobo 3D kufuna ixesha elininzi computing igunya lokuba enze Ipharamitha umfanekiso oboniswe, ngoko musa ukuma umzuzu bafune amathuba nokwandisa nokukhawulezisa umsebenzi kunye kule fomati. Kodwa ke, ngelishwa, uphuhliso ngokubanzi indlela lundoyisile phezu kakhulu. Ukwandisa amandla nokuhlawulwa cards imizobo, bayanda izixa yinkumbulo iprosesa rhoqo.

isiphelo

Zonke iintlobo computer zisetyenziswa kuyo yonke indawo. Sothi sifundo sale ndawo zezinto ezenziwa luluntu - umthambo luncedo kakhulu kwaye zithembisa.
