Mhando Computer Graphics

Mhando kombiyuta Graphics chii? Pane mapoka maviri chikuru Graphics wakashandiswa kombiyuta indasitiri: maviri-dimensional (2D) uye-dimensional matatu (3D). 2D Graphics, akavapindurawo, rakakamurwa Vector uye Raster. Edza kunzwisisa kuti mhando iyi kombiyuta Graphics vakasiyana mumwe.

Raster Graphics

Ngatitange aine Raster format. In kururamisira zvinofanira kucherechedzwa kuti CG nheyo akaiisa bitmaps. Nzira iyi nokuumba mifananidzo kushandisa grid pamusoro pixels, apo mumwe ichocho akaronga kuti parameters (kupenya, ruvara code, padanho pachena) ane zvinokosha zvakwakanakira, uyewo kuenderera zvazvakanakira izvi, hapana zvishoma zvinokosha payakaipira.

Nyore zviga rokuumba pajira riya Achiputira nekusagona kuwedzera kana kutapudza zvichiguma mufananidzo. Kana yekudyidzana akaderedzwa, zvinhu vakarasika, kana zvawanda vachaonekwa monstrous pixelation. Unoda kuongorora? Download kubva Internet kwemifananidzo uye Zoom kuna kunonyanyisa ukoshi kuti achakupa fora. Kana kurivhura ari zvakajairika Paint - ipapo maximal kusvika 800%, izvo zvaunoda.

Chii kunakidza, mukuru zvakaipira "tira" yaiva kwayo chikuru nani ndiko, Raster mufananidzo havafaniri kuverenga nguva dzose. Zvakakwana kamwe kuti vauye kombiyuta, uye ipapo achava kuchengeterwa imomo kuchinja, izvo haisi Vector Graphics nako tikasangana chikamu ichi Nyaya yechipiri.

Shandisa bitmap Graphics vari kwose kwose: ari kudhindwa indasitiri, paterevhizheni, mitambo uye mabhaisikopo, zvakanaka, uye, chokwadi, Indaneti.

Vector Graphics

Creation kombiyuta Graphics kushandisa Vector kubudiswa algorithms anopa womufananidzo mukana hombe. Images anogona pachena zvayaitenderera paguyo uye scaled, saka hapana kusarurama kana kudzikira mune chatingatevedzera zvichizoita chigadzirwa hakuitiki. Asi nhamba idzi dziri zvasvika chaizvo mukuru mutengo. Pose iwe kushandura mufananidzo zvinonzi recalculated, saka kuti kana vazhinji siyana Vector zvinhu pamusoro chidzitiro, nokuti mawa redrawing kungada zvakawanda kugadzira simba.

Nokuda kwayo specificity Vector Graphics dzinowanzotsigi- kushandiswa magadzirirwe Logos, mune fonts kana pakuswedera katuni vatambi kuti series, ari kushambadza, magadzirirwo, etc.

Three-dimensional Graphics.

About mhando dzakadai kombiyuta Graphics sechinhu Raster uye Vector anogona kutaura nokusingaperi, asi pane kunyange kunakidza mhando --dimensional matatu Graphics.

Kana yapfuura, mbiri-dimensional embodiments, chero mufananidzo chaikosha inorondedzerwa chete Coordonatele maviri 3D kutsanangura nzvimbo imwe neimwe pfungwa kare inoda Coordinates matatu. Saka, kuti kubva pachivara wakavhomorwa pamusoro papepa kuti kuutio wayo huripo parameters vanofanira kuwedzera mamwe mumwe chete.

Kana ndamboona akakurumbira firimu "Avatar", ipapo iwe uchava kufarira kuziva kuti iye akasikwa zvachose kombiyuta nokushandiswa-dimensional matatu Graphics. Uye zvinenge zvose kuoneka pamadziro PC uye kunyaradzana mitambo dzakafanana Vapepeti-dimensional matatu yokutevedzera. 3D Graphics kunoda kadambari simba kushandura parameters yacho vakaratidza mufananidzo, saka regai kumira kunyange kwekanguva kuti kutsvaka mikana optimize uye mhanyisa basa pamwe urongwa ichi. Asi, zvinosuruvarisa kwakakura kukura nzira akunda pamusoro zvikuru. Inosimudzira kukwanisa processing Graphics makadhi, zvawanzwa uwandu okuyeuka processor maitikiro.

mhedziso

Ose kombiyuta Graphics anoshandiswa kwose kwose. Saka kuti kudzidza nzvimbo iyi yebasa evanhu - yaibatsira chaizvo uye zvinovimbisa muviri.
