Hom Computer Graphics

Yuav ua li cas hom ntawm computer graphics? Muaj ob lub ntsiab chav kawm ntawm graphics siv nyob rau hauv lub computer kev lag luam: two-dimensional (2D) thiab peb-dimensional (3D). 2D graphics, nyob rau hauv lem, yog muab faib mus rau hauv vector thiab raster. Sim kom to taub txog dab tsi cov computer graphics yog txawv los ntawm txhua lwm yam.

raster graphics

Peb pib nrog ib tug raster hom. Nyob rau hauv kev ncaj ncees nws yuav tsum tau muab sau tseg tias CG cov me nyuam yaus muab nws tso rau bitmaps. Qhov no txoj kev ntawm txoj kev ua dluab siv ib tug kab sib chaws ntawm pixels, qhov twg txhua lub caij muaj ib tug txheej ntawm tsis (brightness, xim code, cov theem ntawm transparency) muaj teeb meem loj zoo, raws li zoo raws li lub continuation ntawm cov zoo, tsis muaj tsawg tseem ceeb tsis zoo.

Simplicity ntawm lub hauv paus ntsiab lus ntawm txoj kev ua mesh wraps lub cev tsis nce los yog yuav txo tau cov uas ua daim duab. Yog hais tias nws yog significantly txo, poob khoom, yog tias muaj zog, yuav tshwm sim monstrous pixelation. Koj xav mus xyuas? Download tau los ntawm cov Internet cov duab thiab zoom nws mus rau lub nqi siab tshaj plaws uas yuav muab rau koj editing. Yog hais tias koj qhib nws nyob rau hauv lub qub Xim - muaj ib txhis mus kom ze 800%, vim li cas koj xav tau.

Yuav ua li cas yog interesting, lub ntsiab disadvantage ntawm "Dot" yog nws cov ntsiab kom zoo dua yog, raster duab tsis tas yuav suav txhua txhua lub sij hawm. Suffice nws ib zaug coj nyob rau hauv lub computer, thiab ces nws yuav tau muab cia rau muaj unchanged, uas tsis yog lub vector graphics uas peb tau raws li nyob rau hauv lub thib ob yog ib feem ntawm qhov tsab xov xwm.

Thov bitmap graphics yog qhov txhia chaw: nyob rau hauv lub printing kev lag luam, hauv TV, nyob rau hauv video ua si thiab xinesmas, zoo, thiab, ntawm chav kawm, hauv Internet.

Vector graphics

Creation ntawm computer graphics siv vector ua algorithms muab cov artist ib tug lossis loj lub sij hawm. Dluab tej zaum yuav dawb do tig thiab scaled, yog li tsis muaj distortion los yog deterioration nyob rau hauv qhov zoo ntawm cov uas ua khoom tsis tshwm sim. Tab sis cov nuj nqis yog mus txog heev ib tug nqi siab. Txhua lub sij hawm koj hloov daim duab nws yog laij dua, yog li ntawd thaum ib tug loj tus naj npawb ntawm ntau vector ntsiab ntawm qhov screen, rau simultaneous redrawing Tej zaum yuav ua lub hwj chim.

Vim hais tias ntawm nws cov tseem vector graphics yog tsuas yog siv nyob rau hauv lub tsim ntawm logos, nyob rau hauv fonts thaum nqus tas luav cim rau lub series, nyob rau hauv advertising, tus tsim, thiab lwm yam

Peb-dimensional graphics.

Hais txog tej hom ntawm computer graphics ob raster thiab vector yuav tham endlessly, tab sis muaj ntau heev tshaj dua kev nthuav hom - peb-dimensional graphics.

Yog hais tias nyob rau hauv lub yav dhau los, ob-dimensional embodiments, tej daim duab caij yog piav xwb nyob rau hauv ob coordinates nyob rau hauv 3D los piav rau txoj hauj lwm ntawm txhua tus taw tes twb yuav tsum tau peb coordinates. Yog li, nyob rau hauv kev txiav txim rau ntawm cov square twv rau ib daim ntawv ntawm daim ntawv mus ua lub voos xwmfab rau nws uas twb muaj lawm tsis tau mus ntxiv xwb ib tug ntxiv.

Yog hais tias koj twb pom tus naas ej movie "Avatar", ces koj yuav tsum tau xav kom koj paub tias nws twb tag tsim nyob rau hauv computer uas siv cov peb-dimensional graphics. Thiab yuav luag tag nrho cov tshwm sim ntawm qhov screen PC thiab console kev ua si yog zoo ib yam li cov neeg kho ntawm peb-dimensional qauv. 3D graphics yuav tsum tau ib tug ntau ntawm laij hwj chim los kav tsis muaj tus tso tawm cov duab, yog li tsis txhob tso tseg rau ib pliag nrhiav cib fim rau optimize thiab leeb ua hauj lwm nrog hom ntawv no. Tab sis, Tu siab, lub uas nws kim heev kev loj hlob ntawm txoj kev tau prevailed tshaj khaus. Muaj peev xwm rau cov zauv graphics phaib, yog nce cov nqi ntawm cov nco thiab processor zaus.

xaus

Tag nrho cov hom ntawm cov computer graphics yog siv qhov txhia chaw. Yog li ntawd hais tias cov kev tshawb no ntawm cheeb tsam no ntawm tib neeg kev ua si - ib tug tseem ceeb thiab pheej qoj ib ce.
