Pikse\u013cu \u0113vele<\/h1>\n

Pikse\u013cu \u0113vele, saukta ar\u012b par fragmentu \u0113veli, ir datora programmas veids, ko izmanto, lai datorgrafik\u0101 manipul\u0113tu ar atsevi\u0161\u0137u pikse\u013cu kr\u0101su un citiem atrib\u016btiem. Tas ir \u012bpa\u0161s \u0113tera veids, kas paredz\u0113ts darbam tie\u0161i ar pikse\u013ciem, kas ir att\u0113la vai ekr\u0101na s\u012bk\u0101k\u0101s vien\u012bbas. Pikse\u013cu \u0113not\u0101jus parasti izmanto m\u016bsdienu 3D grafikas dzin\u0113jos, lai rad\u012btu re\u0101listisku apgaismojumu, \u0113nas un citus vizu\u0101los efektus.<\/p>\n

Pikse\u013cu \u0113veles darbojas, pie\u0146emot ievades dati<\/a>, piem\u0113ram, pikse\u013ca kr\u0101su un atra\u0161an\u0101s vietu, un, izmantojot matem\u0101tiskus apr\u0113\u0137inus un algoritmus, nosaka \u0161\u012b pikse\u013ca gal\u012bgo kr\u0101su un citus atrib\u016btus. \u0160ie apr\u0113\u0137ini var b\u016bt diezgan sare\u017e\u0123\u012bti un var ietvert vair\u0101kus ievades datus, piem\u0113ram, tekst\u016bras, apgaismojuma datus un citu inform\u0101ciju par atveidojamo ainu vai objektu.<\/p>\n

Pikse\u013cu \u0113veles ir svar\u012bga m\u016bsdienu grafikas programm\u0113\u0161anas da\u013ca, jo t\u0101s \u013cauj izstr\u0101d\u0101t\u0101jiem rad\u012bt \u013coti re\u0101listisku un vizu\u0101li iespaid\u012bgu grafiku. Veicot manipul\u0101cijas ar atsevi\u0161\u0137iem pikse\u013ciem, izstr\u0101d\u0101t\u0101ji var rad\u012bt da\u017e\u0101dus efektus, s\u0101kot ar smalku kr\u0101su un apgaismojuma mai\u0146u un beidzot ar sare\u017e\u0123\u012btu dabas par\u0101d\u012bbu, piem\u0113ram, \u016bdens un uguns, simul\u0101ciju.<\/p>\n

Pikse\u013cu \u0113veles parasti tiek rakst\u012btas \u012bpa\u0161\u0101 programm\u0113\u0161anas valod\u0101, ko sauc par \u0113ve\u013cvalodu un kas ir izstr\u0101d\u0101ta t\u0101, lai tiktu optimiz\u0113ta konkr\u0113tai aparat\u016brai un programmat\u016bras platform\u0101m, kuras tiek izmantotas grafikas programm\u0113\u0161an\u0101. Izplat\u012bt\u0101s \u0113ve\u013cvalodas ir HLSL, GLSL un Cg.<\/p>\n

Kopum\u0101 pikse\u013cu \u0113veles ir b\u016btisks r\u012bks m\u016bsdienu grafikas programm\u0113\u0161an\u0101, kas \u013cauj izstr\u0101d\u0101t\u0101jiem rad\u012bt \u013coti re\u0101listisku un vizu\u0101li iespaid\u012bgu grafiku, ko var izmantot visda\u017e\u0101d\u0101kaj\u0101s lietojumprogramm\u0101s, s\u0101kot no videosp\u0113l\u0113m l\u012bdz zin\u0101tniskaj\u0101m simul\u0101cij\u0101m un beidzot ar virtu\u0101l\u0101s realit\u0101tes vid\u0113m.<\/p>","protected":false},"excerpt":{"rendered":"
