I-Digitizer: yintoni na, indlela isebenza ngayo, njani isebenza ngayo

Iimarike zamashishini zanamhlanje zizele iintlobo ezahlukeneyo zezixhobo kunye nezixhobo zombane. Ukukhethwa kwabathengi, ngokuxhomekeke kwinjongo yokusebenzisa izixhobo. Emuva kuma-70s ekhulwini lokugqibela, ummangaliso we-teknoloji ubonakala kwi-yorhwebo yecandelo - i-digitizer. Yintoni na kwaye yintoni, namhlanje, hayi, kungekhona wonke umntu owaziyo. Masizame ukuqonda.

Malunga nesixhobo

Ukulahla imigaqo eqingqiweyo yobugcisa, i-digitizer inokuchazwa njengepilisi ecacileyo eguqulela umfanekiso ogqityiweyo, iphepha okanye i- vector ibe yifomati yedijithali. Kodwa musa ukudibanisa ne-scanner evamile.

I-digitizer inomxholo wesithinteli (empeleni ithebhulethi) kunye nefowuni yomzobo (ipen, ipolisi, isikhombisi, njl.). Umsebenzi kweso sixhobo unokufakwa kwizinto ezimbini:

• Ukubeka umfanekiso kwiskrini;
• Ukulungelelanisa izilungiso zeepeni okanye isikhombisi kwithebhulethi.

Kwimeko yezobume, ufuna kuphela ukuba ngumnini wefestile.

Iintlobo

I-teknoloji yokufaka ulwazi olucacileyo kumagcisa ahluke. Kule nkalo, kukho iintlobo ezintlanu zezixhobo:

1. Acoustic. Le ngenye yezibhebhile zokuqala ezibonakalayo. Iphoyinti yokudweba eveliswa ngokubizwa ngokuba yiintlanzi ezivakalayo ezibambe iifowuni zekrini. Ngaloo ndlela, isixhobo sizimisele ukulungelelanisa ulwazi. Impendulo ebalulekileyo yokusebenza kwithebhulethi kukuba igalelo lenkcazelo ludingeka lenziwe ngokusisicacisa, kuba ingxolo ye-acoustic yayingonakalisa umfanekiso. Olu hlobo lwe-digitizer luyaziwa ngokuveliswa kweenombolo zezixhobo ngaphantsi kwegama eliqhelekileyo le-Spark Tablet.
2. I-Electromagnetic. Ukuqulunqwa kwala macwecwe kwakulula kakhulu kwaye kuvelisa ngakumbi kunamathotho angaphambili. Ngaphantsi kwendawo yesikrini yadlula i-wire mesh, ikhupha izibonakaliso ezibuthathaka ze-electromagnetic. Intsiba yababamba, kwaye ke kwenzeka ukulungisa indawo yayo. Olu hlobo lwamadivaysi lubandakanya i-RAND Tablet, eyavela ngo-1964.
3. Isalathisi esicacileyo. Umgaqo ofanayo wokufakelwa kwe-electromagnetic wasetyenziselwa, kuphela kulezi zixhobo iingcingo zetambo ezazisasazwayo kwaye zamkela. Ukufakwa kolwazi kwenzeka xa ipenki igxininiswe kwaye ingaqhagamshelwanga. Idivaysi yokudweba ayifuni amandla. Kwakuyimpumelelo yobugcisa. Umzekelo weso sixhobo unokuba yi-tablet yeWacom.
4. Isikhethi esisebenzayo. Kule fowuni, i-generator yesiginali idluliselwa kwipeni. Ngoko ke, ufuna ukutya. Iimpawu zombane zivelise umfanekiso ogqithisayo kunezitshixo ze-electromagnetic. Olu hlobo lwezixhobo lwenziwa nguFinPoint Innovations.
5. Chukumisa i-digitizer - ezi zixhobo zanamhlanje. Ngaphantsi kwesikrini, ziqulethe iifowuni zokucwangcisa. Bahlukaniswe ngumsila omncinci. Ngaphantsi kwengcinezelo kwiinguqu zokuqhuba ipentiki. Iskrini esichukumisayo siyakwazi ukulungiselela ukudibanisa kunye nombane oshukumisayo weskrini sokudweba. Ezinye iinkqubo zikuvumela ukuba uhlaziye izinto ze-3D.

Kakade, ugxininiso kufuneka lubekwe kwicandelo lokusetyenziswa kwezixhobo zentliziyo. Ngokwehlobo lokukhangela ulwazi, i-ultrasonic, i-magnetic kunye ne-laser touch screen-digitizer iyahluka. Iyokuqala ayichanekanga kwaye inokwethenjelwa, kuba isantya sesandi apha sixhomekeke kwiqondo lokushisa, uxinzelelo lomoya kunye nezinye iziganeko ezijikelezayo.

Iimpawu zokugqala zamagnetic zichanekile ngakumbi, kodwa zixhamle kwizinto zetsimbi ezikufutshane (izihlalo, iikhomputha, izixhobo ezahlukeneyo). Ukuphazamiseka okunjalo kunokubangela ukuphazamiseka komfanekiso.

Kwaye, ekugqibeleni, i-laser digitizers yilezona zichanekileyo, kodwa zibiza namhlanje. Nangona kunjalo, ezi zixhobo nazo zinemiqathango. Abakwazi ukukhangela izinto ngeendawo ezibonakalayo, ezikhanyayo okanye ezixubileyo.

Ukongeza, namhlanje kwimarike yobugcisa unokufumana ama-digitizers anzima kwaye aguquguqukayo. Ezi zilandelayo zenziwa ngowe-1994. Ziyakhanya, zihambelana ngakumbi xa zithuthwa. Ukunikezelwa kwamandla kuzo kungabhalwa ngaphakathi okanye ngaphandle.

Ukhetho

Kubalulekile ukukhumbuza, xa ukhetha i-digitizer, ukuba le yicandelo elibi kwaye libiza kakhulu kufuneka lihlangabezane ngokukhawuleza neemfuno zomntu ngamnye. Kubalulekile ukuba ukuthembeka kwangaphandle kuhambelana neempawu zangaphakathi. Abaqhubi bekhwalithi, inkxaso kwiprojekti efunekayo kunye nefowuni efanelekileyo-ezi ziintlobo ezintathu ezikhethiweyo ekufuneka kukhethwe ngumthengi. Iinkampani zanamhlanje-iinkokheli ekuveliseni i-digitizers kwimarike yobugcisa yiGenius. Hitachi, CalComp, Wacom. Benza amacwecwe amacwecwe ahlukeneyo, inkqubo yokusebenza, idiagonal.

Ngokwahlukileyo kuyimfuneko ukuthetha malunga nezixhobo zokukhomba.

Baxhasi

Namhlanje, ukubonisa (okanye ukudweba) izixhobo zimelelwe ziintlobo ezimbini: izikratshi kunye neentsiba. Iyokuqala iyathandwa kakhulu. Ngokuxhomekeke kwimodeli, banokuba nama-4, 8, 12 okanye 16 amaqhosha. Nangona kunjalo, abanye abavelisi (umzekelo, i-One Graphics) bongeza enye iqhosha - "ebaluleke kakhulu". Kodwa, njengokuba kukho ukubonisa, ilula ifowuni, elula ngakumbi, ethembekileyo kwaye ethandwa kakhulu kubasebenzisi. Ngoko ke, izixhobo ezine ezineqhosha ziphumelele ngakumbi kunezinye zazo ezihamba phambili. Ezi ndlela ziseCalComp.

Ngokweengcali, ukukhethwa kwesikhombisi kufuneka kudibaniswe nje kuphela ngokukhululeka kolawulo kunye nenani lamaqhosha, kodwa lidibanisa neenkqubo ezisetyenzisiweyo. Kule meko, kufanelekile ukuthetha nge-AutoCAD.

Iintsiba

Ezi zixhobo zibhekwa njengento elula kwaye iyabuhlungu. Banikela kuphela enye, amabini okanye abathathu amaqhosha kwaye baphendule kwingcinezelo yesandla. Iintsiba zixhobo ezifanelekileyo zokudweba zabaculi kunye neentengiso. Isilinganiso soxinzelelo kwipeni sibonakaliswe ngenguqu ebunini bomgca, umbala, umthunzi. Emva kokuba usebenzise olu qhinga, umsebenzisi unokuxelisa ukudweba nge-watercolor, iipende zeoli okanye i-tempera. Nangona kunjalo, iiprogram ezizodwa zifunekayo ukuphumeza loo mveliso.

Ukhetho lweentsiba luzimisele ngokuzenzekelayo. Abanye abasebenzisi banjengazo zixhobo iifayile yeWacom ebonisa imifanekiso. Zincinci kwaye zilula. Enye ukujonga iintlobo ezinzima kunye neengqiqo ezinokulinganisela eKurta.

Zonke iifowuni ezikhombayo zingabhunqa kwaye zingenazintambo. Ezi zilandelayo zifuna amandla avela kwiibhetri, kwaye ngoko ke zinzima. Isilingo esiyimpumelelo sokulungisa oku kulahleka siye saba yimodeli enegunya langaphandle.

Nangona kunjalo, ungayikhohlwa malunga neentsiba ezingabonakaliyo ukusuka kumenzi Wacom, owona mkhosi, kungekhona umniki. Enyanisweni, ezi zixhobo azixhomekekanga kwingcinezelo.

Imiba yabathengi

Akunzima ukuqikelela ubuninzi bezinto ezinokuthi i-digitizer inayo. Yintoni na kwaye yintoni na yona-imibuzo ebalulekileyo yabathengi. Injongo yaso ephambili ngumsebenzi wobugcisa obungcali, apho kuyimfuneko ukuguqula ukuhamba kwesandla somqhubi kwimifanekiso yezedijithali. Ngoko ke, kulula kakhulu ukucacisa abaphulaphuli bemfuno. Ziyi-designers, abaculi bekhompyutheni, abenzi bezilwanyana, abakhi bezakhiwo, abadinga ukuyila ngokuzenzekelayo. Nangona kunjalo, nakwikhulu leminyaka elidlulileyo, i-digitizer yefowuni yayisetyenziswa kakhulu kwizorhwebo. Namhlanje le nqanaba inokuxhalabisa indawo yokuhlala, izithuthi, njl.

Kukho imibuzo apho abathengi abavame ukubuza: "Yintoni abanokuyenza kunye nabagqalayo kunye kwaye kutheni bahlala bebuthe ndawonye?" Apha unokwenza umfanekiso wokukhangela kunye nomshicileli. Ukuba i-digitizer ifumana kwaye idibanise ulwazi, emva koko umsebenzisi angenza utshintsho kumfanekiso kwikhomputha ngoncedo lweeprogram ezithile, abacebi bahlobo oluthile lwabashicileli. Banikezela ngolwazi kwifomati yedijithali ukuya kuphelile, iphepha. Ezi zixhobo ziyahluke kwiindidi, iimpawu, njl.

Isishwankathelo

Kulula, kucace kwaye kufinyeleleke kubo bonke abaphathi-mhlawumbi, uphawu olubaluleke kakhulu, olune-digitizer. Yintoni na oko kuyifunayo, sifunde. Kucacile ukuba akukho mfanekiso wezo zixhobo okwamanje. Ngokuqinisekileyo, unokusebenzisa ama-scanners eziqhelekileyo. Nangona kunjalo, kwi-design yezobugcisa ze-3D, i-digitizers ihlala ingcono kakhulu.
