Ziziphi iintlobo zemifanekiso oyaziyo?

Kwicandelo "imifanekiso yekhompyutheni" sifunda iindlela zokudala ezintsha kunye nokucwangcisa iifayile ezibonakalayo ezikhoyo ngokusebenzisa i- hardware ekhethekileyo . Ukusebenza kunye nedatha enjalo, inani elikhulu leeklasi zenzelwe.

Ezi ntlobo zemibala elandelayo zivela:

- vector;

- Raster;

- fractal;

- ezintathu-ububanzi;

- isimboli.

Olu hlobo lusetyenziswanga ixesha elide, ngoko kule nqaku siza kuthetha kuphela ngeentlobo ezine.

Iindidi ezicacileyo zeemifanekiso zinika i-specific specifics of working with them. Ngoko, umzekelo, ukusebenza negraphic graphics kubonisa, kunoko, ukusetyenziswa kwayo, kunokudalwa. Kwaye kunye nevector, ngokuchaseneyo, indalo engaphezulu kunokusetyenziswa.

Makhe siqwalasele ngokubanzi iinkcukacha ezahlukeneyo.

1. Vector

Into ephambili ngumgca. Umgca uhamba ngqo okanye i-curve ayibalulekanga nakakhulu. Ngokuncediswa kwemigca yonke into yeemifanekiso zentengiso zenziwe. Izinto ezilula ziyinkimbinkimbi. Kuvela ukuba yonke imigca ifakwe.

Iipropati zemizila ziquka ezi zikhombisi:

Imilo;

- Ukunyaniseka;

Umbala;

Umntu.

Ukuba umgca uvaliwe, ke unendawo yokuzalisa. Umgca ongagqitywanga unemigangatho emibili yee-vertices-nodes, ezibuye zineempahla zazo.

2. Ukukhawuleza

Apha, ngokuphambene nombono ongaphambili, into ebalulekileyo yile ngongoma. Ukuze umfanekiso weskrini - ipixel. Unayo impahla yebala kunye nokubekwa.

Ukungalungi kweefoto ze- raster :

- thatha indawo eninzi kwimemori yekhompyutha;

- akunakwenzeka ukwandisa umfanekiso ukuqwalasela kakuhle izinto.

3. I-Fractal

Umfanekiso kwigrafu ye-fract iyiqela lezinto ezifanayo ezixhunyiwe kunye. Ukwakha imidwebo enjalo kukunceda i-algorithms ekhethekileyo okanye amafomula. Ukuguqulwa kweemifanekiso kunokwenzeka xa kufakwa iinombolo kwi-algorithms okanye iiparamitha kwiifomula.

4. I-three-dimensional

Into yokufunda i-3D-imifanekiso yindlela yokwakha imodeli ye-3D yezinto ezithile nezinto. Kubalulekile ukuba bahambelane kangangoko kunokwenzeka kwiimpawu zabo zangempela. Ngenxa yolu hlobo, imilo eyahlukeneyo kunye neendawo ezenziweyo ziyasetyenziswa.

Ukufunda iintlobo zemifanekiso, kufuneka uqaphele ezi ngcamango ezilandelayo:

Imvume. Kukho isisombululo seskrini, umshicileli kunye nomfanekiso ngokwawo. Xa usebenza nemifanekiso, oku kubalulekile. Lo ngumfanekiso wepropati. Iyunithi yokulinganisa ngamacotshi nge intshi. Useka isisombululo ngexesha lokudalwa komfanekiso kumhleli okanye ngexesha lokuskena.

Ngaphantsi kobukhulu bomzimba bomfanekiso uqondwa ubude bayo nobubanzi. Inokulinganiswa ngamaphikseli, kwaye ngamasentimitha (millimeters, metres, njl.). Inikwa kwakhona ngexesha lokudala umzobo kwaye igcinwa nayo. Ukuze umfanekiso uhlelwe ukuba uboniswe, ubungakanani bobukhulu buboniswe kwiipikseli. Oku kukuvumela ukuba ubone ukuba yiyiphi inxalenye yeskrini eya kuthatha. Ubungakanani bomfanekiso oza kuprintwa buboniswe kwiiyunithi ezide ukuqonda ukuba kuza kuthatha indawo ephilileyo ukuze kubekho iphepha.

Zonke iintlobo zemizobo zinezinto ezintle kunye nezibi. Kodwa, nangona kunjalo, ngamnye wabo namhlanje unendawo yaso yesicelo. Iifayile ze-raster kuba - ukubuyiselwa kwezithombe, umzekelo, kunye negraphic vector-ukudala ibhanti yokukhangisa. Mhlawumbi kwikamva elizayo ihlabathi liya kuba nolwazi olutsha uhlobo lweekhompyutheni zekhompyutha. Ngubani owaziyo?
