Loluphi uhlobo lomfanekiso owenziwe sisipili esiyiconvex?
A Isibuko se-Acrylic convex, eyaziwa ngokuba yi-fisheye sheet okanye i-divergent mirror, isibuko esigobileyo esine-bulge phakathi kunye nesimo esiyingqayizivele.Ngokuqhelekileyo zisetyenziswa kwiintlobo ngeentlobo zezicelo ezifana nokucupha ukhuseleko, ukubeka iliso kwindawo eyimfama, kunye neenjongo zokuhombisa.Enye yeempawu eziphambili zezibuko zeconvex luhlobo lomfanekiso abawenzayo.
Xa imitha yokukhanya ibetha aisipili esiconvex, ziyahlukana okanye zisasazeke ngenxa yokumila kwesibuko.Oku kwenza ukukhanya okubonakalisiweyo kubonakale kuvela kwindawo ebonakalayo emva kwesipili (ebizwa ngokuba yindawo ekugxilwe kuyo).Indawo ekugxilwe kuyo ikwicala elinye laloo nto iboniswayo.
Ukuqonda iintlobo zemifanekiso eyenziwe zizibuko zeconvex, kubalulekile ukubamba iingqikelelo zemifanekiso yokwenyani kunye nenyani.Umfanekiso wokwenyani uyilwa xa imitha yokukhanya idibana kwindawo ethile kwaye inokuboniswa kwiscreen.Le mifanekiso inokubonwa kwaye ifakwe kwiscreen okanye ngaphezulu.Kwelinye icala, umfanekiso wenyani uyakhiwa xa imitha yokukhanya ingahlangani kodwa ibonakala iyaphambuka kwindawo ethile.Le mifanekiso ayinakuboniswa kwiscreen, kodwa umntu obukeleyo unokuyibona ngesipili.
Isibuko seconvex senziwa umfanekiso wenyani.Oku kuthetha ukuba xa into ibekwe phambi kwe-aisipili esiconvex,umfanekiso owenziwe ubonakala usemva kwesibuko, ngokungafaniyo xa umfanekiso usenziwa phambi kwesibuko kwisibuko esisicaba okanye se-concave.Umfanekiso owenziwe sisipili esiyiconvex uhlala ume nkqo, oku kuthetha ukuba awusokuze ujikwe okanye ujikwe.Ubungakanani bayo bubuye buncitshiswe xa kuthelekiswa neyona nto.
Ubungakanani bomfanekiso wenyani buxhomekeke kumgama phakathi kwento kunye nesibuko seconvex.
Njengoko into isondela kufutshane nesibuko, umfanekiso obonakalayo uba mncinci.Ngokuchasene noko, xa into ihambela kude, umfanekiso obonakalayo uba mkhulu.Nangona kunjalo, umfanekiso owenziwe sisipili esiyiconvex awunakuze ukhuliswe ngaphaya kobukhulu beyona nto.
Olunye uphawu lomfanekiso owenziwe ngu aisipili esiconvexkukuba ibonelela ngommandla obanzi wokujonga kunesipili esicaba okanye esiconcave.Imilo yeconvex yesibuko ivumela ukuba ibonise ukukhanya kwindawo enkulu, okukhokelela kwintsimi ebanzi yokujonga.Oku kuluncedo ngokukodwa kwizicelo ezifana nezibuko zemoto ezingaboniyo, apho umqhubi ufuna i-angle yokujonga ebanzi ukuze abone izithuthi ezisondelayo ukusuka ecaleni.
