Uma into ibekwa phambi kobuso besibuko obuyi-convex obubonisa ukukhanya, isibuko esiyi-convex sizokwakha isithombe sale nto. Uma ibanga lento elivela esibukweni esiyi-convex laziwa, udweba kanjani ukwakheka kwesithombe sale nto? Ukuze kucaciswe lokhu, ake sithi into ibekwe phambi kwesibuko esiyi-convex. isibuko esijiyile njengoba kuboniswe esithombeni esingezansi.
Isihlokwana:
Umugqa ophuzi = isibuko esijiyile
Umugqa oluhlaza okwesibhakabhaka = i-axis eyinhloko
Umcibisholo (oluhlaza okotshani) = into
R = isikhungo sokugoba kwesibuko esiqondile
f = ukugxila kwesibuko esijiyile
Izithunzi zezinto zitholakala ngokubonisa zonke ukukhanya ezidlula entweni, kodwa lokhu akunakwenzeka ngoba kuzoba nemigqa eminingi emele imishayo yokukhanya. Ukuze kube lula, kukhethwa imishayo yokukhanya embalwa nje ukuze imele yonke imishayo yokukhanya edlula entweni. Uma sibheka ukuthi lesi senzakalo sihilela ukukhanya okukhanyayo ufulawa umthetho wokubonakaliswa kokukhanya kumele kulandelwe lapho kudweba ukwakheka kwesithunzi.
Imisebe emithathu yokukhanya noma imisebe ekhethekile yezibuko eziqondile
Ukukhanya okukhethekile 1:
Umsebe 1 noma umsebe wokukhanya 1 oza esibukweni esijiyile uboniswa njengohambisana no i-axis eyinhloko bese ithinta ingxenye ephezulu yento, bese iboniswa yisibuko esijiyile lapho kubonakala khona ukuthi ukukhanya okukhanyayo kuvela khona. indawo yokugxila (f)Ukukhanya kwesigameko nokukhanya okubonakalisiwe kumele kuhlangane umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa.
Ukukhanya okukhethekile 2:
Umsebe wokukhanya 2 noma umsebe wokukhanya 2 oza esibukweni esijikijelwayo uboniswa uthinta unqenqema oluphezulu lwento bese uqonda endaweni lapho i-axis eyinhloko ihlangana khona nesibuko esijikijelwayo, bese umsebe wokukhanya uyabonakala. Umsebe wesigameko kanye nomsebe ojikijelwayo kumele kuhlangane. umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa.
Ukukhanya okukhethekile 3:
Umsebe 3 noma umsebe wokukhanya 3 oza esibukweni esijiyile uboniswa ubheke iphuzu eliphakathi lokugoba kwesibuko (R) bese ithinta unqenqema oluphezulu lwento, bese iboniswa yisibuko esijiyile njengokungathi umugqa wokukhanya obonisiwe uvela endaweni ephakathi yokugoba. Umugqa wokukhanya obonisiwe uhambisana nomugqa wokukhanya obonakalisiwe. Umugqa wokukhanya obonakalisiwe kanye nomugqa wokukhanya obonakalisiwe kumele kuhlangane umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakalisa. Uma ukukhanya kwesigameko kuhambisana nomsebe wokukhanya obonakalayo khona-ke umsebe wokukhanya kumele ube ngoqondile (90o) enobuso obuyisibuko obuyindilinga.
Ukwakheka kwesithunzi (imisebe emibili ekhethekile)
Ukwakheka kwesithunzi sento kungaboniswa kusetshenziswa imisebe yokukhanya emibili kuphela noma imisebe emibili ekhethekile, njengoba kuboniswe esithombeni esingezansi. Uma kusetshenziswa imisebe yokukhanya emibili, kunezithombe ezintathu ezingaba khona zokwakheka kwesithunzi.
Imisebe ekhethekile 1 no-2
Imisebe ekhethekile 1 no-3
Imisebe ekhethekile 2 no-3
Isithombe sokwakheka kwesithombe sento sisebenzisa imishayo emibili yokukhanya kuphela sidinga ukulungiswa ukuze silingane nebanga lento esibukweni esiqondile. Uma ibanga lento esibukweni esiqondile linjengoba lisesithombeni esingenhla, kunezindlela ezintathu zokudweba ukwakheka kwesithombe kusetshenziswa imishayo emibili yokukhanya kuphela. Uma ibanga lento esibukweni esiqondile lihlukile esithombeni esingenhla, isibonelo, into iphakathi kwephuzu eligxile kanye nendawo ephakathi nendawo egobile, khona-ke kungenzeka kungabi khona izindlela ezintathu zokudweba ukwakheka kwesithombe, kungase kube nezindlela ezimbili kuphela zokudweba.
Uma udweba ukwakheka kwesithombe sento ngesibuko esijiyile, ungakhetha indlela eyodwa futhi awudingi ukusebenzisa izindlela ezimbili noma ezintathu.
Ukwakheka kwesithombe (imisebe emithathu ekhethekile)
Ukwakheka kwesithunzi sento kungaboniswa kusetshenziswa imisebe yokukhanya emithathu noma imisebe emithathu ekhethekile, njengoba kuboniswe esithombeni esingezansi.
Uma ibanga lento esuka esibukweni esijikijelwayo lingekho njengoba kuboniswe esithombeni, isibonelo uma into iphakathi kwesibuko esijikijelwayo nendawo egxile kuyo, noma into iphakathi kwendawo egxile kuyo kanye nendawo ephakathi kwesibuko esijikijelwayo, khona-ke akuqiniseki ukuthi ukwakheka kwesithombe sento kungachazwa kusetshenziswa amathuba amathathu noma izindlela ezintathu njengoba kuboniswe esithombeni. Kungenzeka ukuthi kunezindlela ezimbili kuphela noma izindlela ezimbili zokudweba ukwakheka kwesithombe. Sicela ubheke isibonelo sesithombe sokwakheka kwesithombe sento ngesibuko esijikijelwayo, lapho ibanga lento esuka esibukweni esijikijelwayo lihluka khona, esihlokweni. isithombe sesibuko esijiyile.
