Isihloko mayelana nemidwebo yemisebe yesibuko esijijekile
Uma into ingaphambili kwesibuko esijiyile esibonakalisa ukukhanya, isibuko esijiyile sizokwakha isithombe sento. Uma ibanga lento esibukweni esijiyile laziwa, ungadweba kanjani ukwakheka kwesithombe sento? Ake sithi into ingaphambili kwesibuko esijiyile, njengoba kuboniswe esithombeni esingezansi.
Umugqa ophuzi = isibuko esijiyile
Umugqa oluhlaza okwesibhakabhaka = i-axis eyinhloko
Umcibisholo oluhlaza = into
R = isikhungo sokugoba kwesibuko esiqondile
f = ukugxila kwesibuko esijiyile
Izithombe zezinto zitholakala ngokudweba yonke imisebe edlula ezintweni, kodwa lokhu akusebenzi kangako ngoba kuzoba nemigqa eminingi emele imisebe. Ukuze kube lula, kukhethwa imisebe embalwa nje ukumela yonke imisebe yokukhanya edlula entweni. Njengoba lesi senzakalo sihilela ukubonakaliswa kokukhanya, umthetho wokubonakaliswa kokukhanya kumelwe ulalelwe lapho kudweba ukwakheka kwesithombe.
Umdwebo wemisebe
1:
Umsebe 1 noma umsebe wokukhanya 1 oza esibukweni esijiyile udwetshwa ngokuhambisana ne-axis eyinhloko bese uthinta ingxenye engenhla yento,
bese kuboniswa yisibuko esijiyile, lapho umsebe wokukhanya uboniswa sengathi uvela endaweni egxile kuyo (f). Ukukhanya okungenayo kanye nokukhanya okubonakalayo kumele kugcwalise umthetho wokubonakaliswa kokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokubonakaliswa.
2:
Umsebe wokukhanya 2 noma umsebe wokukhanya 2 oza esibukweni esijiyile udonswa ukuze uthinte ingxenye engenhla yento,
futhi maqondana nendawo lapho kuhlangana khona i-axis eyinhloko nesibuko esijiyile, khona-ke ukukhanya kuyakhanya. Ukukhanya okungenayo kanye nokukhanya okukhanyayo kumele kugcwalise umthetho wokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokukhanya.
3:
Umsebe 3 noma umsebe wokukhanya 3 oza esibukweni esijiyile udonselwa endaweni ephakathi nendawo yokugoba kwesibuko (R) bese uthinta ingxenye engenhla yento,
bese kuboniswa yisibuko esijiyile njengokungathi ukukhanya okukhanyayo kuvela enkabeni yokugoba. Ukukhanya okukhanyayo kuhambisana nokukhanya okungenayo. Ukukhanya okungenayo kanye nokukhanya okukhanyayo kumele kugcwalise umthetho wokukhanya, lapho i-engeli yokwenzeka ilingana ne-engeli yokukhanya. Uma ukukhanya kuhlangana nokukhanya okukhanyayo, ukukhanya kumele kube okuqondile (90 o ) nobuso besibuko esijiyile.
Ukwakheka kwesithombe (imisebe emibili)
Ukwakheka kwesithombe kungadwetshwa kusetshenziswa imisebe emibili kuphela, njengoba kuboniswe esithombeni esingezansi. Uma usebenzisa imisebe emibili, kunezithombe ezintathu ezingakhiwa.
I-Ray 1 kanye ne-ray 2
I-Ray 1 kanye ne-ray 3
I-Ray 2 kanye ne-ray 3
Isithombe sokwakheka kwesithombe sisebenzisa imisebe emibili yokukhanya kuphela sidinga ukulungiswa ngebanga lento esibukweni esiqondile. Uma ibanga lento esibukweni esiqondile linjengoba lisesithombeni esingenhla, khona-ke kunezindlela ezintathu zokudweba ukwakheka kwesithombe sisebenzisa imisebe emibili yokukhanya kuphela. Uma ibanga lento esibukweni esiqondile lihlukile njengoba kuboniswe esithombeni esingenhla, isibonelo, into iphakathi kwephuzu eligxile kanye nendawo ephakathi nendawo egobile; khona-ke azikho izindlela ezintathu zokudweba ukwakheka kwesithombe, mhlawumbe kunezindlela ezimbili kuphela zokudweba.
Uma udweba ukwakheka kwesithombe ngesibuko esijiyile, ungakhetha indlela eyodwa futhi awudingi ukusebenzisa izindlela ezimbili noma ezintathu.
Ukwakheka kwesithombe (imisebe emithathu)
Ukwakheka kwesithombe kungadwetshwa kusetshenziswa imisebe emithathu yokukhanya noma imisebe emithathu, njengoba kuboniswe esithombeni esingezansi.
Uma ibanga lento esibukweni esijikijelwayo lingekho njengoba kuboniswe esithombeni, isibonelo, uma into iphakathi kwesibuko esijikijelwayo nendawo egxile kuyo,
noma into iphakathi kwephuzu eligxile kanye nesikhungo sokugoba, khona-ke ukwakheka kwesithombe akukwazi ukudwetshwa ngezindlela ezintathu njengoba kuboniswe esithombeni. Kungaba nezindlela ezimbili kuphela zokudweba ukwakheka kwesithombe. Sicela uqaphele isibonelo sokwakheka kwesithombe ngesibuko esiqondile, lapho ibanga lento kusuka ezibukweni eziqondile lihlukile, maqondana nokwakheka kwesithombe ngesibuko esiqondile.
