popp (computer graphics)

3dee computer graphics mein, popping ack avaanchhaniya drishya prabhaav koo sandarbhit kartaa haye joe taba hotaa haye jaba ack 3dee vastu kaa ack alag poorv-ganana star (laude) mein sankraman darshak key liye achaanak aur spasht hotaa haye. lauding algorithm ack 3dee object kii jyaamitiya jatilata koo cumm kartaa haye aur darshak seey aage jaataa haye aur vaha guma hui jatilata koo lautaata haye kyonki darshak 3dee object key karib hoe jaataa haye, jisase yeh "popp" hoe jaataa haye kyonki yeh achaanak adhik vistrit hoe jaataa haye. lauding algorithm darshak seey doori kii tulanaa mein adhik karakon parr nirbhar curr sakate hain, lekin yeh aksar praathamik kaarak hotaa haye jise maanaa jaataa haye. jaba madhyavarti charanon key binaa seedhe vibhinn laude key beach switch kiya jaataa haye tou popping sabse spasht hoti haye. bhoo-aakriti aur laude sammishran jaisi takneeken parivartan koo adhik kramik banaakar drishya popp koo kaafee cumm curr sakati hain.
mishran karein.
alfa sammishran key roop mein bhee jaanaa jaataa haye, yaa alfa sanyojan iss takneek koo ack saath 3 dee model key donon laude koo pradarshit karke aur ack chhoti see sankraman avadhi mein unhein ack saath milakar popping koo cumm curr detaa haye.
mishran prakriya key dauran pratyek laude key liye ack alfa moolya nirdisht kiya jaataa haye, joe vastuon kii paardarshita nirdhaarit kartaa haye. sankraman kii shuruat mein, praarambhik laude kaa alfa moolya 1 (poori tarah seey apaardarshi) hoga aur nae laude kaa alfa moolya 0.0 (poori tarah seey pardarshi) hoga. jaise hii darshak 3dee object key paas jaataa haye aur usa doori taka pahunch jaataa haye jaba laude parivartan samanya roop seey hotaa haye, laude alfa maan dheere-dheere taba taka badal jaate hain jaba taka kii nae laude kaa alfa moolya 1 naheen hoe jaataa haye, jiss bindu parr praarambhik laude abb prastut naheen kiya jaayega.
yeh jore denaa mahatvapurna haye kii laude mishran kewal usa doori parr hotaa haye joe ack laude samanya roop seey badalati haye aur kewal ack chhoti doori parr. isaliye yadi ack anukaran key dauran laude parivartan doori kii 100 ikaaiyon parr hoga tou laude mishran prakriya doori kii 95 ikaaiyon seey shuru hogi aur doori kii 105 ikaaiyon seey poori hogi.
laude sammishran key dou pramukh nuksan hain. yeh computing shakti key mamle mein mahanga haye kyonki donon laude ack saath prastut kiye jaate hain taaki mishran hoe sakey aur pratiutpaadak hoe sakate hain kyonki lauding algorithm kaa upayog karane kaa kaaran drishyon koo prastut karane key kharch koo cumm karna haye. takneek taba prabhaavi naheen hoti haye jaba darshak 3dee object key karib hotaa haye kyonki mishran prakriya spasht roop seey spasht hogi aur isake parinamswarup bhoot dikhaai dega.
bhoo-aakriti.
bhoo-aakriti ack aisee takneek haye joe ack sucharu sankraman banaane key liye dou laude key beach madhyavarti charanon key roop mein kaam karane key liye 3 dee model key anumaanon koo jodkar laude parivartanon key dauran popp koo cumm karati haye. iss vidhi kaa upayog karke 3dee model koo sanshodhit karane key liye praathamik sanchaalan kinare key dhahane (sheershon koo hataana) aur sheersh vibhajan (sheershon koo jodana) hain.
paaramparik bhoo-aakriti dou laude key beach 3dee model kaa ack anukram banaata haye. ack baar shuru honey key baad anukram koo baadhit naheen kiya jaa sakata haye aur jaba taka laude parivartan puuraa naheen hoe jaataa, taba taka isamen koee sanshodhan naheen kiya jaa sakata haye. iss pratibandh key kaaran, paaramparik bhoo-aakriti paraspar anukaran key liye upayukt naheen haye kyonki yadi paristhitiyaan apratyaashit roop seey badalati hain tou prakriya koo jaldi seey ulat naheen kiya jaa sakata haye.
vaastavik samay bhoo-aakriti seedhe 3 dee model key vyaktigat sheershon koo isake sthaan koo samaayojit karane key liye sanshodhit karati haye. yeh kissy bhee frame key dauran bhoo-aakriti mein kiye gaye parivartanon koo yaa tou chala rahey rupankanon koo rokane yaa 3 dee model key aage key rupankanon koo shuru karane kii anumati detaa haye. choonki kaee sheershon koo ack dusare key swatantra roop seey rupaantarit karane key liye trigger kiya jaa sakata haye, isaliye kuchh sheershon koo asthaayi roop seey bund karane kii aavashyakta hoti haye taaki yeh sunishchit kiya jaa sakey kii ack sucharu sankraman hotaa haye, jisake parinamswarup vilambit parivartan hoe sakata haye. vaastavik samay key bhoo-aakriti kaa lachilaapan ise paraspar anukaran key liye ack prabhaavi samadhan banaata haye.
