Kev hloov pauv affine yog ib hom kev hloov pauv geometric geometric hloov pauv Hauv kev lej, kev hloov pauv geometric yog txhua qhov kev hloov pauv ntawm qhov teeb tsa rau nws tus kheej(los yog lwm qhov teeb tsa) nrog qee qhov tseem ceeb geometrical underpinning. Tshwj xeeb tshaj yog, nws yog ib txoj haujlwm uas nws lub npe thiab ntau yam yog cov ntsiab lus - feem ntau ob qho tib si los yog ob qho tib si. - xws li cov kev ua haujlwm yog txhaj tshuaj kom nws rov muaj nyob. https://en.wikipedia.org › wiki › Geometric_transformation
Geometric transformation - Wikipedia
uas khaws cia kev sib koom ua ke (yog tias sau cov ntsiab lus zaum ntawm kab ua ntej kev hloov pauv, lawv txhua tus zaum ntawm kab tom qab) thiab qhov sib piv ntawm qhov kev ncua deb ntawm cov ntsiab lus ntawm kab.
Koj txhais li cas affine transformation?
Ib qho kev hloov pauv yog kev hloov pauv uas khaws cia sib koom ua ke(piv txwv li, tag nrho cov ntsiab lus dag ntawm ib kab pib tseem nyob ntawm kab tom qab hloov pauv) thiab qhov sib piv ntawm qhov deb (piv txwv li, qhov midpoint ntawm ib kab ntu tseem yog qhov nruab nrab tom qab hloov pauv).
Dab tsi yog kev hloov pauv hloov pauv?
Ib qho kev hloov pauv tsis yog ib qho uas cov kab sib txuas hauv qhov chaw tsis tau khaws cia tom qab kev hloov pauv(xws li kev xav pom) lossis cov ntsiab lus nruab nrab ntawm kab tsis tau khaws cia (rau piv txwv tsis yog linear scaling raws ib axis).
Qhov txawv ntawm affine thiab projective transformation yog dab tsi?
Qhov sib txawv ntawm ob qhov kev hloov pauv no yog nyob rau hauv kab kawg ntawm kev hloov pauv matrix…. Txawm li cas los xij tsis zoo li qhov projective transformation, nws khaws kev sib luag.
Puas yog kev hloov pauv hloov pauv ib qho kev hloov pauv?
Ib qho kev hloov pauv qhia pom yuav ua li cas cov khoom pom tau hloov pauv raws li tus neeg soj ntsuam qhov kev xav hloov Cov kev hloov pauv no tso cai rau kev tsim kev pom kev cuam tshuam. Affine transformations yog siv rau scaling, skewing thiab rotation. Graphics Mill txhawb nqa ob chav kawm ntawm kev hloov pauv.
