3D qhov projection yog ib txoj hauv kev ntawm mappingthree-dimensional cov ntsiab lus rau ib lub dav hlau ob-dimensional. Duab qhov projection yog ib tug raws tu qauv, siv nyob rau hauv kev kos duab , los ntawm cov duab ntawm ib qho khoom peb-dimensional yog kwv yees mus rau ib tug planar nto yam tsis muaj kev pab ntawm numericalcalculation.
Yog li ntawd, qhov projection twg yog siv hauv engineering graphics?
Hauv engineering kev kos duab raws li plaub txoj kev ntawm qhov projection feem ntau siv , cov no yog: Isometric qhov projection . Oblique qhov projection . Kev xav qhov projection.
Ib yam li ntawd, qhov projection hom projection yog dab tsi? Orthographic Qhov projection Hauv orthographic qhov projection kev taw qhia ntawm qhov projection yog ib txwm rau cov qhov projection ntawm lub dav hlau. Muaj peb hom ntawm orthographic kev kwv yees - Pem hauv ntej Qhov projection . Sab saum toj Qhov projection . Sab Qhov projection.
Kuj tseem paub yog, qhov projection hauv computer graphics yog dab tsi?
Qhov projection . Nws yog tus txheej txheem ntawm kev hloov 3Dobject rau hauv 2D khoom. Nws kuj txhais tau tias yog daim ntawv qhia lossis hloov pauv ntawm cov khoom hauv qhov projection dav hlau los yog dav hlau saib. Lub dav hlau saib yog tso tawm nto.
Dab tsi yog 3 lub dav hlau ntawm qhov projection?
Feem ntau, peb views ntawm ib yam khoom yog npaj. Cov no yog Sab saum toj Saib, Pem Hauv Ntej Saib, thiab Sab Saib. Yog tias dav hlau yog khaws cia nyob rau hauv ib txoj hauj lwm ntsug, ces nws yog hu ua ntsug dav hlau . Yog tias dav hlau yog khaws cia rau hauv txoj hauj lwm kab rov tav, ces nws yog hu ua kab rov tav dav hlau.
Pom zoo:
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov zoo thiab qhov tsis zoo ntawm Mercator projection yog dab tsi?
Disadvantages: Mercator projection distorts qhov loj ntawm cov khoom raws li lub latitude nce los ntawm Equator mus rau tus ncej, qhov twg lub teev yuav infinite. Yog li, piv txwv li, Greenland thiab Antarctica tshwm sim ntau dua qhov txheeb ze rau thaj av loj nyob ze ntawm txoj kab nruab nrab tshaj li qhov lawv muaj tiag
Kev pom kev pom hauv computer graphics yog dab tsi?
Kev pom kev pom yog qhov pom ntawm daim duab peb sab uas qhia qhov siab, qhov dav, thiab qhov tob rau cov duab tiag tiag lossis duab
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Qhov projection thiab hom projection yog dab tsi?
Cov nram qab no yog cov hom rau kev kwv yees: Ib qho Point (ib qho tseem ceeb ntawm qhov chaw ploj mus) Ob Lub ntsiab lus (ob lub ntsiab lus tseem ceeb) Peb taw tes (Peb lub ntsiab lus Vanishing point) Cavalier txee Multi saib Axonometric Isometric DimetricTrimetric Projections Parallel ProjectionsPerspective Projections Orthographic (
