Thawj lub kaum sab xis projection yog ib txoj hauv kev tsim a2D kos duab ntawm 3D khoom. Nws yog siv nyob rau hauv cov teb chaws Europe thiab Asia thiab tsis tau officially siv nyob rau hauv Australia tau ntau xyoo. Hauv Australia, peb lub kaum sab xis projection yog txoj kev nyiam ntawm orthographic qhov projection . Nco ntsoov lub cim rau xub orthographic qhov projection.
Hauv qhov no, thawj lub kaum sab xis projection yog dab tsi?
Cov ' thawj lub kaum sab xis ' moniker hais txog txoj kev thedrawing yog nteg tawm, as opposed to thib peb lub kaum sab xis . Txoj kev yooj yim tshaj kom pom thawj lub kaum sab xis projection yog xav txog tias koj muaj ib lub tais pem hauv ntej ntawm koj. Muab qhov koj xav kos rau hauv qab ntawm lub tais.
Ib tug kuj nug, vim li cas peb thiaj siv 1st lub kaum sab xis projection? Ua ntej ntawm tag nrho, peb siv thawj lub kaum sab xis thiab peb lub kaum sab xis projection vim tias nws xav tias Horizontalplane yog tig CLOCKWISE coj lawv mus rau tib lub dav hlau (fordrawing lub hom phiaj) thiab yog tias peb siv thib ob lossis plaub angle projection , ces Kab rov tav thiab ntsug views yuav overlap, tsim kev tsis meej pem hauv lawv
Ib yam li ntawd, nws tau nug, qhov txawv ntawm 1st thiab 3rd lub kaum sab xis yog dab tsi?
Kom tau txais cov thawj lub kaum sab xis projection , qhov khoom tso hauv thawj quadrant lub ntsiab lus nws tau muab tso rau nruab nrab lub dav hlau ntawm qhov projection thiab tus neeg soj ntsuam. Forthe peb lub kaum sab xis projection , cov khoom yog muab tso rau hauv qab thiab qab ntawm lub dav hlau saib lub ntsiab lus ntawm lub dav hlau qhov projection yog nruab nrab tus soj ntsuam thiab cov khoom.
Qhov twg yog 1st angle projection siv?
Kev piav qhia: Tus neeg soj ntsuam ib txwm nyob ntawm sab xis sab kawg. Yog li thaum tus soj ntsuam saib cov khoom los ua ntej thiab tom qab ntawd qhov projection dav hlau raws li cov khoom nyob rau hauv lub 1st quadrant hauv 1st lub kaum sab xis projection.

Dab tsi yog qhov tsis zoo ntawm Robinson projection?
Robinson projections tsis sib npaug; lawv raug kev txom nyem los ntawm compression. Txawm li cas los xij, tus nqi ntawm cheeb tsam distortion feem ntau tsawg hauv li 45 ° ntawm kab zauv. Conformality: Lub Robinson projection tsis conformal; cov duab yog distorted ntau tshaj li lawv yuav nyob rau hauv ib tug tiag tiag conformal projection
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
Thawj lub kaum sab xis orthographic projection yog dab tsi?
Thawj lub kaum sab xis projection yog ib txoj hauv kev tsim a2D kos duab ntawm 3D khoom. Nws yog tsuas yog siv nyob rau hauv cov teb chaws Europe thiab Asia thiab tsis tau officially siv nyob rau hauv teb chaws Australia tau ntau xyoo.In Australia, peb lub kaum sab xis projection yog qhov kev xaiv ntawm orthographic projection. Nco ntsoov lub cim rau firstangle orthographic projection
Dab tsi yog qhov projection hauv engineering graphics?
3D projection yog ib txoj hauv kev ntawm kev kos peb-dimensional cov ntsiab lus rau lub dav hlau ob sab. Graphicalprojection yog ib tug raws tu qauv, siv nyob rau hauv kev kos duab, los ntawm uas ib tug duab ntawm ib tug peb-dimensional khoom yog projectedon rau ib tug planar nto yam tsis muaj kev pab ntawm numericalcalculation
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 (
