Tus txheej txheem ua haujlwm ntawm kab rov tav ntsia hlau ntsia hlau sib xyaw yog: Cov khoom sib xyaw yog nruab nrog ob txoj haujlwm sib hloov thiab thim rov qab padd ntsia hlau sib tw. Duav ntsia hlau ya davhlau pib sib sau rau hauv qee qib, noj thiab nplawm cov khoom siv raws axis kev taw qhia thiab radial kev taw qhia, thiaj li mus sib xyaw cov ntaub ntawv tusyees hauv kev nrawm heev. Kab rov tav ribbon ntsia hlau sib xyaw cov yam ntxwv thiab kev ua tau zoo yog tias qhov nrawm nrawm los ntawm lub zog hloov tig nrog ntsia hlau ntsia hlau thiab ruaj khov ntawm cov ntsia hlau ntsia hlau ntsia hlau yuav ua kom tsis muaj zog. Nrog rau tsis muaj lub ntiajteb txawj nqus, muaj nyob sib txawv ntawm qhov loj me ntawm cov ntawv loj, cov tuab tuab, thiab lwm yam. Lub zog khaus lub zog yuav luv rau lub sijhawm sib tov rau ib pob, nws yuav ntau nrawm dua thiab ua haujlwm tau zoo dua. Txawm hais tias cov ntaub ntawv muaj qhov sib txawv ntawm qhov ntau thiab qhov loj me, nrog kev sib hloov thiab ceev nrawm ntawm kev npaj staggered lub duav ntsia hlau dav hlau, peb kuj tuaj yeem tau txais cov khoom sib xyaw zoo dua. Kab rov tav ribbon ntsia hlau tov khoom muaj cov sib sau ua ke siab, me me seem seem thiab tsim nyog rau kev sib xyaw ntau tshaj ob hom chiv thiab cov khoom ntxiv tom qab.
