Kev sib tw yog lub tswvyim uas ua rau lub peev xwm ntawm ib yam khoom lossis hom khoom lag luam kom dhau tus analogues hauv cov xwm txheej tam sim no. Cov ntaub ntawv hais txog qhov ntsuas no pab tsim txoj hauv kev muaj tseeb ntawm qhov thov ntawm cov khoom.
Cov ntaub ntawv no pab txhawb rau kev rov tshwm sim cov lus qhia rau kev txhim kho kev lag luam txuas ntxiv thiab qhov tsim ntawm kev npaj txhij rau kev hloov. Qhov tom kawg yog qhov tseem ceeb tshaj plaws rau kev hloov kho sai rau cov xwm txheej tshiab. Cov ua lag luam, cov neeg siv khoom, cov tsim tawm, lub xeev siv ntau txoj hauv kev los ntsuas kev sib tw. Lawm, txhua qhov kev kawm ua qhov kev tshawb xyuas raws li tau txais txiaj ntsig hauv kev lag luam niaj hnub no. Piv txwv li, cov tub ua lag luam, txhawm rau xaiv cov khoom siv peev, txheeb xyuas qhov txheeb ze ntawm thaj chaw nyiam ntawm thaj chaw lossis cov chaw lag luam tshwj xeeb. Kev ua tiav ntawm kev nqis peev uas twb tau ua dhau los tseem coj mus rau hauv tus lej. Cov hau kev rau kev txheeb xyuas qib ntawm kev sib tw yuav tsum xav txog cov yam ntxwv ua tau zoo ntawm cov khoom lag luam, tus nqi sib piv nrog analogues, qib kev pabcuam ntawm cov neeg siv khoom lag luam, qhov ua tau zoo ntawm cov kev tshaj tawm siv thev naus laus zis.
Dab tsi muaj kev sib tw polygon suav nrog
Xws li txoj kev ntsuas kev sib piv yog nkag siab heev thiab pab piv cov khoom muag, kev pabcuam thiab cov lag luam nrog txhua lwm yam. Txhawm rau ua qhov no, cov duab kos qhia cov haujlwm ntawm cov khoom sib piv rau txhua qhov ntsuas. Ib lub polygon yog tsim nyob rau hauv lub hauv paus ntawm ntau cov yam ntxwv, uas yog sawv cev hauv daim duab los ntawm cov vectors txuas ntxiv los ntawm ib qho taw tes hauv cov lus qhia sib txawv. Ntawm lawv yog cov hauv qab no:
- Tus nqi ntawm ib qho kev pabcuam lossis khoom lag luam;
- Cov ntsiab lus tseem ceeb ntawm cov khoom / kev pabcuam;
- Qib ntawm kev tsim nyog ntawm cov neeg ua haujlwm hauv kev muag;
- Kev pabcuam (kev xa tawm, sib dhos, lav thiab kho);
- Qhov ntim ntawm cov khoom lag luam muag (khw muag khoom npe, khw muag khoom);
- Lub nyiaj txiag zoo rau lub lag luam;
- Cov kev paub ntawm cov tuam txhab lossis cov kev paub tshiab ntawm cov khoom;
- Qib ntawm cov xwm txheej ntawm cov neeg siv khoom lag luam (muaj koj tus kheej lub vev xaib, kev tshaj tawm tswv yim).
Lawm, cov ntsiab lus saum toj no tsuas yog kwv yees tus nqi rau cov axes, txij li txhua yam khoom lossis kev pabcuam nws muaj nws tus yam ntxwv.
Cov nuances tseem ceeb hauv kev tsim cov kev sib tw
Tom qab tsim lub axes thiab txiav txim siab lawv qhov tseem ceeb siv cov txheej txheem ntsuas, qhov chaw ntawm cov khoom lag luam lossis cov chaw lag luam nyob ntawm lawv tau txiav txim siab. Txhawm rau tsim polygon, koj yuav tsum ua tib zoo txuas cov ntsiab lus - ntsuas. Tom qab ntsuas xyuas cov nuj nqis tau, nws muaj peev xwm kos ib qho lus xaus txog qhov zoo thiab qhov tsis zoo ntawm cov khoom tau soj ntsuam. Tom qab ntawd muaj ib qho kev ua haujlwm sib txuas ntawm cov yam ntxwv zoo thiab kev ua haujlwm nquag pib tshem tawm cov kev cais tawm uas tau pom hauv chav kawm ntawm kev sib piv.
