Mumakombiyuta mafirimu , apo mufanisi anopedzisa kuvaka chimiro, iyo inonzi 3D mesh mesh, inenge yakafanana nemifananidzo yemarble. (Uye kana iwe wakamboedza kuisa nekukurisa mifananidzo ye marble, zvichida unoziva kuti inopera zvisingabviri).
Pamberi pehutungamiri hwemutambo weD 3D unokwanisa kuendeswa kune boka rezvipikisi, rinofanira kunge rakasungwa kune imwe nzira yezvibatanidza nekugadzirisa zvigadziro kuitira kuti zvipikisi zvigone kuisa mufananidzo. Iyi nzira inowanzopedzwa nevanyori vanozivikanwa sehutungamiri vevatungamiri vezvekambani (TDs) kana riggers.
Unhu TDs hushanda pamwe chete nevatadzi kuti vaone kuti nyaya ipi neipi yehutano inofanirwa, asi basa ravo rokutakura nderokutora static 3D mesh uye inoita kuti rive rakagadzirira mifananidzo-chirongwa chinonzi rigging.
Rigging
Chimiro chetsika chinonyanya chidimbu chemajeri chakasungirirwa ku 3D mesh. Kungofanana nemapfupa chaiwo, kugadzika kunoumbwa nemajofu nemapfupa, chimwe nechimwe chinoshanda se "kubata" izvo zvipenyu zvinogona kushandisa kukotamisa chimiro mune zvayo zvinoda.
Chimiro chetsika chinogona kubva kubva nyore uye chinoshamisa kuti chigadzikane chakaoma. Chigadziriro chekutanga chekuita nyore chingavakwa mumaawa mashomanana, nepo ruzivo rwakanyatsorongedzerwa rwefirimu ringave ruchida mazuva kana vhiki vasati vatenzi vakagadzirira mapikicha ePiarar-level.
Kuisa Skeleton
Kuiswa kwemafupa ndiyo inenge iri chikamu chakareruka chekugadzira. Pamusoro pezvikamu zvizhinji, majoini anofanirwa kuiswa chaiwo kwavanenge vari mune imwe nyika-skeleton, ine imwe kana maviri kunze.
- Utungamiri Hwokubatana: Kuti rive rakagadzikana kushanda zvakanaka, mapfupa nemajoini anofanira kutevera hurumende yepamusoro. Pakugadzirisa skeleton yomuitiro, yekutanga yejoka iwe inonzi inonzi midzi . Zvose zvinotevera zvinosanganiswa nemudzi iwoyo zvakananga, kana kuti zvisina kukodzera kuburikidza nedzimwe sangano.
- Pamberi Kinematics: Kumbomira mberi (FK) imwe yenzira mbiri dzinokosha yekuverenga musangano wekubatanidzwa wehutano hwakakwana. Paunenge uchishandisa FK rigging, hupi hupi hupi hupi hupi hunogona hunochinja humwe humwe skeleton hunowa pasi payo pahutungamiri huri pamwe chete.
- Semuenzaniso, kutenderera kwefudzi remufudzi kunoshandura nzvimbo yeheta, wrist, uye ruoko. Kana uchifambidzana nekunyorera zvinyorwa, munyori wacho anowanzofanira kugadzirisa kushandura uye nzvimbo yehuni imwe neimwe-kuti iite zvinodiwa apo mhuka inoshandiswa inoshanda kuburikidza nehutano hwakagadzirwa sequentially: midzi → musana wechipfuva → bhokisi → gorofu → nezvimwe. chibatanidzwa chinopedzisira (seminondo) chinoratidzirwa sechishanda chengirove dzakabatanidzwa dzejojo dzose pamusoro payo muhurumende.
Inverse Kinematics
IK kukanganisa ndiyo nzira inoshandiswa kubva kune dzimwe nyika uye inowanzoshandiswa sarudzo yakakwana yekugadzira maoko nemakumbo omunhu. Nechirongwa cheK, sangano rinogumisa rinonyatsoiswa neanoritator, asi majoi ari pamusoro apa pahurumende anongorondedzerwa ne software.
IK yakanyatsokodzera apo mifananidzo inoda kuti chibatanidzo chinopedzisira kuiswa zvakanyatsonaka & $ 151; munhu anokwira makera muenzaniso wakanaka. Nemhaka yokuti maoko etsoka nemakumbo zvinogona kuiswa zvakananga pamakumbo emakirani pane kuti mutevedzeri achinje maitiro ake akabatanidzwa-pamwe-a-joint, kIg inogadzirisa inogona kuita kuti hupenyu huve hwakawanda kwazvo. Chimwe chinokanganisa ndechekuti nokuti maK animation anoshandisa interpolation yepurogiramu, pane kazhinji kese basa rekuchenesa rinofanira kuitwa kuti ripedze kupfura.
Degrees of Freedom / Constraints
Paunenge uchibvarura, chengetedza mupfungwa kuti unobatanidza semakumbo nemabvi zvakagumira kune imwe yero yerusununguko munyika chaiye, zvinoreva kuti vanogona kungonamatira pamwe chete. Saizvozvowo, mutsipa wevanhu haugoni kuchinja zvizere madigiri 360. Kuti ubatsire kudzivisa zvifananidzo zvisingaitiki, chinhu chakanakisisa chekugadzirisa matanho akabatana paunenge uchivaka iwe. Tichakurukura izvi zvakare muchidzidzo.
Squash uye Tsika
Chimwe chiyeuchidzo chinofanirwa kuitwa ndechekuti kugadzika kuchasimbisa squash uye kutambanudza, kana kuti unhu huchagadziriswa kuti hurumidze kufamba. Squash uye kutambanudza inzira inokosha mukunyanyisa kwekaroto cartoon animation , asi kazhinji haisi kutarisa zvakanaka mune zvechokwadi mafirimu / VFX basa. Kana iwe uchida kuti urongwa hwako hurambe hwakachengetedza zvakakwana, zvakakosha kuisa chinetso chekuvhara chinzvimbo chekubatanidza kwega kwega zvichienderana nezvose zvakasara.
Kutarisa Kwiso
Nzira yehutano hwemunhu kazhinji inoparadzaniswa zvachose kubva pamasimba ekudzidzira kufamba. Hazvina kukodzera uye zvinoshamisa zvakaoma kuita gurusa rinogutsa rekushandisa uchishandiswa mutsika / pfupa romufuro, naizvozvo marph targets (kana kuti maumbirwo maitiro) anowanzoonekwa semhinduro inoshanda. Kudzora pameso kune musoro uye pachako, saka ngwarira nyaya inotsvaga nyaya yacho zvakadzama.
