19.2.1 Grips hauv Polylines thiab Splines

Nyob rau hauv polylines multifunction grips yog ob hom: cov neeg uas tshwm sim ntawm lawv ib sab thiab cov uas tshwm sim rau hauv nruab nrab ntawm lawv qhov chaw. Lub vertex pinch cov kev xaiv cia ntxiv ntxiv thiab tshem tawm ib qho. Cov kev xaiv ntawm tus pinching ntawm lub midpoints cia ntxiv ib qho ntxiv thiab kuj hloov ua lub voj voog rau hauv nws cov lus rov qab. Yog tias nws yog ib txoj kab, tus tuav yuav muaj qhov kev hloov los hloov qhov ntawd ntu rau hauv ib qho arc; Yog hais tias nws yog ib qho arc, ces cov ntawv qhia zaub mov yuav muab qhov hloov ntawm nws mus rau hauv ib txoj kab ncaj nraim.

Nyob rau hauv cov ntaub ntawv ntawm lub splines, thawj qhov uas peb yuav tsum tau feem ntau yog tias ib tus ntawm lawv cov grips yog tiag tiag ib tug mus rau kev tswj ntawm tus spline, vim nws tso cai rau peb xaiv ntawm cov ntsiab lus ntawm kev hloov los yog tswj ib. Raws li koj yuav nco ntsoov, hauv seem uas peb kos splines peb tau hais tias cov ntsiab lus kev hloov nyob rau ntawm txoj hlua kabmob, thaum uas qhov kev tswj qhov kev txiav tawm tsis pom ib tus polygon uas nrhiav cov nplua. Nyob rau hauv ob qho tib si, cov ntawv qhia zaub mov ntawm cov kab ntawv multifunction pub peb txav, ntxiv los sis rho tawm cov ntsiab lus kev hloov lossis tswj ib qho.

19.2.2 Grips hauv kev tuag

Lwm hom khoom nrog ntau yam multifunction grips yog matrices. Cov tuav nyob rau hauv lub sab laug ces kaum tso cai rau koj kom tshem tau cov array raws li ib tug tag nrho (thiab, yog li ntawd, sau Kho kom raug neeg hom grips peb pom nyob rau hauv lub 19.1 seem), cov lwm yam, nyob ntawm seb lawv qhov chaw nyob, tso cai rau koj los mus hloov lub xov tooj los yog deb kab thiab txhua kab. Lub clamping ntawm lub kaum sab xis saum toj kawg nkaus pub koj hloov ob qho tib si tib lub sijhawm.
