Thawj thiab kawg cov ntsiab lus cim qhov pib thiab qhov kawg ntawm txoj kev, thaum cov ntsiab lus nruab nrab txhais tau hais tias txoj kev scurvature.

Ntawm no, dab tsi yog txhais los ntawm Bezier nkhaus?

A Bezier nkhaus yog lej txhais nkhaus siv nyob rau hauv ob-dimensional graphic daim ntaub ntawv. Cov nkhaus yog txhais los ntawm plaub lub ntsiab lus: thawj qhov chaw thiab qhov kawg ntawm txoj haujlwm (uas yog hu ua "anchors") thiab ob lub ntsiab lus nruab nrab (uas yog hu ua "kho").

Hais txog qhov no, lub luag haujlwm ntawm Bezier yog dab tsi?

Hauv vector graphics, Bézier curves yog siv los ua qauv du curves uas tuaj yeem scaled indefinitely. "Paths", asthey feem ntau raug xa mus rau hauv cov duab manipulation programs, yog kev sib txuas ntawm kev sib txuas Bézier nkhaus. Txoj kev tsis raug txwv los ntawm kev txwv ntawm rasterized dluab thiab yog intuitive tomodify.

Bezier nkhaus ua haujlwm li cas?
