magarengBezier

magarengBezier(a, b, c, d, t)

magarengBezier(a, b, c, d, t) e go bolelela gore ntlha e e fa gare ga konego ya Bezier e kae. Dipalo tse nne tsa ntlha ke dikhoutinete tsa dintlha tse nne, ka tatelano e thalaBezier e di batlang ka yona. Palo ya botlhano, t, ke gore o le kae mo tseleng: 0 ke tshimologo, 1 ke bokhutlo, mme 0.5 ke fa gare.

E dira mokwalo o le mongwe ka nako. Naya dikhoutinete tsa x mme o busediwa x; naya tsa y mme o busediwa y. Ka jalo o e bitsa gabedi.

Leina le tswa mo magareng. Se se diragalang ke go batla boleng jo bo fa gare — jaaka magareng e batla palo e e fa gare ga tse pedi, mme magarengMmala e batla mmala o o fa gare ga mebala e mebedi. magarengBezier e batla e e fa gare mo tseleng e e menaganeng go na le mo mothalong o o tlhamaletseng.

⚠ Ga e thibele t. O ka solofela palo e e magareng ga 0 le 1, mme ga go na se se e thibelang: magarengBezier(0, 0, 100, 100, 2) e busa −400. Se se lekantswe. Fa o batla go e thibela, dirisa thibela.

Diparamethara

Leina	Mofuta	Tlhaloso
a	palo	Khoutinete ya ntlha ya bofelo ya ntlha.
b	palo	Khoutinete ya ntlha ya taolo ya ntlha.
c	palo	Khoutinete ya ntlha ya taolo ya bobedi.
d	palo	Khoutinete ya ntlha ya bofelo ya bobedi.
t	palo	Gore o le kae mo tseleng, magareng ga 0 le 1.
