Please can you tell me how I can draw 4th order bezier curve in Geogebra?
I have these polynomial cubics
B0(t) = (1 - t)3,
B1(t) = 3t(1 - t)2,
B2(t) = 3t2(1 - t),
B3(t) = t3
but with these I can draw only simple Bezier curve and I need 4th order bezier curve with 5 control points.
If you have endpoints
A
,E
and control pointsB
,C
,D
, you can create the 4th degree Bézier curve using this GeoGebra command:You can get the polynomials by multiplying the binomial coefficients with corresponding powers of
t
and(1-t)
, see explicit definition of Bézier curve on Wikipedia for details.
