The parametric eqn for a cubic Bezier is, from PLRM:
|
|
r(t) = at^3 + bt^2 + ct + r0
|
|
with the control points:
|
|
r1 = r0 + c/3
|
|
r2 = r1 + (c + b)/3
|
|
r3 = r0 + c + b + a
|
|
|
|
A quadratic Beizer has the form:
|
|
p(t) = (1-t)^2 p0 + 2(1-t)t p1 + t^2 p2
|
|
|
|
So equating powers of t leads to:
|
|
r1 = 2/3 p1 + 1/3 p0
|
|
r2 = 2/3 p1 + 1/3 p2
|
|
and of course r0 = p0, r3 = p2
