First, we construct the one-level-of-de-Casteljau-up points:
|
||||
|
||||
\[
|
||||
\left \{ \begin{align}
|
||||
\left \{ \begin{aligned}
|
||||
v1 &= A' + \frac{e1 - A'}{t} \\
|
||||
v2 &= A' + \frac{e2 - A'}{1 - t}
|
||||
\end{align} \right .
|
||||
\end{aligned} \right .
|
||||
\]
|
||||
|
||||
And then we can compute the new control points:
|
||||
|
||||
\[
|
||||
\left \{ \begin{align}
|
||||
\left \{ \begin{aligned}
|
||||
C1' &= v1 + \frac{v1 - start}{t} \\
|
||||
C2' &= v2 + \frac{v2 - end}{1 - t}
|
||||
\end{align} \right .
|
||||
\end{aligned} \right .
|
||||
\]
|
||||
|
||||
And that's cubic curve manipulation.
