Nimitz Cubic curve:

Start point $\mathrm{t}=0$ , end point $\mathrm{t}=1$

Tangent vector at start point $=P_{0}^{1}=\left[P_{2}-P_{0}\right]$

Tangent vector at end point $=P_{1}^{1}=\left[P_{3}-P_{1}\right]$

$P(t)=\sum_{i=0}^{3} C_{i} t^{i}$

$P(t)=C_{0}+C_{1} t+C_{2} t^{2}+C_{3} t^{3}$

$P^{1}(t)=C_{1}+2 C_{2} t+3 C_{3} t^{2}$

At $t=0$

$P_{0}=C_{0}$

$P_{0}^{1}=C_{1}$

At $t=1$

$P_{1}=C_{0}+C_{1}+C_{2}+C_{3} \ldots (1)$

$P_{1}^{1}=C_{1}+2 C_{2}+3 C_{3} \ldots (2)$

Multiplying eqn 1 by 3 and Subtracting by 2

$3 P_{1}-P_{1}^{1}=3 C_{0}+3 C_{1}+3 C_{2}+3 C_{3}-C_{1}-2 C_{2}-3 C_{3}$

$3 P_{1}-P_{1}^{1}=3 C_{0}+2 C_{1}+C_{2}$

$\therefore C_{2}=3 P_{1}-P_{1}^{1}-3 P_{0}-2 P_{0}^{1}$

Similarly,

$\therefore C_{3}=3 P_{1}-P_{1}^{1}-3 P_{0}-2 P_{0}^{1}$

$2 P_{1}-P_{1}^{1}=2 C_{0}+2 C_{1}+2 C_{2}+2 C_{3}-C_{1}-2 C_{2}-3 C_{3}$

$2 P_{1}-P_{1}^{1}=2 C_{0}+C_{1}-C_{3}$

$C_{3}=2 C_{0}+C_{1}-2 P_{1}+P_{1}^{1}$

$\begin{aligned} P(t) &=C_{0}+C_{1} t+C_{2} t^{2}+C_{3} t^{3} \\ P(t) &=P_{0}+P_{0}^{1} t+\left[3 P_{1}-P_{1}^{1}-3 P_{0}-2 P_{0}^{1}\right] t^{2}+\left[2 P_{0}+P_{0}^{1}-2 P_{1}+P_{1}^{1}\right] t^{3} \\ &=P_{0}\left[2 t^{3}-3 t^{2}+1\right]+P_{1}\left[-2 t^{3}+3 t^{2}\right]+P_{0}^{1}\left[t^{3}-2 t^{2}+t\right]+P_{1}^{1}\left[t^{3}-t^{2}\right] \end{aligned}$

$P(t)=\left[P_{0} P_{1} P_{0}^{1} P_{1}^{1}\right]^{}\left[\begin{array}{ccc}{2 t^{3}} & {-3 t^{2}} & {1} \\ {-2 t^{3}} & {3 t^{2}} & {1} \\ {t^{3}} & {-2 t^{2}} & {t} \\ {t^{3}} & {-t^{2}} & {1} \end{array}\right]$

$P(t)=\left[\begin{array}{cccc}{2} & {-3} & {0} & {1} \\ {-2} & {3} & {0} & {0} \\ {1} & {-2} & {1} & {0} \\ {1} & {-1} & {0} & {0}\end{array}\right]\left[\begin{array}{l}{t^{3}} \\ {t^{2}} \\ {t} \\ {1}\end{array}\right]$
