- Courbe3D( <f(t)> [, divisions, discontinuities] )
- Description: draw a left curve parametrized by <f(t)> with $f\left(t\right)=[x\left(t\right)+iy\left(t\right),z\left(t\right]$ or $f(\left(t\right)=M\left(x\left(t\right),y\left(t\right),z\left(t\right)\right)$. The <divisions> number can be given by 2 between 2 consecutive points, and <discontinuités> (0 or 1) can be taken in count as in the function Courbe.
