# nurbssurface nrbss

Creates a nurbs surface.

Creates nurbs surface in a specified location from the specified points. It detects a best-fitting plane so it can be used to arbitrarily oriented surfaces.

nurbssurface (0 0 0) (50 50 0) 10 10 (0 0 0) (5 2 0) (5 5 0) (2 5 0) (2 2 2) (4 5 6) (7 8 9)
Creates nurbs surface from the specified points starting at point (0 0 0) and ending at point (50 50 0). Grid points are set 10 in x-direction and 10 in y-direction.

Text | Continuity | |

"c0" | Continuity | Only geometric continuity |

"g1" | Continuity | For each point on the curve, the tangent vectors "on the right" and "on the left" are co-linear with the same orientation |

"c1" | Continuity | Continuity of the first derivative. The "c1" curve is also "g1" but, in addition, the tangent vectors "on the right" and "on the left" are equal |

"g2" | Continuity | For each point on the curve, the normalized normal vectors "on the right" and "on the left" are equal |

"c2" | Continuity | Continuity of the second derivative. The "c2" curve is also "g2" but, in addition, the main directions of the curves also match. |

"c3" | Continuity | Continuity of the third derivative |
