Explaining NURBS is beyond the scope of this documentation. If you are unfamiliar with the principles of representing smooth curves and surfaces when doing 3D visualization, we recommend finding a good book on the subject.

Constructor. |
|
Destructor. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoShape. |
|
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoShape. |
|
Calculates picked point based on primitives generated by subclasses. Reimplemented from SoShape. |
|
Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables. Reimplemented from SoShape. |
|
Redefined to notify open caches that this shape contains lines. Reimplemented from SoShape. |
|
This method is part of the original SGI Inventor API, but not implemented in Coin, as it looks like a method that should probably have been private in Open Inventor. |
|
For internal use only. Reimplemented from SoShape. |
|
Calculates the bounding box of all control points, and sets the center to the average of these points. Reimplemented from SoShape. |
|
Overloaded to return NULL. Reimplemented from SoShape. |
|
Number of control points for this curve. |
|
The control point indices. Supply at least numControlPoint indices. |
|
The knot vector. |
