SyntaxThe SoNurbsProperty type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SoNurbsProperty | Constructor. |
Methods| Name | Description | |
|---|---|---|
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Overrides SoNodeCallback(SoCallbackAction).) |
| Copy | Calls Copy(false). (Inherited from SoNode.) |
| Copy(Boolean) | Creates and returns an exact copy of the node. |
| CopyFieldValues(SoFieldContainer) | Calls CopyFieldValues(fc, false). (Inherited from SoFieldContainer.) |
| CopyFieldValues(SoFieldContainer, Boolean) | Copies the contents of fc's fields into this object's fields. |
| Dispose |
Releases all resources used by SoDisposable.
(Inherited from SoDisposable.) |
| Distribute | (Inherited from SoNode.) |
| DoAction | (Overrides SoNodeDoAction(SoAction).) |
| EnableNotify | Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| FieldsAreEqual | Returns true if this object's fields are exactly equal to fc's fields. |
| Get | Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. |
| GetAllFields | Returns a list of fields, including the eventIn's and eventOut's. |
| GetAlternateRep | This method is called by actions to allow the node to provide an "alternate representation" when appropriate (typically depending on the action type). |
| GetBoundingBox | (Overrides SoNodeGetBoundingBox(SoGetBoundingBoxAction).) |
| GetEventIn | Returns a the eventIn with the given name. |
| GetEventOut | Returns the eventOut with the given name. |
| GetField | Returns a the field of this object whose name is fieldName. |
| GetFieldName | Returns the name of the given field in the fieldName argument. |
| GetFields | Appends references to all of this object's fields to resultList, and returns the number of fields appended. |
| GetHashCode |
Overrides GetHashCode().
(Inherited from SoNetBase.) |
| GetMatrix | (Inherited from SoNode.) |
| GetName | Returns the name of an instance. |

| HasDefaultValues | Returns true if all of the object's fields have their default values. |
| IsBoundingBoxIgnoring | This method is used by getBoundingBox action traversal to know if the current node must be traversed or not, ie the bounding should be ignored. |
| IsNotifyEnabled | Notification is the process of telling interested objects that this object has changed. |
| IsOverride | Returns the state of the override flag. |
| IsSynchronizable | Gets the ScaleViz synchronizable state of this object. |
| Pick | (Inherited from SoNode.) |
| RayPick | (Overrides SoNodeRayPick(SoRayPickAction).) |
| Search | (Inherited from SoNode.) |
| Set | Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. |
| SetName | (Inherited from SoBase.) |
| SetOverride | Turns the override flag on or off. |

| tessellationType | Specifies the tessellation type. |
| UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
RemarksThis node defines an additional set of properties used by OIV.Inventor.Nodes.SoNurbsSurface when rendering NURBS surfaces.
For a large NURBS surface, it is sometimes more effective to display two central isoparametric curves rather than facet boundaries (as in wireframe mode) because the latter may provide an overly complicated view of the surface.
This node allows you to specify the NURBS draw style; the color of the trim curves, boundaries and isoparametric curves; the line pattern of the isoparametric curves; the number of sample points between trim curves control points; the type of tessellation; angle and distance for adaptive tessellation.
The NURBS draw style is a bitmask specifying which combination of the following representations to use for displaying the NURBS: normal display, trim curves and boundaries, and/or central isoparametric curves.
Turning off the normal NURBS surface display, and turning on the display of trim curves, boundaries and isoparametric curves can dramatically speed up rendering of large models.
When in ADAPTIVE tessellation mode, regions with a low curvature will be less tessellated than regions with a high curvature.
