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.) | |

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 PoNode.) | |
RayPick | (Inherited from SoNode.) | |
Search | (Inherited from PoNode.) | |
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. | |
SetSynchronizable | Sets this to be a ScaleViz synchronizable object. | |
SetToDefaults | Sets all fields in this object to their default values. | |
ToString |
Converts this SoBase structure to a human readable string.
(Inherited from SoBase.) | |
Touch | Marks an instance as modified, simulating a change to it. | |
Write | (Inherited from PoNode.) |
Name | Description | |
---|---|---|
ColorMapping | Sets pointer to a callback function which computes a color from a real value. | |
IsDisposable | ISafeDisposable interface implementation.
(Inherited from SoDisposable.) | |

TransparencyMapping | Sets pointer to a callback function which computes a transparency from a real value. | |
transparencyValueDeletedParts | Each primitive part of which transparency >= transparencyValueDeletedParts, is deleted. | |
UserData |
Gets or sets the user data to be contained by the field container.
(Inherited from SoFieldContainer.) |
This node defines the current data mapping for all subsequent MeshViz representations which use it. There is no data mapping until a OIV.MeshViz.Nodes.PoDataMapping node is traversed.
This node defines a non linear association between colors, transparencies and floating-point values. In other words, this association is defined by 2 functions F(c,v) and F(c,t):
F(c,v)(V) = C (with c being a color and v being a value). F(t,v)(V) = T (with t being a transparency and v being a value).F(c,v) and F(t,v) are given by the user. If they are not given by the user, default one are used. The default F(c,v) computes a linear data mapping between black and white. The default F(c,t) returns always 0.
