SyntaxThe PoLinearDataMapping type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PoLinearDataMapping | Constructor. |
Methods| Name | Description | |
|---|---|---|
| AffectsState | Returns true if a node has an effect on the state during traversal. |
| Callback | (Inherited from PoNode.) |
| 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 PoNodeDoAction(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 | (Inherited from PoNode.) |
| GetColor(Single) | Returns the color associated to a value. |
| GetColor(Single, Single) | Returns the color and transparency associated to a value. |
| 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 PoNode.) |
| GetName | Returns the name of an instance. |
| GetPrimitiveCount | (Inherited from PoNode.) |
| GetRenderEngineMode | Returns the supported Render engine mode. |
| GetRenderUnitID | (Inherited from SoNode.) |
| GetStringName | (Inherited from SoBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |

| HandleEvent | (Inherited from PoNode.) |
| 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.) |
Properties| Name | Description | |

| transparency1 | Defines the first transparency of the linear data mapping. |
| transparency2 | Defines the second transparency of the linear data mapping. |
| transparencyEnabled | Enable/Disable the taking into account of transparency. |
| transparencyValueDeletedParts | Each primitive part of which transparency >= transparencyValueDeletedParts, is deleted. |
| UserData |

| value1 | Defines the first value of the linear data mapping. |
| value2 | Defines the second value of the linear data mapping. |
RemarksThis 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 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 linear, so only two values (value1 and value2), two associated transparencies (transparency1,transparency2) and two associated colors (color1 and color2) define these functions. For a given value vi, its color ci is determined by linear interpolation between (value1,color1) and (value2,color2). Idem for the transparencies.FILE FORMAT/DEFAULT
