SyntaxThe PoNonLinearDataMapping2 type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PoNonLinearDataMapping2 | 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). |

| 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.) |

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 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).
There are two ways to express F(c,v)(V):F(c,v)(V) is non linear, but linear per level, so a list of values sorted in increasing order and a list of colors associated define this function. Thus, the association is (V1,C1), (V2,C2),...,(Vn,Cn) with V1 < V2 <...< Vn. For a given value vi, Vk <= vi <= Vk+1, the associated color ci is determined by a linear interpolation between (Vk,Ck) and (Vk+1,Ck+1).
F(c,v)(V) is defined by level, so a list of n values sorted in increasing order and a list of n+1 colors associated define this function. Thus, the association is C1, (V1,C2), (V2,C3),...,(Vn,Cn+1) with V1 < V2 <...< Vn. For a given value vi, Vk <= vi < Vk+1, the associated color ci is Ck+1. If vi < V1, the associated color ci is C1. In the two methods, the list of values is sorted in increasing order (and the associated colors also).
There are as well, two ways to express F(t,v)(V)
