ReverseEvaluate Method (IFace2)

Gets the UV parameters for the given XYZ location on this face.

.NET Syntax

Visual Basic (Declaration) 
Function ReverseEvaluate( _
   ByVal PositionX As Double, _
   ByVal PositionY As Double, _
   ByVal PositionZ As Double _
) As Object
Visual Basic (Usage) 
Dim instance As IFace2
Dim PositionX As Double
Dim PositionY As Double
Dim PositionZ As Double
Dim value As Object
 
value = instance.ReverseEvaluate(PositionX, PositionY, PositionZ)
C# 
object ReverseEvaluate( 
   double PositionX,
   double PositionY,
   double PositionZ
)
C++/CLI 
Object^ ReverseEvaluate( 
&   double PositionX,
&   double PositionY,
&   double PositionZ
) 

Parameters

PositionX
X coordinate of this location on the face
PositionY
Y coordinate of this location on the face
PositionZ
Z coordinate of this location on the face

Return Value

Array of two doubles representing the U and V parameters of this location on the face

Example

Remarks

This method returns corrected UV parameters for periodic surfaces; thus, you should use this method when dealing with periodic surfaces.

For example, you can have a cylindrical surface that extends from 0 to 2pi in the Udir. The face related to this surface in some cases extends from 0 to pi, then from 0 to pi again. In this case, neither ISurface::IReverseEvaluate nor ISurface::ReverseEvaluate will work for values greater than pi (the returned U value will be greater than Maximum U for the face). However, IFace2::IReverseEvaluate, and IFace2::ReverseEvaluate, will return return the correct values.
