IGetUVBounds Method (IFace2)

Gets the values that describe the U, V bounds of this face.

.NET Syntax

Visual Basic (Declaration) 
Function IGetUVBounds() As Double
Visual Basic (Usage) 
Dim instance As IFace2
Dim value As Double
 
value = instance.IGetUVBounds()
C# 
double IGetUVBounds()
C++/CLI 
double IGetUVBounds(); 

Return Value

  • in-process, unmanaged C++: Pointer to an array of doubles (see Remarks
  • VBA, VB.NET, C#, and C++/CLI: Not supported
  • See In-process Methods for details about this type of method.

    Remarks

    The return values bound an area of the surface in which the face is defined. You can determine the surface U, V bounds using ISurface::Parameterization or ISurface::IParameterization.

    The returned data is an array of 4 doubles arranged in the following order:

    retval[0] - Minimum U parameter of this face

    retval[1] - Maximum U parameter of this face

    retval[2] - Minimum V parameter of this face

    retval[3] - Maximum V parameter of this face

    The minimum parameters are always less than the maximum parameters, and the range (for example, retval[1] - retval[0] and retval[3]-retval[2]) is always less than or equal to the U and V range of the underlying surface.

    For surfaces with periodic parameters, the face parameter box can never be larger than the period of the corresponding surface parameter.

    uRange[0] <= retval[0] < uRange[1]

    vRange[0] <= retval[2] < vRange[1] 

    where uRange and vRange describe the UV range of the surface

    Therefore, a face that straddles the boundary of a periodic parameter has an upper parameter value for the face that is greater than the upper parameter range of the surface.
