AverageLocalRefere nceFrame (Geometry1D)

Description

Get the average normal of given 1D geometry

Scripting Syntax

    Geometry1D.AverageLocalReferenceFrame( compIdxArray, XAxis, XAxisValid, YAxis, YAxisValid, ZAxis, ZAxisValid )

Parameters

Parameter | Type | Description
compIdxArray | Array of Integer values | An array of indices of 1D geometry Possible Values: • 0 <= compIdxArray(i) < Number of 1D geometry: Each index in the array must be valid
XAxis [in/out] | SIVector3 | Upon return, contains the X axis of the average local reference frame of the given 1D geometry
XAxisValid [in/out] | Boolean | Upon return, contains TRUE if the X axis of the reference frame is valid, else FALSE
YAxis [in/out] | SIVector3 | Upon return, contains the Y axis of the average local reference frame of the given 1D geometry
YAxisValid [in/out] | Boolean | Upon return, contains TRUE if the Y axis of the reference frame is valid, else FALSE
ZAxis [in/out] | SIVector3 | Upon return, contains the Z axis of the average local reference frame of the given 1D geometry
ZAxisValid [in/out] | Boolean | Upon return, contains TRUE if the Z axis of the reference frame is valid, else FALSE

VBScript Example

    'Create a cube
    CreatePrim "Cube", "MeshSurface"
    set oSelList = GetValue("SelectionList")
    set oItem = oSelList(0)
    set oGeometry = oItem.obj
    oNb1D = oGeometry.Nb1D
    set o1DGeometry = oGeometry.Geometry1D
    set oXAxis = XSIMath.CreateVector3()
    set oYAxis = XSIMath.CreateVector3()
    set oZAxis = XSIMath.CreateVector3()
    ' Construct an array containing the indices 0,1,2,3
    dim oIndicesArray
    oIndicesArray = Array( 0, 1, 2, 3 )
    o1DGeometry.AverageLocalReferenceFrame oIndicesArray, oXAxis, oXAxisValid, oYAxis, oYAxisValid, oZAxis, oZAxisValid
    if oXAxisValid then
    LogMessage "Component (0, 1, 2, 3) average X axis : " & oXAxis.x & " | " & oXAxis.y & " | " & oXAxis.z
    else
    LogMessage "Component (0, 1, 2, 3) INVALID average X axis"

    else
    LogMessage "Component (0, 1, 2, 3) INVALID average Y axis"
    end if
    if oZAxisValid then
