## ControlPointCollection.Array

### Description

Returns an Array of control points for this NURBS component. Depending on the geometry type of the 3D object, the returned array will be either 2- or 3-dimensional:
If the component is a NurbsCurve, a 2D array of [X,Y,Z,W] values is returned. If the component is a NurbsSurface, a 3D array is returned.
Note: The indexing to access an array element is different depending on the language you use due to the fact that C++ arrays are arranged in memory differently than safearrays.
- C++: [U] [V] [X,Y,Z,W]
- Scripting: [X,Y,Z,W] [V] [U]
In order for the memory mapping to be consistent between C++ and scripting, the safearray indexing is always the reverse of the C++ indexing, as shown above.

### C# Syntax

    // get accessor

    Object rtn = ControlPointCollection.Array;

    // set accessor

    ControlPointCollection.Array = Object;

### Examples

#### VBScript Example

    set oObject = ActiveSceneRoot.AddGeometry("Sphere","NurbsSurface")

    set oNurbsSurfaceMesh = oObject.ActivePrimitive.Geometry

    set oControlPoints = oNurbsSurfaceMesh.Surfaces(0).ControlPoints

    aControlPoints = oControlPoints.Array

    for i = lbound( aControlPoints, 1 ) to ubound( aControlPoints, 1 )

    	for j = lbound( aControlPoints, 2 ) to ubound( aControlPoints, 2 )

    		LogMessage aControlPoints(i,j,0)

    		LogMessage aControlPoints(i,j,1)

    		LogMessage aControlPoints(i,j,2)

    		LogMessage aControlPoints(i,j,3)

    	next

    next
