Parameters

ControlPoints

One-dimensional array of doubles (see Remarks)

Return Value

Control points determine the shape of a spline or curve. Starting with a set control points, all other points of a spline can be calculated. A given point on the spline is calculated using the polynomial basis functions of its nearest control points. The knot vector determines which control point basis functions are in force for calculating each point along a curve.

The size of the ControlPoints array is based on the curve dimension:

• if dimension = 2 then each Control Point has 2 doubles ( x and y coordinates )

• if dimension = 3 then each Control Point has 3 doubles ( x, y, and z coordinates)

• if dimension = 4 then each Control Point has 4 doubles ( x, y, and z coordinates, and w = weight )

Size of ControlPoints array = control points count X dimension
