Use a linear fractional transformation to reparameterize the NURBS curve. This does not change the curve's domain.

Public Function Reparameterize ( 
	c As Double
) As Boolean

c

Type: System.Double
reparameterization constant (generally speaking, c should be > 0). The control points and knots are adjusted so that output_nurbs(t) = input_nurbs(lambda(t)), where lambda(t) = c*t/( (c-1)*t + 1 ). Note that lambda(0) = 0, lambda(1) = 1, lambda'(t) > 0, lambda'(0) = c and lambda'(1) = 1/c.

Type: Boolean
true if successful.

The cv and knot values are values are changed so that output_nurbs(t) = input_nurbs(lambda(t)).
