Convert java to vb.net (short)

This project is to convert this function from Java to vb.net. It has some code that I don't understand. such as "scale" and "add" etc. Here is the JAVA function. ( I am still working on the other code so it is not testable, please be sure you know java and vb well enough to do this without testing) public static Point C(double t, int order, int nPoints, Point points[], double weights[], double knots[]) { Point c = new Point(); double rational = 0; for (int counter = 0; counter < nPoints; counter++) { double b = B(counter, order, t, knots); Point p = points[counter].scale(b * weights[counter]); [login to view URL](p); rational += b * weights[counter]; } return [login to view URL](1.0 / rational); } I will have some other projects in a few hours later.
