static double angleBetween(PVector v1, PVector v2)

Gets the angle between the two vectors in the XY plane.

Parameters

• v1 - the first vector
• v2 - the second vector

Returns

The angle between the two vectors, in degrees.

Example

    PVector v1 = new PVector(0, 1, 0);
    PVector v2 = new PVector(1, 0, 0);
    double angle = PVector.angleBetween(v1, v2);
    // angle is 90
