Class Vector3Dd


  • public class Vector3Dd
    extends java.lang.Object
    A 3D vector \mathbf{v}\in \mathbb{R}^3

    \robabx{i}{j}{\mathbf{v}} = \left[ \begin{array}{c} v_x \\ v_y \\ v_z \end{array} \right]

    Usage example:

    const Vector3D v1(1.0, 2.0, 3.0); const Vector3D v2(6.0, 7.0, 8.0); const Vector3D v3 = cross(v1, v2); const double d = dot(v1, v2); const Vector3D v4 = v2 - v1;
