Constructor Detail

Rotation3D

public Rotation3D()

Create identity transformation.

Rotation3D

public Rotation3D(double e11,
          double e12,
          double e13,
          double e21,
          double e22,
          double e23,
          double e31,
          double e32,
          double e33)

Create rotation given the matrix elements. Multiplying a vector of coordinates by this matrix converts coordinates from transformed to original reference frame.

Rotation3D

public Rotation3D(Hep3Matrix matrix)

Create rotation given the matrix. Multiplying a vector of coordinates by this matrix converts coordinates from transformed to original reference frame.

Rotation3D

public Rotation3D(Axis axis,
          double angle)

Create transformation to a reference frame rotated by angle around axis.
