  • Method Details

    • getIdentity

      static StaticTransform getIdentity()
      Get the identity static transform. It overrides most methods for speed.
      Returns:
      identity transform.

    • transformPosition

      default Vector3D transformPosition(Vector3D position)
      Transform a position vector (including translation effects).
      Parameters:
      position - vector to transform
      Returns:
      transformed position

    • transformPosition

      default <T extends CalculusFieldElement<T>> FieldVector3D<T> transformPosition(FieldVector3D<T> position)
      Transform a position vector (including translation effects).
      Type Parameters:
      T - the type of the field elements
      Parameters:
      position - vector to transform
      Returns:
      transformed position

    • transformVector

      default Vector3D transformVector(Vector3D vector)
      Transform a vector (ignoring translation effects).
      Parameters:
      vector - vector to transform
      Returns:
      transformed vector

    • transformVector

      default <T extends CalculusFieldElement<T>> FieldVector3D<T> transformVector(FieldVector3D<T> vector)
      Transform a vector (ignoring translation effects).
      Type Parameters:
      T - the type of the field elements
      Parameters:
      vector - vector to transform
      Returns:
      transformed vector

    • transformLine

      default Line transformLine(Line line)
      Transform a line.
      Parameters:
      line - to transform
      Returns:
      transformed line

    • getTranslation

      Vector3D getTranslation()
      Get the underlying elementary translation.

      A transform can be uniquely represented as an elementary translation followed by an elementary rotation. This method returns this unique elementary translation.

      Returns:
      underlying elementary translation

    • getRotation

      Rotation getRotation()
      Get the underlying elementary rotation.

      A transform can be uniquely represented as an elementary translation followed by an elementary rotation. This method returns this unique elementary rotation.

      Returns:
      underlying elementary rotation

    • getInverse

      StaticTransform getInverse()
      Get the inverse transform of the instance.
      Returns:
      inverse transform of the instance

    • getStaticInverse

      default StaticTransform getStaticInverse()
      Get the inverse transform of the instance in static form (without rates). This enables to create a purely static inverse, as inheritors such as Transform may have a relatively computationally-heavy #getInverse() method.
      Returns:
      inverse static transform of the instance
      Since:
      12.1

    • compose

      static StaticTransform compose(AbsoluteDate date, StaticTransform first, StaticTransform second)
      Build a transform by combining two existing ones.

      Note that the dates of the two existing transformed are ignored, and the combined transform date is set to the date supplied in this constructor without any attempt to shift the raw transforms. This is a design choice allowing user full control of the combination.

      Parameters:
      date - date of the transform
      first - first transform applied
      second - second transform applied
      Returns:
      the newly created static transform that has the same effect as applying first, then second.

    • compositeTranslation

      static Vector3D compositeTranslation(StaticTransform first, StaticTransform second)
      Compute a composite translation.
      Parameters:
      first - first applied transform
      second - second applied transform
      Returns:
      translation part of the composite transform

    • compositeRotation

      static Rotation compositeRotation(StaticTransform first, StaticTransform second)
      Compute a composite rotation.
      Parameters:
      first - first applied transform
      second - second applied transform
      Returns:
      rotation part of the composite transform

    • of

      static StaticTransform of(AbsoluteDate date, Rotation rotation)
      Create a new static transform from a rotation and zero translation.
      Parameters:
      date - of translation.
      rotation - to apply after the translation. That is after translating applying this rotation produces positions expressed in the new frame.
      Returns:
      the newly created static transform.

    • of

      static StaticTransform of(AbsoluteDate date, Vector3D translation)
      Create a new static transform from a translation and rotation.
      Parameters:
      date - of translation.
      translation - to apply, expressed in the old frame. That is, the opposite of the coordinates of the new origin in the old frame.
      Returns:
      the newly created static transform.
