Method Summary

Modifier and Type

Method

Description

Object

clone()

Provides a copy of this transformation.

double[]

direct(double[] point)

Transforms a given point

double[]

inverse(double[] point)

The inverse transformation (if it exists).

Method Details
- clone
  
  Object clone()
  
  Provides a copy of this transformation. This is used by an OSP 3D Element that will explicitely get a clone of it whenever its setTransformation() method is invoked. Thus, changing the original transformation directly has no effect unless a new setTransformation is invoked.
- direct
  
  double[] direct(double[] point)
  
  Transforms a given point
  
  Parameters:
  
  point - double[] the coordinates to be transformed (the array's contents will be changed accordingly)
  
  Returns:
  
  double[] the transformed vector (i.e. point)
- inverse
  
  double[] inverse(double[] point) throws UnsupportedOperationException
  
  The inverse transformation (if it exists). If the transformation is not invertible, then a call to this method must throw a UnsupportedOperationException exception.
  
  Parameters:
  
  point - double[] the coordinates to be transformed (the array's contents will be changed accordingly)
  
  Returns:
  
  double[] the transformed vector (i.e. point)
  
  Throws:
  
  UnsupportedOperationException - If the transformation is not invertible
