GTTransformUtils (Xj3D 2.3-nps Code Library)

java.lang.Object

org.web3d.vrml.renderer.common.geospatial.GTTransformUtils

public class GTTransformUtils extends Object

Utility class to create a GeoTools2 transformation class for a given geoSystem field definition.

This class runs as a singleton to allow for caching of internal fetched transformation routines.

Method Details
- getInstance
  
  public static GTTransformUtils getInstance() throws org.opengis.referencing.FactoryException
  
  Fetch the singleton instance of the factory. If needed, a new instance will be created.
  
  Returns:
  
  The shared singleton instance of this class
  
  Throws:
  
  org.opengis.referencing.FactoryException - There was a problem creating the class
- createSystemTransform
  
  public org.opengis.referencing.operation.MathTransform createSystemTransform(String[] systemDef, boolean[] coordSwap) throws org.opengis.referencing.FactoryException
  
  From the given system definition strings, generate a coordinate transformation service.
  Check whether we need to reverse the two primary coordinate systems. If true, then the user needs to swap the coordinate values for X and Y.
  
  Parameters:
  
  systemDef - The X3D system definition string
  
  coordSwap - an array of length 1 for returning the primary coordinate swap flag
  
  Returns:
  
  A transform for taking geo coordinates to cartesian
  
  Throws:
  
  org.opengis.referencing.FactoryException
