  • Field Details

    • dy

      public double dy
      The y-translation.
  • Constructor Details

    • RenderingInfo

      public RenderingInfo(List<Face> faces, Point2D[] projPts, double dx, double dy)
      Creates a new instance.
      Parameters:
      faces - the rendered faces (in order of rendering).
      projPts - the projected points for all vertices in the 3D model.
      dx - the x-delta.
      dy - the y-delta.
  • Method Details

    • getFaces

      public List<Face> getFaces()
      Returns the list of faces rendered.
      Returns:
      The list of faces.
    • getProjectedPoints

      Returns the projected points.
      Returns:
      The projected points.
    • getDX

      public double getDX()
      Returns the x-translation amount. All projected points are centered on (0, 0) but the rendering to the screen (or other Graphics2D target) performs two translations: the first is to the center of the bounding rectangle, and the second is to apply the translate2D attribute of the chart. The result of these translations is stored here and used in the fetchObjectAt(x, y) method.
      Returns:
      The x-translation.
    • getDY

      public double getDY()
      Returns the y-translation amount.
      Returns:
      The y-translation.
    • addElement

      public void addElement(RenderedElement element)
      Adds a rendered element to the rendering info.
      Parameters:
      element - the element (null not permitted).
    • addOffsetElement

      public void addOffsetElement(RenderedElement element)
      Adds a rendered element to the list of offset elements.
      Parameters:
      element - the element (null not permitted).
    • fetchObjectAt

      public Object3D fetchObjectAt(double x, double y)
      Fetches the object, if any, that is rendered at (x, y).
      Parameters:
      x - the x-coordinate.
      y - the y-coordinate.
      Returns:
      The object (or null).
    • findElementAt

      public RenderedElement findElementAt(double x, double y)
      Finds the rendered element, if any, at the location (x, y). The method first calls fetchObjectAt(x, y) to see if there is an object at the specified location and, if there is, returns a new RenderedElement instance for that object. Otherwise, it searches the otherElements list to see if there is some other element (such as a title, legend, axis label or axis tick label) and returns that item. Finally, if no element is found, the method returns null.
      Parameters:
      x - the x-coordinate.
      y - the y-coordinate.
      Returns:
      The interactive element or null.
