Title: JPanelGeodesic

Description: Geodesic drawing interface. Drawing the Geodesic curve on the surfaces. Depending on the type of surface displayed: either the SurfaceRender or the FlythruRenderer.

This file also includes the interface for cutting the mesh along the geodesic curve. The mesh can be cut along an open curve (which replaces the original mesh in the scene graph) or the mesh can be cut along a closed curve (which replaces the original mesh with two or more new meshes in the scene graph.

The interface for drawing geodesics with a "livewire" interface. When livewire mode is selected, by checking the "Livewire Mode" checkbox, then when the user selects points along the geodesic curve with the mouse, the Dijkstra's version of the geodesic is calculated and displayed as the mouse moves.

The user may display the geodesic in one of three ways: (1) the smoothed geodesic curve, which is based on a re-triangulation of the surface along Dijkstra's path and a smoothed version of Dijkstra's path. (2) Dijkstra's path along the original mesh vertices and triangle edges. (3) The straight-line distance between points -- Euclidian distance. Of the three display modes the Euclidian path is the only path *NOT* constrained to lie on the surface of the triangle mesh.

Distances for all three path types, for the total path lenths and the most recent point-pairs are displayed in the interface as well.

    frameHeight - int height
  - setDijkstra
```
public void setDijkstra(float fValue)
```
    Displays the Geodesic (dijkstra's along the mesh) distance between the last two points picked in the Geodesic class, as well as the running total for the current curve.
    
    Parameters:
    
    fValue - dijkstra's current value.
  - setEnabled
```
public void setEnabled(boolean flag)
```
    Since geodesic line only apply to the texture render surface, all the buttons are enabled only if the suface vector size is greater than 0. The method is called from the surfacePanel when add or remove surfaces.
    
    Overrides:
    
    setEnabled in class javax.swing.JComponent
    
    Parameters:
    
    flag - boolean
  - setEuclidian
```
public void setEuclidian(float fValue)
```
    Displays the Euclidian distance between the last two points picked in the Geodesic class, as well as the running total for the current curve.
    
    Parameters:
    
    fValue - current Eclidian value.
  - setFlythruRender
```
public void setFlythruRender(FlythruRender _flythruRender)
```
    Set the flythru render reference.
    
    Parameters:
    
    _flythruRender - FlythruRender
  - setGeodesicSmooth
```
public void setGeodesicSmooth(float fValue)
```
    Displays the Geodesic (smoothed) distance between the last two points picked in the Geodesic class, as well as the running total for the current curve.
    
    Parameters:
    
    fValue - the current geodesic smooth value.
  - toggleLivewire
```
public void toggleLivewire()
```
    Toggles between live wire mode and point and click mode for drawing geodesics on the surfaces. When live wire is active, then the use clicks to add the first point in a curve and then moves the mouse to see Dijkstra's path drawn between that point and the Mesh vertex that is nearest the mouse. When the user clicks again the point is drawn, and the displaay is between the last point clicked and the current mouse point.
  - togglePathDisplay
```
public void togglePathDisplay(int which)
```
    Causes the Geodesic class to switch between displaying the Smoothed Geodesic, Dijkst'ra path along the mesh, or the straight-line Euclidian path between the selected endpoints. Both the Geodesic and Dijkstr'a paths are constrained to lie on the surface of the mesh, whereas the straight-line distance may penetrate the mesh or be through space.
    
    Parameters:
    
    which - path index.
  - toggleWireframe
```
public void toggleWireframe()
```
    Toggles between wireframe and filled polygon drawing for the surfaces. Useful for testing the Geodesic curves:
  - finalize
```
protected void finalize()
                 throws java.lang.Throwable
```
    Calls disposeLocal.
    
    Overrides:
    
    finalize in class JPanelRendererBase
    
    Throws:
    
    java.lang.Throwable - DOCUMENT ME!
  - clearAllCuts
```
private void clearAllCuts()
```
    Undoes all cuts and replaces the cut mesh with the original mesh.
  - clearLastCut
```
private void clearLastCut()
```
    Undoes the last cut operation.
  - cutGeodesic
```
private void cutGeodesic()
```
    Calls the Geodesic cut function to cut the triangle mesh along the geodesic curves.
