Constructor Detail

InteractiveView

public InteractiveView(java.awt.GraphicsConfiguration gc)

Interactive view displays 3 perpendicular planes used for interacting with the 3d scene.

Parameters:

gc - used for getting the best graphics configuration.

Method Detail

getComponent

public java.awt.Component getComponent()

Gets the component that this is being drawn on.]

Returns:

the datacanvas as an awt component for being added to a border layout.

addSnake

public void addSnake(Snake s)

Add a Snake by creating a poly linea polyline that is backed by the added snake.

Parameters:

s - snake that will be drawn on 3d section view

updateSnakePositions

public void updateSnakePositions()

The polylines are backed by a snake but their geometry is based on a different object so they need to be updated after the snake deforms.

deleteSnake

public void deleteSnake(Snake s)

deletes the chosen snake by removing it from the scene and from the list of stored snakes

Parameters:

s - the snake that will be removed

updateCursor

public void updateCursor(double x,
                         double y,
                         double z)

Recieves a coordinate in image space and coverts it to the scene space,moves the cursor to that location.

Parameters:

x - image or 'real' space coordinate.

y - image or 'real' space coordinate.

z - image or 'real' space coordinate.

followCursor

public void followCursor(double x,
                         double y,
                         double z)

During initialization this follows the cursor with a polyline

Parameters:

x - coordinate

y - coordinate

z - coordinate

updatePick

public void updatePick(com.sun.j3d.utils.picking.PickResult[] results,
                       java.awt.event.MouseEvent evt,
                       boolean clicked)

Use the PickResults to find the point on the plane that the pick result occured over. Returns the first plane encountered in array so the results should be sorted by closest to pick source.

Parameters:

results - sorted list of PickResults

evt - the moust event that generated the pick

clicked - if it was a click

reset

public void reset(SnakeBufferedImages sbi)

Resets the current display, clears all snakes, planes and bounding boxes resets the scale, creates new planes and bounding boxes then applies the threed texture

Parameters:

sbi - contains the dimensions and the volume texture

createTexCoordinteGeneration

public javax.media.j3d.TexCoordGeneration createTexCoordinteGeneration(float x,
                                                                       float y,

Uses the vectors x,y,z to scale the volume texture to the proper coordinates.

Parameters:

x - coordinate scaled to principle axis

y - coordinate scaled to principle axis

z - coordinate scaled to principle axis

Returns:

TextureCoordinate generation so that the slices can slice a volume texture.

updateDisplay
