Constructor Detail

Canvas3D

public Canvas3D()

Creates a standard 3D canvas, with mouse interactions enabled

Method Detail

getArcBall

public ArcBall getArcBall()

Returns:

the ArcBall

add

public void add(DrawableProvider provider)

Adds a drawable provider to the list

Specified by:

add in interface DrawableHandler

remove

public void remove(DrawableProvider provider)

removes a drawable procvider from the list

Specified by:

remove in interface DrawableHandler

repaint

public void repaint()

Delegates to draw. This method is to be called when a User repaint has to be made. Since we use the BackedPanel, a System repaint will just copy the buffered image

draw

public void draw()

Applies the current ArcBall matrix to the model matrix and iterates over all the drawable providers.

drawObjects

protected void drawObjects(VectorGraphics g,
                           Enumeration e)

Iterates over al drawable providers and calls drawObject on them

drawObject

protected void drawObject(VectorGraphics g,
                          Object obj)

Draws/handles a single object. Currently there is support for:

• Color
• Polyline3
• Matrix
• Ortho
• Frustum
• Scale

setBounds

public void setBounds(int x,
                      int y,
                      int width,
                      int height)

Changes the bounds of the window

Overrides:

setBounds in class BackedPanel
