doDraw3D

protected void doDraw3D(java.awt.Graphics2D g,
                        View3D view,
                        Transform3D transform)

Description copied from class: Exhibit3D

Draws this Exhibit in a 3D view. The method in the Exhibit3D class does nothing. Subclasses should override this method to do the actual drawing. When this method is called, Exhibit3D.computeDrawData3D(View3D, boolean, Transform3D, Transform3D) has already been called, so that any cached data should be correct. Note that this method is called only if the Exhibit is being drawn in a View3D. Exhibits that have both two and three dimensional renderings should also override Exhibit.doDraw(Graphics2D, View, Transform).

When drawing a 3D exhibit, you are strongly advised to use the drawing routines supplied by the View3D and View3DLit classes. These routines will automatically produce the correct results in stereo views -- the same is not true about direct drawing to the graphics context.

Overrides:

doDraw3D in class LatticeModel

Parameters:

g - the graphics context where the exhibit is being drawn.

view - The View3D in which the exhibit is being drawn. In general, it is advisable to use the view for all drawing operations.

transform - The transform that is being used to draw the exhibit.

getDefaultView

public View getDefaultView()

Description copied from class: Exhibit3D

Returns the default View of this Exhibit. In the Exhibit3D class, the return value is a basic View3D.

Overrides:

getDefaultView in class LatticeModel
