Constructor Detail

DrawPanel

public DrawPanel(int drawboardsize,
                 java.awt.Image backbuffer,
                 java.awt.Graphics2D backg,
                 Parameter param)

Initializes the DrawPanel. Defines the drawing area, and constructs Points for later drawing the axes.

Parameters:

drawboardsize -

backbuffer - Representing the graphical image, or here, a area to draw in.

backg - Class for rendering 2D-shapes.

param - Contains all necessary parameters.

Method Detail

drawAgain

public void drawAgain(AbstractCrystal crystal)

For drawing a new lattice. This should be evoked, whenever the lattice changes. Then it starts a calculation of all lattice points.

Parameters:

crystal - The class representing the recent lattice.

drawWireframe

public void drawWireframe(java.awt.Graphics2D g)

Drawing the 3D-view. This function is responsible for calculating the coordinates, in dependence of azimuth and elevation, and drawing points and edges. It is therefore evoked, whenever the selected crystal is changed and whenever the mouse is used for dragging the picture.

Parameters:

g - Responsible for 2D-Drawings.
