Constructor Detail

DisplayMethod

public DisplayMethod(ChipCanvas parent)

Creates a new instance of DisplayMethod

Parameters:

parent - the containing ChipCanvas

Method Detail

setupGL

public javax.media.opengl.GL setupGL(javax.media.opengl.GLAutoDrawable drawable)

This utility method sets up the gl context for rendering. It is called at the the start of most of the DisplayMethods. It scales x,y,z in chip pixels (address by 1 increments), and sets the origin to the lower left corner of the screen with coordinates increase upwards and to right.

Parameters:

drawable - the drawable passed in.

Returns:

the context to draw in.

display

public abstract void display(javax.media.opengl.GLAutoDrawable drawable)

subclasses implmeent this display method to actually render. Typically they also call GL gl=setupGL(drawable) right after entry.

Parameters:

drawable - the GL context

getDescription

public java.lang.String getDescription()

getMenuItem

public javax.swing.JMenuItem getMenuItem()

setMenuItem

public void setMenuItem(javax.swing.JMenuItem menuItem)

getRenderer

public Chip2DRenderer getRenderer()

setRenderer

public void setRenderer(Chip2DRenderer renderer)

getAnnotators

public java.util.ArrayList<FrameAnnotater> getAnnotators()

setAnnotators

public void setAnnotators(java.util.ArrayList<FrameAnnotater> annotators)

addAnnotator

public void addAnnotator(FrameAnnotater annotator)

add an annotator to the drawn canvas. This is one way to annotate the drawn data; the other way is to annotate the histogram frame data.

Parameters:

annotator - the object that will annotate the frame data

removeAnnotator

public void removeAnnotator(FrameAnnotater annotator)

removes an annotator to the drawn canvas.

Parameters:

annotator - the object that will annotate the displayed data

removeAllAnnotators

public void removeAllAnnotators()

removes all annotators
