Method Summary

void	annotate(float[][][] frame) annotate the RGB frame somehow by color pixels in the rendered pixel frame data.
void	annotate(javax.media.opengl.GLAutoDrawable drawable) Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active).
void	annotate(java.awt.Graphics2D g) each annotator is called by the relevant class (e.g.
EventPacket<?>	filterPacket(EventPacket<?> in) Subclasses implement this method to define custom processing.
java.lang.Object	getFilterState() should return the filter state in some useful form
int	getPacketBufferSize()
void	initFilter() this should allocate and initialize memory: it may be called when the chip e.g.
void	resetFilter() should reset the filter to initial state
void	setFilterEnabled(boolean yes) Overrides to avoid setting preferences for the enclosed filters

public BallShooterCochlea(AEChip chip)

Method Detail

filterPacket

public EventPacket<?> filterPacket(EventPacket<?> in)

Description copied from class: EventFilter2D

Subclasses implement this method to define custom processing.

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packet

Returns:

the output packet

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter

getFilterState

public java.lang.Object getFilterState()

Description copied from class: EventFilter

should return the filter state in some useful form

Specified by:

getFilterState in class EventFilter

setFilterEnabled

public void setFilterEnabled(boolean yes)

Overrides to avoid setting preferences for the enclosed filters

Overrides:

setFilterEnabled in class EventFilter2D

Parameters:

yes - true to reset

See Also:

EventFilter.setPreferredEnabledState()

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

annotate

public void annotate(javax.media.opengl.GLAutoDrawable drawable)

Description copied from interface: FrameAnnotater

Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). The FrameAnnotater then can use JOGL calls to render to the screen by getting the GL context, e.g. the following code, used in the context of an AEChip object, draws a golden lines from LL to UR of the pixel array.

        GL gl = drawable.getGL();
        gl.glBegin(GL.GL_LINES);
        gl.glColor3f(.5f, .5f, 0);
        gl.glVertex2f(0, 0);
        gl.glVertex2f(getSizeX() - 1, getSizeY() - 1);
        gl.glEnd();
 

Specified by:

annotate in interface FrameAnnotater

Parameters:

drawable - the OpenGL drawable components, e.g., GLCanvas

annotate

public void annotate(java.awt.Graphics2D g)

Description copied from interface: FrameAnnotater

each annotator is called by the relevant class (e.g. EyeTracker) and enters annotate with graphics context current, in coordinates with pixel 0,0 in UL corner and pixel spacing 1 unit before scaling transform (which is already active).

Specified by:

annotate in interface FrameAnnotater

Parameters:

g - the Graphics2D context

annotate

public void annotate(float[][][] frame)

Description copied from interface: FrameAnnotater

annotate the RGB frame somehow by color pixels in the rendered pixel frame data.

Specified by:

annotate in interface FrameAnnotater

Parameters:

frame - the RGB pixel information. First dimension is Y, second is X, third is RGB

getPacketBufferSize

public int getPacketBufferSize()

setPacketBufferSize

public void setPacketBufferSize(int packetBufferSize)
