Method Detail

computeOrientationVector

protected Vec4 computeOrientationVector(DrawContext dc,
                                        Vec4 point,
                                        Vec4 normal,
                                        Angle heading,
                                        Angle pitch)

Compute a direction vector given a point, heading and pitch.

Parameters:

dc - current draw context

point - point at which to compute direction vector

normal - surface normal at point

heading - desired heading

pitch - desired pitch

Returns:

A vector pointing in the direction of the desired heading and pitch

createDisplayList

protected int[] createDisplayList(DrawContext dc,
                                  double radius)

dispose

public void dispose()

Description copied from interface: Disposable

Disposes of any internal resources allocated by the object.

Specified by:

dispose in interface Disposable

doRender

protected abstract void doRender(DrawContext dc,
                                 Marker marker,
                                 Vec4 point,
                                 double radius,
                                 int[] dlResource)

drawShape

protected abstract int drawShape(DrawContext dc,
                                 double radius)

getName

public String getName()

getShapeType

public String getShapeType()

Specified by:

getShapeType in interface MarkerShape

initialize

protected void initialize(DrawContext dc)

isApplyOrientation

public boolean isApplyOrientation()

Indicates whether or not the shape applies heading, pitch, and roll when it draws itself. Even if this field is true, the shape may not apply all of the rotations.

Returns:

true if orientation is applied to the rendered shape, false if not.

render

public void render(DrawContext dc,
                   Marker marker,
                   Vec4 point,
                   double radius)

Specified by:

render in interface MarkerShape

render

public void render(DrawContext dc,
                   Marker marker,
                   Vec4 point,
                   double radius,
                   boolean isRelative)

Specified by:

render in interface MarkerShape

setApplyOrientation

public void setApplyOrientation(boolean applyOrientation)

Specifies whether or not the shape applies heading, pitch, and roll when it renders.

Parameters:

applyOrientation - true if the shape must apply heading, pitch, and roll (if they are supported by the shape), false if it the shape must not apply this orientation.
