Field Detail

dx

public double dx

Per-frame screen offset indicating this symbol's x-offset relative to the screenPoint. Calculated each frame in AbstractTacticalSymbol.computeTransform(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially 0.

dy

public double dy

Per-frame screen offset indicating this symbol's y-offset relative to the screenPoint. Calculated each frame in AbstractTacticalSymbol.computeTransform(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially 0.

eyeDistance

public double eyeDistance

Per-frame distance corresponding to the distance between the placePoint and the View's eye point. Used to order the symbol as an ordered renderable, and is returned by getDistanceFromEye. Calculated each frame in AbstractTacticalSymbol.computeSymbolPoints(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially 0.

iconRectScaled

public Rectangle iconRectScaled

iconRect with scaling applied, used to lay out text.

layoutRect

public Rectangle layoutRect

layoutRectScaled

public Rectangle layoutRectScaled

layoutRect with scaling applied, used to lay out text.

placePoint

public Vec4 placePoint

Per-frame Cartesian point corresponding to this symbol's position. Calculated each frame in AbstractTacticalSymbol.computeSymbolPoints(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially null.

screenPoint

public Vec4 screenPoint

Per-frame screen point corresponding to the projection of the placePoint in the viewport (on the screen). Calculated each frame in AbstractTacticalSymbol.computeSymbolPoints(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially null.

screenRect

public Rectangle screenRect

sx

public double sx

Per-frame screen scale indicating this symbol's x-scale relative to the screen offset. Calculated each frame in AbstractTacticalSymbol.computeTransform(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially 0.

sy

public double sy

Per-frame screen scale indicating this symbol's y-scale relative to the screen offset. Calculated each frame in AbstractTacticalSymbol.computeTransform(gov.nasa.worldwind.render.DrawContext, gov.nasa.worldwind.symbology.AbstractTacticalSymbol.OrderedSymbol). Initially 0.

Method Detail

doDrawOrderedRenderable

protected void doDrawOrderedRenderable(DrawContext dc,
                                       PickSupport pickCandidates)

getDistanceFromEye

public double getDistanceFromEye()

Description copied from interface: OrderedRenderable

Returns the ordered renderable's distance from the current view's eye point. Intended to be used only to sort a list of ordered renderables according to eye distance, and only during frame generation when a view is active.

Specified by:

getDistanceFromEye in interface OrderedRenderable

Returns:

the distance of the ordered renderable from the current view's eye point.

getPickLayer

public Layer getPickLayer()

isEnableBatchPicking

public boolean isEnableBatchPicking()

isEnableBatchRendering

public boolean isEnableBatchRendering()

pick

public void pick(DrawContext dc,
                 Point pickPoint)

Description copied from interface: OrderedRenderable

Executes a pick of the ordered renderable.

Specified by:

pick in interface OrderedRenderable

Parameters:

dc - the current draw context.

pickPoint - the pick point.

render

public void render(DrawContext dc)

Description copied from interface: Renderable

Causes this Renderable to render itself using the provided draw context.

Specified by:

render in interface Renderable

Parameters:

dc - the DrawContext to be used
