TickNeeded()

bool TickNeeded ( int  currentLevel, float  currentAngle  )

protected

Determines if a tick with the given angle should be drawn or not. If a higher priority scale already has a tick at that level and deconfliction is enabled, then this method will return false.

Parameters

currentLevel	The current tick type being considered for drawing.
currentAngle	The angle of the proposed tick.

Returns

True if the tick should be drawn.

UpdateBoundingVolume()

virtual void UpdateBoundingVolume ( )

virtual

Updates the bounding volume of this object This method should be called if the vertices change for picking and culling to work correctly. This will only update this object. If PerformGroupCullCheck is enabled for one of the objects parents, you may also need to call CalculateParentBoundingBox() to update all of the objects parents.

Reimplemented from DisplayObject.

UseScalableLines() [1/2]

bool UseScalableLines ( )

inline

Gets the drawing mode for this scale

Returns

The drawing mode for this scale

UseScalableLines() [2/2]

void UseScalableLines

(

const bool &

val

)

Sets the drawing mode for this scale

Parameters

val	New drawing mode

Vertices()

virtual Vertex * Vertices ( )

virtual

Gets the object's vertices. You should call UpdateBoundingVolume after changing an object's extents.

Returns

Pointer to the object's vertex array
