Detailed Description

This class performs all rendering tasks.

Member Function Documentation

void vanetsim.gui.Renderer.drawMovingObjects ( Graphics2D g2d )

inline

This function renders all non-static objects on the supplied Graphics2D object.

Parameters

g2d	the `Graphics2D` object on which rendering takes place

void vanetsim.gui.Renderer.drawScale ( BufferedImage image )

inline

Creates an image to see the current scale.

Parameters

image the BufferedImage on which rendering should be done

synchronized void vanetsim.gui.Renderer.drawStaticObjects ( BufferedImage image )

inline

This function renders all non-moving objects on a supplied image. All streets and other static objects are rendered into the cached Image in this function. This function should only be called on

size changes of the drawing area
zooming or panning
map loading
new map objects appearing

Note: The main performance factor here are the calls to draw() or drawLine(). This is a factor determined by the underlying graphics subsytem and there's not much space for lot of improvement. Multithreading approaches are not possible here: The graphics subsystem is just singlethreaded (blocks concurrent draw-Calls even if they are done on different BufferedImages) and so there's no performance benefit.
Optimizing anything concerned with iterating through the regions is not worth it because the cpu time for this is barely measurable after using ArrayLists instead of Iterators (iterators create lots of object creations and calls)

image the BufferedImage on which rendering should be done

synchronized void vanetsim.gui.Renderer.updateParams ( )

inline

Updates various internal parameters after changes through panning or zooming.
The regions which shall be drawn are calculated here. They are a little bit larger than normally necessary in order to correctly display communication distance and mix zones. Otherwise, the distance of a vehicle, which is a little bit outside the currently viewable area wouldn't be drawn. This all induces a little bit of an unnecessary overdraw to the static objects but this should not matter a lot.
