Exception access violation

[Chade]

I created a new project in Eclipse through the antfile (build.xml). Started playing with the the BasicDemo. The compass appears for about half a second, then disappears, and after a while (30 seconds - 1 minute) the program crashes with an Exception Access Violation.

Any ideas on what's gone wrong would be appreciated. Cheers....

[patmurris]

Is this your first try at compiling and running wwj ?
Does the distribution worldwind.jar works ?

[Chade]

Yeah, pretty much my first.

zzz. I was just typing that worldwind.jar works fine... and it crashed, same way, same error.

[Chade]

The joy of new drivers. I though mine were up-to-date. Obviously not.

Anyway, crashing solved, now for the lack of the compass showing. worldwind.jar shows the compass, but it disappears from my build within a second... Hmmm.

Days later:
jdk 1.6, and the latest jogl, would help...

[what_nick]

Some sort of culling going on vs placenames, Patrick have you seen this before ?

[patmurris]

... not sure i understand what is going on here...
Personaly, i havent seen the compass disapear. All 2D overlays (compass, scalebar, worldmap) are processed as OrderedRenderables with a fixed small 'distance from eye' so that they paint on top. Maybe there is a glitch in there ?

[Chade]

Yeah, never mind it, I just needed to update to jdk 1.6, and the latest jogl library. >.<

I am getting this Exception Access Violation on the Eventqueue thread like Chade was. I am running the latest Java and jogl, so the same fix doesn't work for me.


My process:

I am working on a team using WW, we are loading traffic data from a database. This data refers to flight paths, flights in the air, and roadway with cars on them.

I have a thread that runs a loop gathering all the information for display and passing it into a drawing class. This drawing class talks to the required classes for worldwind to display polylines and paths and roadways.

here is a look at the Flight Path code. This code is run to redraw the flightpaths each time. I am wiping the screen and repainting with the new paths and the old ones.

rendering = true;
	final ArrayList<LatLon> positions = new ArrayList<LatLon>();

	qqLayer = getQQLayer();

	Collection<Renderable> polyLines = qqLayer.getRenderables();
	polyLines.removeAll(polyLines);
	polyLines.clear();

	for (int i = 0; i <= flightPth.size() - 1; i++) {
	    FlightPath path = flightPth.get(i);
	    qq.mob.cc.dao.LatLon pathLL = path.getThere();
	    LatLon there = new LatLon(Angle.fromDegrees(pathLL.getLatitude()),
		    Angle.fromDegrees(pathLL.getLongitude()));
	    LatLon here = new LatLon(Angle.fromDegrees(36.0814), Angle
		    .fromDegrees(-115.1549));

	    positions.add(there);
	    positions.add(here);

	}

	Color interiorColor = new Color(0f, 0f, 1f, 1f);

	final Polyline polyline = new Polyline(positions, 5000);
	polyline.setPathType(Polyline.LINEAR);
	polyline.setColor(interiorColor);
	polyline.setFollowTerrain(true);
	polyline.setAntiAliasHint(GL.GL_NICEST);
	qqLayer.addRenderable(polyline);

	WorldView.wwd.repaint();
	rendering = false;

It seems to me that the error is caused by two aspects of this process accessing the same piece in memory, causing the JVM to crash.

This is a toughie and I would like some suggestions for moving forward.

-Shaun

[patmurris]

Could you determine at which point in the code the conflit occurs? polyLines.removeAll(polyLines);? qqLayer.addRenderable(polyline);? How can it crash glDrawArrays()...

I see you have a rendering flag. How is it used in the rendering/updating process? This seems like a way to avoid rendering and modifications to the render list to clash... i guess not enough

[Shaun]

Here is a portion of code from the Loop processing Class.

List<FlightPosition> flightPosL = futureFlPos.get();
		if (flightPosL == null) {

		} else {
		    if (!wwDraw.rendering()) {
			wwDraw.drawFlightPosIcons(flightPosL);
		    }

		}

I am using the flag to see if its acceptable to send more data to the drawing class.


How would I go about determining which piece causes the crash? I am willing to look where I am told, I just don't see the direction to look yet.
