ShadowHelper Code Never Completes

[AGP]

The following lines never complete (I put it in its own thread BECAUSE it was locking my program). The video hardware is NVidia GeForce GT 540M.

I don't know in which context you call run() (some extra thread of yours?), but when using the AWTGLRenderer, you have to ensure that the paint()-method of the component can run, i.e. that the component is able to repaint itself while initializing the ShadowHelper. The ShadowHelper has to query the driver for information about the supported modes and this can only be done in the rendering thread, i.e. in the paint()-method. So the ShadowHelper has to wait for the next repaint of the component to happen to get this information. If, for whatever reason, this repaint never comes, the ShadowHelper never returns.

[AGP]

I said it was moved to a separate thread because it locks (hence, the run() method). I'm not overriding paint(Graphics), I use my own draw() for active rendering, but I did call glCanvas.repaint(), super.repaint(), and even super.paint(this.getGraphics()). None helped.

[EgonOlsen]

Under normal conditions, it works fine. So you are doing something that prevents the canvas from being repainted. What you are supposed to do:

• enable the GLCanvasRenderer on the FrameBuffer
• add the canvas to your frame/component
• make your frame/component visible and active
• setup your ShadowHelper

There shouldn't be any need to call repaint()/paint()/whatever() yourself nor do you have to spawn another thread because the rendering already takes place in the AWT event dispatch thread, which happens in parallel to your own code.

Just make sure that you aren't blocking the AWT event dispatch thread from executing at the time you are setting up the ShadowHelper and that the canvas is visible and can be repainted.

[AGP]

I don't know what I changed about it (it wasn't the order of the operations, but I did leave the repaint calls in), but it completes now. Problem now is that the screen gets stuck on black. The following is ShadowHelper's console output. The ShadowHelper is configured for a 512x512 map. Its initialization is no longer on a separate thread, as that's no longer needed.

OK, never mind that, it was an unrelated problem. Still, though ShadowHelper completes and though I do

SimpleVector offset = new SimpleVector(1, 0, -1).normalize();
offset.rotateY(0.007f);
projector.lookAt(ground.getTransformedCenter());
projector.setPosition(hero.get(0).getTransformedCenter());
projector.moveCamera(new SimpleVector(0, -1, 0), 200);
projector.moveCamera(offset, 215);
sun.setPosition(projector.getPosition());
sh.updateShadowMap();
sh.drawScene();


before calling buffer.update, I see no shadows being cast.

[AGP]

By the way, I ran the AdvancedExample on this computer and it has no trouble casting shadows. I've compared both programs to death, and, for the life of me, can't tell the difference. I thought it might be Bones's fault, but I added a cube from the Primitives class and added it as a caster and I still get no shadows.

Also, I have since replaced the snork.md2 model on the AdvancedExample with my Bones model, using my initialization code, and it worked. But it won't work on my own program!

[EgonOlsen]

Any suspicious log output? I doubt it, but you never know so maybe you could post the log...

[EgonOlsen]

Looks ok...and the result is...everything is shadowed? No shadows at all? Are you sure that the objects that should be receivers actually are? Maybe you missed that part somehow or are working on copies the objects or something like that!?

[AGP]

No shadows at all. And no, I called sh.addReceiver(ground) and there's only one ground on the entire model.

Any suggestions?

[AGP]

Is it possible that it's a ShadowHelper bug related to the use of AWTGLFrame? The only difference I see between the AdvancedExample and my program is that I'm using an AWT frame.

[EgonOlsen]

I don't of any bugs. I've multiple test cases for using shadows in an AWTGLCanvas and they all work fine. I suggest to take the advanced example and port it to use AWT instead. If that works, try to spot the difference between it and what you are doing.
