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.
public void run() {
Config.glDynamicBatchSize = 4000;
projector = new Projector();
projector.setFOV(1.5f);
projector.setYFOV(1.5f);
sh = new ShadowHelper(theWorld, buffer, projector, 512);
sh.setCullingMode(false);
sh.setAmbientLight(new Color(30, 30, 30));
sh.setLightMode(true);
sh.setBorder(1);
sh.addCaster(hero.get(0));
sh.addReceiver(ground);
sun = new Light(theWorld);
sun.setIntensity(250, 250, 250);
sun.setAttenuation(800);
theCamera.setFOV(1.5f);
System.out.println("\n\n\nFinished shadows.\n\n");
}

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.
-
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.
-
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.
-
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.
-
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!

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

Looks fien at first glance. Could you post your render-"loop"?
-
No problem:
private void draw() {
buffer.clear();
skyBox.render(theWorld, buffer);
if (!softwareMode) {
if (!doShadows()) {
theWorld.renderScene(buffer);
theWorld.draw(buffer);
}
buffer.update();
buffer.displayGLOnly();
glCanvas.repaint();
}
else {
theWorld.renderScene(buffer);
if (wireframe)
theWorld.drawWireframe(buffer, Color.blue);
else theWorld.draw(buffer);
buffer.display(glCanvas.getGraphics());
}
}
private boolean doShadows() {
if (sh == null || storyMode)
return false;
SimpleVector offset = new SimpleVector(1, 0, -1).normalize();
offset.rotateY(0.07f);
projector.lookAt(ground.getTransformedCenter());
SimpleVector position = hero.getRoot().getTransformedCenter();
position.y -= 30f;
position.z += 5f;
projector.setPosition(position);
//projector.setPosition(hero.getRoot().getTransformedCenter());//hero.getRoot().getTransformedCenter()
//projector.moveCamera(new SimpleVector(0, -1, 0), 200);
//projector.moveCamera(offset, 215);
sun.setPosition(projector.getPosition());
sh.updateShadowMap();
sh.drawScene();
return true;
}
-
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!?
-
No shadows at all. And no, I called sh.addReceiver(ground) and there's only one ground on the entire model.
Any suggestions?
-
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.
-
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.
-
OK, I just got around to porting the AdvancedExample, per your suggestion. "Got here.0" gets printed, "Got here" does not (so we're back to the shadow code not completing). Gotta be a bug (or "issue") of some kind. Please run this for me and see for yourself.

There's no issue, you just have the wrong order. Like i posted before:
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
You have to make the component visible BEFORE setting up the ShadowHelper or otherwise, it will never terminate, because it waits for a drawing event that will never happen. This might feel clunky, but the design of LWJGL's Canvas enforces it.
Just take the setSize/setVisible-lines and move them right before you create the ShadowHelper. And remove the call to Display.isCloseRequested in addition...it doesn't work in a non-native window, because there is no Display being created.
-
OK, so it works and the shadows are visible. I'm thinking my world might be too small (I'm exporting the OBJ level at a scale of .06). Could that be it? If so, other than scaling everything up, is there a workaround?
-
When is the "VBO created" message printed? Could the lack of visible shadows come from the fact that the "VBO created" messages are happening after setupShadows()?
-
VBOs will be created when the mesh data gets uploaded to the GPU. It has nothing to do with shadows and you can even disable it in Config if you want to.
-
What about the other part of my question (the size )?
-
I'm not sure about the size....it might matter somehow but i don't think that it can cause shadows to disappear. Have you checked you far plane setting? Maybe it's to narrow so that the scenes gets clipped when viewed from the light source?
-
Two things:
1) the following code works (it's the exact same code as is in the program where it doesn't). So is it possible that some models can't be shadow receivers (perhaps something about their normals)?
2) 2 new VisibilityLists are being created. You keep telling me it's about swallowing Exceptions, but it never was for me, and this almost always happens.
By the way, if instead of translating the cube by -3f on y I translate it by -1f, the shadow becomes VERY "edgy" (very large squares).

Every model can be a shadow receiver. There's no relation to normals in any way. What is required is that the model has to be able to take the addional texture layer that the ShadowHelper adds to it, but for normal, single textures objects, this shouldn't be a problem. Are you sure that the position of the light in your non-working case is fine? Too far away and there won't be a shadow. The fact that it fest blocky in your example might be an indication for this. Try to lower the distance to see if that helps.
It's totally fine that additional visibility lists will be created when using the the ShadowHelper. The problem is when this happens every frame and that usually is the result of swallowing exceptions.
I'll take a look at your example, when i'm back home. I can't do much from here.
-
I set both the light and the projector REALLY close just now to see whether I would get shadows and I still got none. I'm almost in the hero's face with the following code.
SimpleVector position = hero.get(0).getTransformedCenter();
position.z += 5f;
projector.setPosition(position);//hero.getRoot().getTransformedCenter()
projector.moveCamera(new SimpleVector(0, -1, 0), 3.75f);//200
-
Finally something to show for. I think it's a ShadowHelper bug because even this fraction of the shadow doesn't appear in most areas of the ground (the only receiver):
(http://ratto.co/ShadowProblem.jpg)
-
I tried your box test case, but i'm not sure what it's about to tell me other than that test case works?! That the shadow gets edgy is totally normal, because you are looking at it from a very close distance at a very low angle...every unfiltered texture would look that way in that scene and the shadows won't be filtered, so the result is to be expected.
About your screen shot..well, you have to keep in mind that a view frustum will be created for the shadow map just like the one for the camera. If you are moving pretty close to something, that frustum doesn't much of the geometry that is close. And i think that this is what you see in the screen shot. Everything else is just out of the frustum. Try to increase the fov (watch the stupid minFov and maxFov settings...) in the Projector and the result should change. If it does, try to move the projector out step by step to see what happens then.
-
I'm not sure to which test you're referring, but it's nothing recent and it certainly wasn't done after I saw this fraction of a shadow. I'll play with FOV and report my findings, but I don't think that's it (in my opinion it's related to the complexity and size of the floor).
-
I'll play with FOV and report my findings, but I don't think that's it (in my opinion it's related to the complexity and size of the floor).
The shadow mapping doesn't care about complexity as long as all parts (if there are more than one) have been added as receivers. It might help to render the floor as wireframe in addition to see the actual polygons.
-
Check this out. Setting minimum FOV to .02f helped, but didn't solve it. The further ahead I move, the less of the shadow there is. A few steps ahead of the second screen there's no shadow at all. But on another part of the ground (merged together with that one in Max), the shadow is complete again, until it disappears again. In total there are four parts of the floor, each behaving the same way.
(http://ratto.co/ShadowProblem2.jpg)
-
Could you please render the ground's wireframe in addition? I would like to see if it happens on the borders of polygons or not.
-
Here you go:
(http://ratto.co/ShadowWireframe.jpg)
-
Ok...i see no relation to the actual polygons...i'm out of ideas. I need some test case that reflects this problem properly to investigate it.
-
I'll send you the first test case with this ground model, then.
-
The test case is missing the actual hero mesh, so i replaced it with the ninja from the Bones examples. It didn't work too well, because all i got to see was the sword and some funny looking ground object. However, i got this:
WARNING: You've exceeded the configured triangle limit for the visibility list. Consider adjusting Config.maxPolysVisible!
If you get that too, it explains a lot. Just do what the warning says and see if it helps. Or switch to compiled objects, which won't cause this problem anyway.
-
Yeah, sorry, my program compiles the objects. If I'd known, I would have compiled them on the test case, but alas, that's not the problem. What happened when you compiled the ninja?
-
Hard to tell...with this test case, i don't even see the ninja...just its sword hovering high above some strange looking thing that is supposed to be the ground. It's impossible to tell anything from this, i'm afraid. I'm not even sure what i'm looking at... ???
-
I sent you both my character and the ground textures. Should help visualization.
-
Yes, that helps. Now i can see the issue and know what happens here. It's caused by the fact that you are using the center of the ground as lookAt-point, i.e. as the center of the projector's view frustum. You then place the projector a little before/behind (i changed that in the test case to see any shadow) and above the hero. Depending on the angle between the ground plane (simplified to ease thinking...) and the lookAt-vector, the frustum doesn't cover the whole hero mesh. If that's not clear, try to make a simple drawing (it helped me).
If you want to use the shadows that way, either use some point before the hero as the lookAt point instead (like projector.lookAt(position);) or try to setup the projector in a way that it really acts like the sun would do, i.e. the frustum has to cover the whole ground mesh and the position never changes.
-
I'm not sure whether I completely get it. Perhaps if you sent me your drawing?
On a separate question, what about Object3D.mergeAll breaks the collision tests? If I store the collision objects as multiple parts, collision works. But then, I have to have a loop for each gameloop iteration to set visibility on then off again. But if I mergeAll, collision stops working.
-
Well...somehow like this:
(http://jpct.de/pix/abstract_art.png)
About merging: It has no effect on collision detection. Collision detection doesn't care about the source of the mesh it's working on. Make sure to enable collision detection for the resulting mesh (merging doesn't do this) and if you use octrees, calculate for the final mesh, not for the source meshes.
-
I see your point, thank you. I will play with it. If the problem persists, I will report back.
-
How do I make the shadows less blocky now? You mentioned it was supposed to be unfiltered or something, but the result of leaving the light static, while solving most of the getting-all-the character problem, is that the shadow is now a collection of fairly large squares.
-
You have basically three options:
- Increase the resolution of the shadow map.
- More the projector closer to the scene.
- Decrease the fov of the projector (which is similar to 2 in effect)
