LiveWallpaper Shader Problem

[MrM]

I've got JPCT-ae working with markguerra's LiveWallpaperService, and the only problem's I've had so far was the Texture inpus, since texturemanager is a singleton but that's bypassed with a few ifs.

My problem are the shaders, I can't get them working at all, it's as if they're not used, while logcat says they're loaded, and debugging shows no problems. If I blend them, the normal map is dominant, and it's like IT IS the face map. I'd appreciate it if somebody could take a look at what I'm doing wrong, I'm guessing it's where I instance the renderer or probably at the Engine. The complete Eclipse project, along with jpct and the wallpaperservice libraries are at this link:
http://www.mediafire.com/?yyfchd20h71jotj

[MrM]

These are shots from the device:

This is how the application looks like:


And this is how the LiveWallpaper looks like:


As you can see, the LiveWallpaper is flat, and it's more on the purple side, because of the normal map being blended. The texture settings are the same for both the application and the Live Wallpaper.

Would anybody take a look at the project? I'm at wits end

[EgonOlsen]

Do have a log output where jPCT initializes the renderer? Are you sure that ES 2.0 actually works in the context of a wall paper?

I might have made an oversight:
I haven't checked for ES 2.0 compatibility.

[MrM]

I could'n find anything better than this:
http://www.youtube.com/watch?v=k3SVtxNvk4E

I'd conclude ES 2.0 indeed works with Live Wallpapers.
I can't see however why this:
[2011-09-11 19:30:17 - Emulator] I/jPCT-AE (  290): OpenGL version:    OpenGL ES-CM 1.0
is initalized.
Maybe it's an oversight in the livewallpaper library?

[EgonOlsen]

This is even more disturbing: Android PixelFlinger 1.3

...that means that you are running your wallpaper on Android's software renderer implementation which (apart from the fact that it doesn't support ES 2.0 anyway), is slow and buggy and should be avoided at all costs...no idea why this happens. Most likely, it has to do something with your initialization code being faulty somehow...

[MrM]

All Right, I got over my initialization issues, but now I have different problems:

It seeems to me that the problem arises when trying to compile to the framebuffer. The code in OnSurfaceChanged, where the objects are compiled, is the same as in the HelloShader example. Do you have any suggestions that could solve this? Or whatever pops in your mind?

[MrM]

If I get rid of all the FrameBuffer lines (in on SurfaceCahnged and in onDrawFrame), it works! Of course it doesn't render anything, just a black screen, but my point is, it's probably the FB.
Any other way to compile and render stuff?

[EgonOlsen]

How are you creating the FrameBuffer? Make sure that you are using the constructor without the gl context.

[MrM]

That was it! I can't thank you enough, I'll post some images later, once I've got it set up, to show you how JPCT-ae looks using GL ES 2.0 with LiveWallpapers. 

[EgonOlsen]

Ok...i'll try to catch this case (gl context provided but ES 2.0 actually wanted) then, as it might be a common problem.

[MrM]

Yeah, I can't believe I didn't check before doing anything... Didn't even cross my mind. And I've been trying to do it for DAYS now, tried a lot of different methods. I can't say which libraries actually work, because this one I've created on my own, sort of... It does contain a lot of other people's codes and snippets I've found lying about.

Nevertheless, JPCT works brilliantly, fps is off the mark, loading time is a bit long but that's probably in my code, a lot of sleeps (for testing), and stuff instanced where it shouldn't be.
If I can only find my camera charger to film a bit of it... I haven't found a good sreen capture application or program.

[EgonOlsen]

I looked into it and i'm asking myself how you were able to initialize ES 2.0 and still create a 1.1 gl context?

[MrM]

I'm not very good at explaining so I'll do the best I can:
(By the way, the project I've uploaded above, has been totally rewritten, it's no longer valid)

I guess you could say that I have the Wallpaper Service (in a class different than the renderer) wrapped in a surfaceView.
I guess it's all about adding the ES 2.0 depth bits. Then I spawn the engine with the renderer from your example, and with a previously set ContextFactory, and ConfigChooser, in which you customize the rbga, depth and stencil. There is a config checker too in there somewhere too, which identifies if what you have chosen is valid.
These lines would interest you the most:

    private static class ContextFactory implements GLSurfaceView.EGLContextFactory {
    private static int EGL_CONTEXT_CLIENT_VERSION = 0x3098;       //This is where it all starts.
   
    public EGLContext createContext(EGL10 egl, EGLDisplay display, EGLConfig eglConfig) {
    int[] attrib_list = { EGL_CONTEXT_CLIENT_VERSION, 2, EGL10.EGL_NONE };  //These are from an EGL attribute list I've found. Pretty standard, just called with custom strings so it would make it easier.
    EGLContext context = egl.eglCreateContext(display, eglConfig, EGL10.EGL_NO_CONTEXT, attrib_list);
   
    return context;
    }
   
    public void destroyContext(EGL10 egl, EGLDisplay display, EGLContext context) {
    egl.eglDestroyContext(display, context);
    }
    }


protected class WallpaperEngine extends GLEngine {

public WallpaperEngine(Context context, MyRenderer renderer) {
super();

setEGLContextFactory(new ContextFactory());
setEGLConfigChooser(new ConfigChooser(5, 6, 5, 0, 16, 0));

renderer.setEngine(this);
setRenderer(renderer);
setRenderMode(RENDERMODE_CONTINUOUSLY);
}
}

public class MyWallpaper extends Wallpaper {  //This is a class which extends the GLWallpaperService which I've got from Robert Green, and modified it a bit. It only overrides the engine.
private MyRenderer mRenderer;              //It's mostly setters and overrides.

@Override
public Engine onCreateEngine() {
mRenderer = new MyRenderer(this);
return new WallpaperEngine(getBaseContext(), mRenderer);
}
}



This is from the config chooser class, which implements GLSurfaceView.EGLConfigChooser, and actually specifies the ES2.0:

        private static int EGL_OPENGL_ES2_BIT = 4;
        private static int[] s_configAttribs2 =
        {
            EGL10.EGL_RED_SIZE, 4,
            EGL10.EGL_GREEN_SIZE, 4,
            EGL10.EGL_BLUE_SIZE, 4,
            EGL10.EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
            EGL10.EGL_NONE
        };


I've added comments to simplify. The device is Samsung Galaxy Mini with 2.2 (FROYO) by the way... All debugging and testing were done on it, I don't trust the Emulator when working with GL stuff.
Getters and Setters for the engine and surfaceView should be made in the Renderer class accordingly, if you'd like to use preferences for Activity.

I'm not sure if I've been very clear, but as I said, I'm not very good at explaining. Take a look at:

Anyways, here's the video:

Sorry about the blank side on the Primitive, this is only a test.
And yes, one of my accounts is Nitrus015, I've been asking you about the Parallax mapping on your video, while I was still doing research on GL for android 

[EgonOlsen]

Well, that's no exactly what i meant... i don't get how you managed to create a FrameBuffer with a GL10 implementation. Where does it come from? GL10 is an interface for GL1.0. You can't implement it with GL 2.0 (well...you can. I'm doing it internally, but anyway....). On Android, you either have an implementation of GL10/GL11, which means that you are using a GL1.0/1.1 context or you have a GL2.0 context but then, you don't have any implementation of the GL10 interface. I'm just asking because i'm unsure what to check for to detect this case.
