Slow resume, need help speeding it up
« on: May 23, 2012, 07:04:46 am »
I'm trying to speed up resuming of a 3d world, something near the speeds of our iPhone version if possible.
Basically the 3d world is in an activity and I need to resume that activity as fast as possible.

Any other optimisations I try in code causes JPCT to crash. So looking for some suggestions.

Here is the basics of my code:
Code: [Select]
@Override
    protected void onCreate(final Bundle savedInstanceState) {

        synchronized (InputWorld3dActivity.masterLock) {
            if (InputWorld3dActivity.inputInstance != null) {
                ReflectionHelper.copy(InputWorld3dActivity.inputInstance, this,1); //Copies all activity data across to this one.
                if (this != InputWorld3dActivity.inputInstance) {
                    InputWorld3dActivity.inputInstance.finish();
                }
            }
            InputWorld3dActivity.inputInstance = this;
        }
        super.onCreate(savedInstanceState);
        setContentView(R.layout.wwlayout);
        boolean isOpenGl2 = false;

        mGLView = (GLSurfaceView) findViewById(R.id.glsurfaceview);

        PhoneRank.printPhoneStats();

        if (PhoneRank.isSafeForOpenGL2WithAA(this)) {
            try {
                if (GraphicsHelper.turnOnOpenGL2(mGLView)) {
                    final AAConfigChooser aa;
                    if (PhoneRank.getMaxAndFreeMemRank() == MemRank.VERY_HIGH) {// Most likely a top phone.
                        aa = new AAConfigChooser(mGLView, true);
                        Log.d("WW", "Turning on AA with transparency.");
                    } else {
                        aa = new AAConfigChooser(mGLView);
                        Log.d("WW", "Turning on AA without transparency.");
                    }
                    mGLView.setEGLConfigChooser(aa);

                    isOpenGl2 = true;
                    Log.d("WW", "Using OpenGL 2.0");
                }
            } catch (final Exception e) {
                //No OpenGL2 support.
                e.printStackTrace();
            }
        }

        if (!isOpenGl2) {
            Log.d("WW", "Using OpenGL 1.1");
            mGLView.setEGLConfigChooser(new EGLOpenGL1Chooser());
        }

        if (renderer == null) {
            renderer = new World3dBase(); //World3dBase is the GLSurfaceView.Renderer
        }
        renderer.setOpenGl2(isOpenGl2);

        mGLView.setRenderer(renderer);
}

Here are the current logs:

Looks like getting stuck on "OpenGL context has changed(2)...recovering for renderer 1/0!" and shader compiling.

All these operations have to be done if the context changes and the speed in which they are executed depends on how fast the cpu/gpu can handle them. I don't see room for improvement here. You can try to disable VBOs. That should make these "creating buffers" operations go away, but it might be slower (usually, it isn't though). But apart from that, it takes 2 seconds to reinitialize things. Is this really a problem?

Seemed to have helped thanks.

This is on my Galaxy Nexus. Which is a lot quicker than all our other devices. But yes this is actually a major problem for us.
I'm currently working on input for wagon wheel and pitch map, each thing happens very fast in cricket and therefore we need to allow fast input. Even with the Galaxy Nexus it is still slow.

Is there any extra caching you can do? Force keeping things on the graphs chip or in memory? Black magic?

Edit:
I found that turning off OpenGL 2.0 on the med/lower phones helped with there slowness problem. It seems its the shader loading that slowing things down. However I want to keep OpenGL 2.0 on if possible for AA. Is there any optimisations/caching you can do there?

Nope, i can't cache anything there. Loading the source files isn't an issue. It's the compilation that takes its time and there's no way around this. It's speed solely depends on the speed of the shader compiler in the driver and you can't feed precompiled shader code like you can in desktop GL.
However, you can try a hack...
The default shaders are part of the jar. You can unzip the jar and replace all shaders that aren't used in your application with more or less empty vertex and fragment shaders (you might have to fiddle around with the attributes and uniforms...i'm not 100% sure if the engine expects some of them to be there in all cases). That should reduce compilation time of these shaders (i'm not sure by which amount though...). Detecting which shaders are actually used is a trial and error process. You can derive their purposes roughly from the name...

Thanks for the help. That does sounds a little annoying heh.

What about OES_get_program_binary support?  ;D

I wasn't aware of this extension, because everything i always read said, that support for shaders is GLSL only...i'll look into it.

I can't find any support for this in the Java SDK. The NDK seems to have it though, but that's not worth much in this case. The SDK allows to upload shaders in binary format, but i can't find a way to get the binary from the driver...and that would be needed.

Bugger I can't find anything else either. I'll try asking on Stackoverflow.
