I have a problem here.I am trying to load a.md2 model first by using Loader.loadSerialize....() method.The size of .ser file is 363 kb.The original size of the .md2 file is 370kb.But at this time there is no error reported in the console and the model does not load or display in the screen or not getting any error on the console. So I decided to load the model using Loader.loadMd2() method. It loads all the animations and finally it says model loaded and followed by it throws this error.This error happens exactly at this line.

Code Select

world.compileAllObjects(fb);

=========The method that loads the md2 model
So I removed all of the animations except one from it.But still I am getting the same error.
Code Select

private Object3D drawCrabs(){
       Object3D crab = null;
                Resources res = getResources();
         //       try {
                    System.out.println("Start loading crab md2 model");
                    crab = Loader.loadMD2(res.openRawResource(R.raw.crab), 0.1f);
                    //crab = Loader.loadSerializedObject(new GZIPInputStream(res.openRawResource(R.raw.crabser)));
                    System.out.println("End loading crab md2 model");
         //       }
         //    catch (IOException ex) {
           //     java.util.logging.Logger.getLogger(GameActivity.class.getName()).log(Level.SEVERE, null, ex);
         //   }
                //crab = Loader.loadSerializedObject(res.openRawResource(R.drawable.crabser));
               // crab = Loader.loadMD2(getAssets().open("model/crabser.ser"), 1.0f);
              //  Bitmap image = BitmapFactory.decodeResource(res, R.drawable.crab1);
              //  Texture texture = new Texture(image);
             //   TextureManager.getInstance().addTexture("crabone", texture);
             //   crab.setTexture("crabone");
               // removing some of the animation sequences from the model
                    int flip   = crab.getAnimationSequence().getSequence("flip");
                    int salute = crab.getAnimationSequence().getSequence("salute");
                    int point  = crab.getAnimationSequence().getSequence("point");

                    int pain   = crab.getAnimationSequence().getSequence("pain");
                    int jump   = crab.getAnimationSequence().getSequence("jump");
                    int taunt  = crab.getAnimationSequence().getSequence("taunt");

                    int crdeath  = crab.getAnimationSequence().getSequence("crdeath");
                    int death  = crab.getAnimationSequence().getSequence("death");


                    crab.getAnimationSequence().remove(flip);
                    crab.getAnimationSequence().remove(salute);
                    crab.getAnimationSequence().remove(point);

                    crab.getAnimationSequence().remove(crdeath);
                    crab.getAnimationSequence().remove(death);
                   
                crab.compile();
             //   crab.strip();
                crab.build();
                System.out.println("....Returning from draw method...");
            return crab;
   }

I am using netbeans android emulator for development.

Maybe something else is too large then. Can you post the complete log output?

Simply looks like as if the model is too large, which is a bit odd. Can you upload that model somewhere to verify this?

I actually the model that I am using not made my me.It is used for some C++ openGL game application.I am just re using the model here. However, I can upload the model here:
http://code.google.com/p/androiddemogame/downloads/list.
From there you can download the models.

This model is actually not that small. It has 715 polygons and 420 unique vertices * 198 keyframes, i.e. it uses a total of >140.000 polygons and >83.000 vertices. However, you can get rid of most of this data, simply because it isn't needed in most cases. Just do a call to

Code Select

crab.getAnimationSequence().strip();


and most of the data of these 140.000 polygon will be removed because it isn't needed for animations only. I just can't do this by default, because one might want to access it in some cases.

I have one clarification here. Using jPCT for desktop, if I call the above method and serialize the model, will the actual size of the model will reduce so that I can use it in AE version?

EgonOlsen

Good question. It should work, but i think i've never really tried it myself. Just give it a try. If it doesn't work, it's a bug and should be fixed.

This is the current method I am using serializing the model.
Code Select

      private void serializeTheModel(String modelName) {
        System.out.println("[inside serializeTheModel methiod]") ;
        Object3D model = Loader.loadMD2(modelName, 0.1f);
        model.getAnimationSequence().strip();
        model.compile();
        model.build();
        DeSerializer serializer = new DeSerializer();
        try {
              serializer.serialize(model, new FileOutputStream("crab.ser"), true);
        } catch (IOException ex) {
            java.util.logging.Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }
        System.out.println("[ serializing the model is over......]") ;
      }

After this method execution, the size of the model becomes extremely large.It comes around 2 MB!. I do not have any idea why this is happening.

That's a normal size for a serialized model. MD2 uses a lossy compression to keep files small. The best way to deal with serialized objects is to zip them and load them via a ZipInputStream.

the problem is that when I serialize it, I am not able to load the model in AE.Also,, I tried the way you had suggested in the earlier post.But that way it is not reducing the size of the model

Why not?

I was able to load the model that is available in the alien runner AE application.That is loading.This is the code that is used to load it.
Code Select

private InputStream loadZip() {
    ZipInputStream is = null;
    Resources res = getResources();
    is = new ZipInputStream(res.openRawResource(R.raw.crab));
    try {
  is.getNextEntry();
} catch (IOException e) {
  throw new RuntimeException(e);
}
    System.out.println(" the value of is "+is);
    return is;
   }

I serialized my model and later zipped it manually as you suggested after removing  many of the unwanted animation sequences by just leaving one animation and called strip() method on it with the following code. At this time, the size of the model was reduced considerably less.But when I loaded the model with the above method,I am getting the following exception.
Code Select

private void serializeTheModel(String modelName) {
        System.out.println("[inside serializeTheModel methiod]") ;
        Object3D model = Loader.loadMD2(modelName, 0.1f);
        Animation animation = model.getAnimationSequence();
        animation.remove(animation.getSequence("stand"));

Might be that i don't handle stripped animations correctly. I'll look into it.

I was able to resolve the issue here. I just serialized the model and loaded after stripping some of the animation sequences.The .md2 model loaded successfully.But when I told that it was not working means I have some other objects also in the screen.Along with those objects, this model is not displaying.I came to know this when I commented some part of the code where it is loading the other models. :).Thanks for your support.However,I was able to understand some more things!.I  just loaded the model by serialzing it.
