Hi, recently i deserialied an OBJ using jPCT's Desktop Version. (Deserializer)
I Got the resultant .ser file but the problem is that when I try to use that .SER in HelloWorld-AE Example, All I see is the blank screen.

Here's how I deserialized the OBJ file.


static Object3D cube = null;

public static void main(String[] args) {
// TODO Auto-generated method stub

try {
cube = Object3D.mergeAll(Loader.loadOBJ(("models/cube.obj"), null, 10));
cube.build();
new DeSerializer().serialize(cube, new FileOutputStream("ser/cube.ser"), true);
System.out.println("done:");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}


And this is what I did in HelloWorld-AE Example...


      cube = Loader.loadSerializedObject(res.openRawResource(R.raw.cube));
      cube.build();
      world.addObject(cube);


Hope anyone can solve my query.

Thanks for the projects, i'd like to say that the prototype one is working. Just need to clean up my project all the time before running it.
Its a great help to me to understand the concepts more clearly and more clear jPCT-AE

Thanks a lot Egon, I've activated my account. Also thanks for the prototype projects you sent to me.
I sure will post anything related to jPCT-AE in the wiki.

Hello Egon, are there any other resources available other than the AlienRunner-AE game, So that we can dig in with a few more references?

Hello Egon, I'd also like to contribute to the wiki, if you dont mind.

Okay, Thanks for the support.
And I've seen the ninja example that is implemented using Bones in Android.
So All the animation poses will be defined by the 3d animator or by the programmer's end?

Okay, I have one more Question to ask.
There is an OBJ file named minicooper.OBJ of size more than 6 MB which took 30sec to load on a device powered with mali.
Anyways the point is, I got it serialized to a size of 10Mb, Now wont that increase the size of my Apk ?

Both the objects(OBJ files) loaded  correctly without any issues...

Hi again,
After reading the wiki, I tried the following code.. and i got this..where am i wrong?

static Object3D cube;
   
   public static void main(String[] args) {

      
      cube = Object3D.mergeAll(Loader.loadOBJ(("models/airboat.obj"), null, 10));
      try {
         new DeSerializer().serialize(cube,  new FileOutputStream("models/cube.ser"), true);
      } catch (FileNotFoundException e) {
         // TODO Auto-generated catch block
         e.printStackTrace();
      }
        cube.build();
   }

The problem is, the obj file is of 301kb but the .ser file is greater than 1mb. Wont it affect the performance of the system?

The desktop version isn't running properly.
I am getting this as an error in the desktop version..
please see to it.

Okay, sure I have downloaded the desktop version for the same. I have read the javadoc for it but I am clueless on how this works?

Sorry for asking this silly question but I am a newbie here.

Hope you don't mind

How to do it in Android?

Hello Egon,
Is there any other way to convert an OBJ into .SER?
or should we just go with the plugin itself?

I've achieved the loading of OBJ files.... just replace the code in hello world..

/*cube = Primitives.getDoubleCone(20);
            cube.calcTextureWrapSpherical();
            cube.setTexture("texture");
            cube.strip();
            cube.build();
world.addObject(cube);*/

by this...

cube = Object3D.mergeAll(Loader.loadOBJ(getResources().getAssets().open("airboat.obj"), null, 10));
               cube.build();
               world.addObject(cube);

be sure to surround this snippet by a try catch block.
hope this helps.

Hello everyone, i am new to jpct engine and i've tried some examples given on the website. Tried loading some .obj file and it worked fine.

however, i have a question that it is mentioned that jpct-ae also uses .ser files but I dont know how to convert (obj, 3ds etc ) into
.ser format.

Do i need to write my own code for this or is there any other method?

Please help.

Sid,
