Support / loadSerializedObject problem

« on: September 16, 2010, 04:21:31 am »

I try to load big md2 file
The file size is 665Kbyte.

So I did like follow
-In desktop JPCT

InputStream fis = new FileInputStream("obj.md2");
		OutputStream fos = new FileOutputStream("obj.ser");
		DeSerializer de = new DeSerializer();
		Object3D myobj = Loader.loadMD2(fis, 1);
		myobj.build();
		de.serialize(myobj, fos, true);

-In jpct-ae

Code: [Select]

Object3D obj = Loader.loadSerializedObject(con.getResources().openRawResource(R.raw.obj));but android attached error.

Support / How to get 3D position by clicking 2d position?

« on: September 07, 2010, 05:50:03 am »

How to get 3D position by click 2d position?
I did follow
Vector3f rayTo = new Vector3f(renderer.getRayTo((int) event.getX(), (int) event.getY()));

CollisionWorld.ClosestRayResultCallback rayCallback = new CollisionWorld.ClosestRayResultCallback(cameraPosition, rayTo);
dynamicWorld.rayTest(cameraPosition, rayTo, rayCallback);
if (rayCallback.hasHit()) {
Vector3f vec = rayCallback.hitPointWorld;
}

but position is incorrect, What am I doing wrong?
