Post by: elmatos on September 30, 2013, 08:29:51 PM

Hi there!

First of all i would like to thank the developer(s) for this awesome tool!

Now getting to the point of this post:

I was trying to load an .obj file like the title says but i'm having the following exception thrown:

09-30 18:03:48.067: E/AndroidRuntime(2378): FATAL EXCEPTION: GLThread 5227

09-30 18:03:48.067: E/AndroidRuntime(2378):    at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240)

I used the example class hello world and only changed some code on the onSurfaceChanged (see bellow)

if (fb != null) {
   fb.dispose();
}
fb = new FrameBuffer(gl, w, h);

if (master == null) {

   world = new World();
   world.setAmbientLight(20, 20, 20);

   sun = new Light(world);
   sun.setIntensity(250, 250, 250);

   // Create a texture
   Texture texture = new Texture(BitmapHelper.rescale(BitmapHelper.convert(getResources().getDrawable(R.drawable.objectTexture)), 64, 64));
   TextureManager.getInstance().addTexture("texture", texture);

   Object3D[] s = Loader.loadOBJ(getResources().openRawResource(R.raw.object3d), null, 1); <<--Error occurs where
   Object3D = Object3D.mergeAll(s);
   Object3D.setTexture("texture");
   Object3D.strip();
   Object3D.build();

   world.addObject(Object3D);

   Camera cam = world.getCamera();

(unchanged content...)

The .obj file can de downloaded in the following link:

I would be much appreciated for some help in this matter :)

That was a bug in the loader. It expected the obj-files to have at least some kind of header. Should be fixed in this jar: jpct.de/download/beta/jpct_ae.jar (http://jpct.de/download/beta/jpct_ae.jar)
