I found this example that makes the 3ds file into a xml file. Still cant get it to work properly though.

http://www.bayninestudios.com/2011/01/importing-3d-models-in-android/

I guess there is something wrong with my file system now.... I get a little red x on my 3ds folder.

try {
InputStream isLeaf = new FileInputStream("C:/Users/Ian/workspace/jpctLoadModel02/3ds/lilacleaf1.3ds");
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
     
leafModel = Loader.load3DS(isLeaf,1);

Like this? Oh well i will keep plugging away 

still getting the same thing in logcat


TextureManager.getInstance().addTexture(leafTexture);

InputStream is = new ByteArrayInputStream(leafModelName.getBytes());
   
System.out.println("loaded");   
leafModel = Loader.load3DS(isLeaf,1);
       
        Camera cam = world.getCamera();
cam.moveCamera(Camera.CAMERA_MOVEOUT, 50);
SimpleVector sv = new SimpleVector();
        for (int i = 0; i < leafModel.length; ++i) {
        leafModel[i].build();
world.addObject(leafModel[i]);
cam.lookAt(leafModel[i].getTransformedCenter());
sv.set(leafModel[i].getTransformedCenter());
        }

I tried to use a string but it wont let me, but i get an error that says only a string is allowed.

Do i need to create a jar file like in this post?

Ok i updated and changed the libs folder but now i get this error.

Anyone run into this before?

 

I have the texture in jpctLoadModel02/res/drawable-hdpi called leaf1.jpg and the leaf1.3ds file in jpctLoadModel02 default folder.

String[] leafTexture = {"leaf1"};
String leafModelName = "leaf1.3ds";
InputStream isLeaf;
Object3D[] leafModel;

Then in the onSurfaceChanged method
Texture leafTex = new Texture(600,600);
        for (int i = 0; i < leafTexture.length; ++i) {
            TextureManager.getInstance().addTexture("res/"+leafTexture[i] + ".jpg");
        }
//Modelname string to inputstream
try {isLeaf = new ByteArrayInputStream(leafModelName.getBytes("UTF-8"));
      } catch (UnsupportedEncodingException e) {
         e.printStackTrace(); }

   leafModel = Loader.load3DS(isLeaf,1);
   Camera cam = world.getCamera();
   cam.moveCamera(Camera.CAMERA_MOVEOUT, 50);
   SimpleVector sv = new SimpleVector();
        for (int i = 0; i < leafModel.length; ++i) {
        leafModel[i].build();
world.addObject(leafModel[i]);
cam.lookAt(leafModel[i].getTransformedCenter());
sv.set(leafModel[i].getTransformedCenter());
        }

In the logcat it shows as:

Am i suppose to use another kind of Loader method or am i just looping through them incorrectly. I thought i would only get one Object3d file and then add that into the world, but it always crashes on me.

well i mean you can calculate the field of view.

yes i got it, thank you. 

Thanks for making such a great wiki, and i would love to take part in it.
