Question

I try to launch a 3D object in my app with min3d, but it crashes. I have followed this tuto : http://www.mat-d.com/site/using-min3d-for-android-frequently-asked-questions-common-texture-issues-blender-import/

Here’s the code :

package com.g171.zaloeil;

import min3d.core.Object3dContainer;
import min3d.core.RendererActivity;
import min3d.parser.IParser;
import min3d.parser.Parser;
import min3d.vos.Light;

public class Vue3D extends RendererActivity {

private Object3dContainer faceObject3D;

/** Called when the activity is first created. */
@Override
   public void initScene()
   {
    scene.lights().add(new Light());
    scene.lights().add(new Light());

    Light myLight = new Light();
    myLight.position.setZ(150);
    scene.lights().add(myLight);

    IParser myParser = Parser.createParser(Parser.Type.OBJ, getResources(), "com.g171.zaloeil:raw/cle1_obj",true);
    myParser.parse();

    faceObject3D = myParser.getParsedObject();
    faceObject3D.position().x = faceObject3D.position().y = faceObject3D.position().z = 0;
    faceObject3D.scale().x = faceObject3D.scale().y = faceObject3D.scale().z = 0.009f;
// Depending on the model you will need to change the scale
    faceObject3D.scale().x = faceObject3D.scale().y = faceObject3D.scale().z = 0.009f;

    scene.addChild(faceObject3D);

   }

@Override
public void updateScene() {
    faceObject3D.rotation().x += 0.5;
    faceObject3D.rotation().z += 1;
}
}

And here’s the logcat :

Does anybody know what could be missing ?

Answer 1

Resource not found exception.

You’re referencing a resource that you haven’t added to your package:

android.content.res.Resources$NotFoundException: Resource ID #0x0

Specifically this:

01-13 14:57:39.264: E/AndroidRuntime(12402):    at com.g171.zaloeil.Vue3D.initScene(Vue3D.java:25)

Vue3D.java:25 is your problem (line 25). You’re referencing a resource (R.id.xxxx) that doesn’t exist in your project.
