Title: Animation seems strange
Post by: kiffa on July 27, 2012, 07:02:48 am

Maya2012 + OgreMax

First i made an dog-animation "run without position-moving"(which means the dog just run in situ). The animation played fine on my phone.

Then i changed the animation to "run with position-moving"(which means the dog run here and there). The .mesh and .skeleton runs fine in OgreMax-WinViewer. But when i played it on my phone(with .bones), something seemed to be strange:
 
  The dog's body moved, but the tail didn't move with the body. The tail seemed to stretched from origin position to where the dog's body moved to.

I tried jme3 with the same .mesh.xml and .skeleton.xml , evething was ok.

Shall i send the xml-file to you?

I will try .xml instead of .bones.

that's strange and shouldn't happen. can you please double check if it seems ok in OgreMax viewer and has a problem in Bones?

.xml or .bones shouldn't differ. .bones format is created by first laoding xml files.

I have checked again. The same mesh+skeleton played fine in OgreMax-WinViewer, but strange on phone with .bones(tail stretched). I am not sure how to use .xml instead of .bones, so i don't know if the result are some difference between them.  Could you do a test with my .xml? This problem bore me a long time. Thanks!

Here are my codes:

     

Code: [Select]

  //onSurfaceCreated
         AnimatedGroup group = BonesIO.loadGroup(mContext.getAssets().open("dog21.bones"));
        mGroup = group;
        for(Animated3D a : group)
        {
          a.setTexture("world");
          a.build();
        }
        mDog = group.get(0);
         group.addToWorld(mWorld);
      Camera camera = mWorld.getCamera();
      camera.setPosition(0, 0, 150);
      camera.lookAt(mDog.getTransformedCenter());
      camera.rotateCameraZ((float) Math.PI);
      mWorld.buildAllObjects();

      mFrameBuffer = new FrameBuffer(480, 800);
      MemoryHelper.compact();
       


// onDrawFrame

      mDog.setAutoApplyAnimation(false);
      mDog.animatePose(time_line, animation_index);
      mDog.animateSkin(time_line, animation_index);
      mDog.applyAnimation();

     time_line += 0.05 * speed;

      if(time_line > 1)
        time_line = 0.01f;

      mFrameBuffer.clear();
      mWorld.renderScene(mFrameBuffer);
      mWorld.draw(mFrameBuffer);
      mFrameBuffer.display();

ah you are using animation blending. that may be the cause. send me the files and let me have a look

have a look at OgreSample to see how to load Ogre xml files directly. but that is both slower and requires Ogre3D jars on classpath, that's why .bones format is preferred

Yes, i prefer .bones too.

And i have sent the files to you, thanks!

yes, there is definetely a flaw there. jME shows it correct to. I will investigate it in detail.

can you please provide me some screenshots of your skeleton, just the one below, from a similar perspective

edit:  I need the screenshots in bind pose

..and looking at your skeleton hierarchy, there are two root bones (without a parent): joint1 and joint5. This is uncommon, mostly there is only one root bone (without a parent) I think this may be causing the problem. Reorganize your skeleton that there is only one root bone and see if that helps.

I agree that Bones should handle that and I'll try to fix it.
