Support / Does jPCT-AE support shadow?
« on: August 01, 2012, 08:36:40 am »
There is a ShadowHelper  class in jPCT but not in jPCT-AE.

I want to use shadow in my world with jPCT-AE, is there any simple way to do this?

Thanks!

 > set texture and use lighting

Does the material decide how a model looks like in the lighting(s)? 

What's the difference between a model with texture only and a model with both texture and material?

Do animated3D objects have default material?

Thanks!

So,  there is no way to use material for Animated3D objects. Is that right?

Without material and lighting, my dog seems not good, could you give me any advices?

OgreMax exported the .material.xml,  but how to use it?

Is .bones including the material info?

« on: July 30, 2012, 03:07:55 pm »

Everything was ok when  my code like this:

 
Code: [Select]
Texture dogTexture = new Texture(mResources.openRawResource(R.raw.dog));  //the same texture-res
      Texture worldTexture = new Texture(mResources.openRawResource(R.raw.dog));    //the same texture-res
      Texture skyTexture = new Texture(mResources.openRawResource(R.raw.dog));       //the same texture-res

      TextureManager.getInstance().addTexture("dog", dogTexture);
      TextureManager.getInstance().addTexture("sky", dogTexture);
      TextureManager.getInstance().addTexture("world", worldTexture);
 
But crashed when i changed the codes to:

 
Code: [Select]
Texture dogTexture = new Texture(mResources.openRawResource(R.raw.dog));
      Texture worldTexture = new Texture(mResources.openRawResource(R.raw.dog));
      Texture skyTexture = new Texture(mResources.openRawResource(R.raw.dog));

      TextureManager.getInstance().addTexture("dog", dogTexture);
      TextureManager.getInstance().addTexture("sky", skyTexture);       //modified here
      TextureManager.getInstance().addTexture("world", worldTexture);

res/raw/dog is a 512*512 jpg. Crash info:

Bones / How to improve the performance of animation?
« on: July 29, 2012, 02:13:47 pm »
My dog has 10364 triangles.

On my phone, the static-dog-fps is about 60, that's not bad, but when played the skin-animation, the fps dropped to only 6 fps, it seemed to be rather slow.

I have refered to jpct-ae-wiki-"Performance tips for Android", but seemed to be little help with my situation.

So, are there any advices to improve the performance of animation without reducing the faces of dog-model?

I am a beginner of 3D-graphics, so i want to know why an animating-object is much slower than the static one? What's the hotspot? And how to resolve it? I have tried to do the profiling with android-ADT,  and seemed like that the applySkeletonPose() cost the most cpu-time. I don't know if the bones-animation used the gpu(or other graphic-hardware) power, and how to profile this.  And how the hardware of a phone affect the performance, which is the most important factor： cpu、ram、gpu or others?

Thanks!

And my code is rather simple:
    Load an .bones animated-object, set AmbientLight, then play skin-animation.

There is almost little difference of the performance  between opengles-1.X and opengles-2.0 with my simple project.

Bones / Re: OgreMax Merging Meshes -> export -> failed to convert to .bones
« on: July 29, 2012, 09:05:55 am »
Good job! Thanks!

But where should i download the latest version?

I tried this: http://aptalkarga.com/bones/#download

But i compared the latest(downloaded) version with the old one, they are just the same. And there is no methond: AnimatedGroup.setVisibility(..) in the latest version.

Another question:

I watched the bones-update-history: many error was caused by jme-2.1.  I don't know if can use jme-3.0 to instead of jme-2.1.

And i want to use Ogre-XML(converted to some compacted binary format like .bones)  as my only model-format(both static and animated). But the convert-bones-script doesn't  work when there is no animation-info in ogre-xml.  Can you add some classes or methods to support this? And can you support Morph-animation and .scene-loading?

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();

Bones / Animation seems strange
« 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.

Bones / Proplem with blending pose-animation and skin-animation.
« on: July 25, 2012, 09:53:48 am »
My scene:
 1, Objcets: a rock + a dog
 2, Animations: rock-skin + dog-skin + dog-pose

I want to play all animations at the same time, my codes:

Code: [Select]
           //AnimatedGroup group
            group.animatePose(index, mAnimationIndex);             //dog-pose
            group.animateSkin(index, mAnimationIndex);              //dog-skin
            group.animateSkin(index, mAnimationIndex + 1);        //rock-skin
            group.applyAnimation();
When it run, just play rock-skin and dog-skin, dog-pose didn't be played. But if i changed my code like this(change order):


Code: [Select]
   group.animateSkin(index, mAnimationIndex);          //dog-skin
            group.animatePose(index, mAnimationIndex);         //dong-pose
            group.animateSkin(index, mAnimationIndex + 1);    //rock-skin
            group.applyAnimation();
Rock-skin 、dog-skin、dog-pose are all played.


And if:

 
Code: [Select]
   group.animateSkin(index, mAnimationIndex);          //dog-skin
            group.animateSkin(index, mAnimationIndex + 1);       //rock-skin
            group.animatePose(index, mAnimationIndex);           //dog-pose
            group.applyAnimation();
Dog-pose was played, and rock-skin seems to be played too, but rock-skin was rather different from what seen in maya.

Any advices?
