hi raft :

i want to implement a feature .
when i touch the object with loop animation-1 , the object must have some respond ( do  another animation-2 ) , and then come back to the original animation-1 after the animation-2 is finished.

how to do that ? i know how to change the animation with model using :
group.animateSkin(index, animationID);

but i do not know how to handle the time of the animation, or does Bones have some simple ways to deal with it ??

hi  raft :

now i can create some simple model ( teapot , cube and et al ..  ), add some bones and animated  and export to .bones , and then render via bones successfully.

however, when i render some complex model ( or download from the internet  ), the result is : the screen shows nothing.
oppositely , i can export this model into obj and render via jPCT-AE successfully.

i am sure the "Steps of .Bones Export" is correctly and the code is ran  certainly according the logcat


so , do you meet such bug or may be the Bones could no render some complex model with animation ?

hi raft :
now i uses the blender to make a model with animation and export to body.skeleton.xml and body.mesh.xml.

body.skeleton.xml just including only one animation :
<animations >
 <animation name="my_animation" length="1.0833333333333333" >

      <tracks >

        <track bone="root" >

          <keyframes >

            <keyframe time="0.0" >

              <translate z="0.000000" x="0.000000" y="0.000000" />
      ......
      ...
      .
 </animation>
</animations >
and then transfer to body.bones via cmd and load it via Bones , as the code shown belown.

   animation =  1;
     
   if (animation > 0 && masterNinja.getSkinClipSequence().getSize() >= animation) {
      float clipTime = masterNinja.getSkinClipSequence().getClip(animation-1).getTime();
      if (animateSeconds > clipTime) {
         animateSeconds = 0;
      }
      float index = animateSeconds / clipTime;
      if (false) {
         for (AnimatedGroup group : ninjas) {
            for (Animated3D a : group)
               a.animate(index, animation);
         }
      } else {
         for (AnimatedGroup group : ninjas) {
            group.animateSkin(index, animation);

         }
      }
         
   } else {
      animateSeconds = 0f;
   }
however, when i loading  such model and the demo crash and the error output:

hi raft:

Question1:

• [size=78%]what is the format of nijia.group.bones ?[/size]
• [/size][size=78%]how to open it ?[/size]
• [/size][size=78%]how to make the model and export to such file ?[/size]

Question2:
i try to copy the cylinder.group.bone & stone.jpg from "Bones/res/raw/" to" Bones-Android-Ninjia/res/raw/"
but the error was outputed as follown:

Hi raft :

the model can be rendering according to you support .

However , the model can not be rendered in correct position ( the rotation is no right , as shown as attached)

case 1 : using the function : model.rotateXYZ(float r) : result : the model could no be in correct angle , some time the model  even missing ;
case 2 : the matrix output from ARToolkit is correct Definitely , because i have verified via rendering a cube through OpenGL ES ;
case 3 : such bug still exists in JPCT-AE;

but i still do not know how to do. so  do you have some idea about it ?

the code was shown as belown:

public void onDrawFrame(GL10 unused) {
//...
Matrix projMatrix = new Matrix();
projMatrix.setDump(ARNativeActivity.getProjectM());
projMatrix.transformToGL();
SimpleVector translation = projMatrix.getTranslation();
SimpleVector dir = projMatrix.getZAxis();
SimpleVector up = projMatrix.getYAxis();
cameraController.setPosition(translation);
cameraController.setOrientation(dir, up);
//...
for (Animated3D a : group) {
a.animate(index, animation);
Matrix dump = new Matrix();
dump.setDump(ARNativeActivity.getTransformationM());
dump.transformToGL();
a.clearTranslation();
a.translate(dump.getTranslation());
a.setRotationMatrix(dump);
Log.i("jpct_test", "runing in loop 2");
}
//...
world.renderScene(frameBuffer);
world.draw(frameBuffer);
frameBuffer.display();
}


Hi raft :

i got some error when inject the Bones Project into my Project but some error was shown as below:

i think it should be the Problem  of Import , but  i have set the Java Build Project to Bones already, so what't i need to do ??

Dear Master :

Purpose :
i need to set a  [ real-time matrix ] for the obj to realize the AR ;

as the normally, i can use the "fucntion GLES20.glUniformMatrix4fv" to set a matrix to the shader , and then calculate the right position of the model on the screen;

i can get the translate matrix output by ARToolkit in real-time ;
 but  i do not know how to set the matrix when i use the jpct-ae to rendering.
i have tried to use the "jpct-ae-fucniton model.setTranslationMatrix(mat);" , but all the result  for scale , position and direction  are wrong.


question : how to use the translationmatrix in jpct as will as GLES20function::GLES20.glUniformMatrix4fv??

follow the help from EgonOlsen , i have loading a md2 model on the preview data.

However, the texture of the model have been changed and overwrited by the preview buffer texture grab of camera. Pls find  the attached , shown such case
 so , how can i change the textureID manually or have another way to fix such issue .
