I use two triangle to form a square, and use a serial of png picture  to do frame animation.
when animating, some animation make the object edge blinks. I dont know what's the cause .


float[] coord_menu  = {
    0.0f, 0.0f, 0.0f,
    0.0f,10.0f, 0.0f,
    10.0f,10.0f, 0.0f,
    10.0f, 0.0f, 0.0f,
    };
    float[] uvs = {
    0.0f, 0.0f,
    0.0f,1.0f,
    1.0f,1.0f,
    1.0f,0.0f,
    };
    int[] indices = {
    0,1,2,
    2,3,0,   
    };
   
    Object3D menu = new Object3D(coord_menu,uvs,indices,TextureManager.TEXTURE_NOTFOUND);



       I use menu.setTexture() to set a series of texture to make the menu animating, when disable
transparent, the menu's edge blinks, with transparent enable,  the blinking exist also.

after reading the mentioned thread, I found my problem is not using one FrameBuffer in two thread.
the cause is I flush the textureManager in my logic. now I have resolved it. thanks.

hi, I have two  jPCT-AE activity, activity A starts activity B, after back from B to A, some objects
and textures of activity A lost, not show on the screen, what's the problem here ? thanks.

=========== renderer resume code =================

public void onSurfaceChanged(GL10 gl, int width, int height) {
// TODO Auto-generated method stub
if (fb == null) {
Logger.log("==== Launcher launch: " +width+"X" +height);
fb = new FrameBuffer(gl, width, height);
mLauncher.tearDown();
mLauncher.setup();
mLauncher.setFrameBuffer(fb);
mLauncher.setFrameBlitter(new AndroidFrameBlitter(fb));

}else{
fb.dispose();
fb = new FrameBuffer(gl, width, height);

mLauncher.setFrameBuffer(fb);
mLauncher.setFrameBlitter(new AndroidFrameBlitter(fb));
}
}


ps:  activity B starts a normal android ui activity C , and when back from C to B, the objects and texture is ok.
the renderer code is similar.

In jPCT-AE? No, that shouldn't be the case. In desktop jPCT...yes. The format in desktop jPCT is 128*128 + 128+1, but you can completely ignore the last 129 entries. There are used by the software renderer only. But as said, in jPCT-AE, this isn't the case...

oh, yes. it's in desktop jPCT.   I develop my app in desktop,
then use a android wrapper to depoly them to android.

thanks.

what's the exact format of  param  src  in ITextueEffect. apply(int[] dest,  int src[]) ?
I have a  128x128 texture and in apply() , I found src.length is 16513., but 128x128=16384
they are not the same.

Yes. thank you. I just not  use the constructor with useAlpha parameter, now it looks ok.

after setTransparent, my texture seems distorted. see the attachment.
after Object3D.setTransparencyMode(Object3D.TRANSPARENCY_MODE_DEFAULT);
       Object3D.setTransparency(20);  the upper right of the recyclebin looks dirty.
how can I make it look as the same as I view it in picture viewers ?  thanks

no. but for now, they face to the screen on the same side.

I may have 20 3D icon ons the screen, so I am worry about the memory consumption.
but it seem like I should adopt the guide in the wiki.

Actually, I am working on a UI with 3D icon.
said there has three position A,B,C  when the 3D icon move from A to B, it will scale up, and
when it move from B to C , it will scale down, now I am doing moving  by interpolating the matrix between
A,B,C . the moving works fine, and I want scale work this way too.(by interpolate the rotation matrix)

That highly depends on the model and the textures as well as the target platform. My old Galaxy with 1.6 has 16mb VM memory, my Nexus S with 4. 0 has 48mb available.

What's the polygon count of your models and the size of your textures?

Some hints: http://www.jpct.net/wiki/index.php/Reducing_memory_usage

I am wonder if it is possible to use JNI to allocate C memory for use by jPCT or OpenglES call ? the native code will not  limit by VM.

I want making a object scaling when it's moving, I use code
like following, but it seems scale not working.

Matrix posMatrix1 = ..;                                  // source position
Matrix posMatrix2 = ..;                                  // target position
Object3D dummyParent Object3D.createDummyObj();
Object3D son = ... ;
dummyParent.addChild(son);
posMatrix1 = dummyParent.getRotationMatrix().cloneMatrix();

...  do some move and rotate


dummyParent.setScale(2.0f);                    // ======================  scale
posMatrix2 = dummyParent.getRotationMatrix().cloneMatrix();  // will get scale factor in here ?


Matrix m = new Matrix();
m.interpolate(posMatrix1, posMatrix2, delta);
dummyParent.setRotationMatrix(m.cloneMatrix()); // ==============  will scale factor affect the son Object ?



thanks. I will look the link.

thanks. I have tried it. now the icon looks better.

I found dalvik vm's heap memeory is very limited, my app just use some textures and load 2 models,
and the dalvik vm throws OutOfMemoryError exception.
I am doubtl how other people implement 3d game in android, how do you manage the memory ?
