I wanna place an object at the bottom right corner of world with the following code, it doesn't work.

How to place object at specific location of world?

Texture waterMarkTexture = new Texture(BitmapHelper.rescale(BitmapHelper.convert(context.getResources().getDrawable(R.drawable.logo_camino_white)), 128, 128));
      boolean isWaterMarkTextureAdded = TextureManager.getInstance().containsTexture("watermark");
      if (!isWaterMarkTextureAdded) {
        TextureManager.getInstance().addTexture("watermark", waterMarkTexture);
      }
      Object3D waterMarkModel = Primitives.getPlane(1, AppUtils.dp2px(context, 4));
      waterMarkModel.setTexture("watermark");
      int screenX = AppUtils.getScreenWidthPixels(context) - 20;
      SimpleVector position = Interact2D.reproject2D3DWS(world.getCamera(), frameBuffer, screenX, screenX);
      waterMarkModel.setOrigin(position);
      waterMarkModel.build();
      world.addObject(waterMarkModel);


The watermark (orange icon) is a square image, but you see that it is stretched. The device's screen resolution is 2560x1440.

Also, seems there is some jaggies at bottom right corner of watermark.

Has any idea?

because typically exporters do not export skeleton without animation. no skeleton -> no programatic animation

Actually i have no idea what the animation defined in .dae file is about. My model is a human head, and i want to programatically animate the mouth based on facial landmarks detected. If i put a dummy animation in my .dae file, is the function of dummy animation only make exportation (.dae -> bones) works?

In my .dae file, it defines some texture file paths like

How can i tell .bone where my texture are?

Thanks raft. I will try and get back to you.

Also I saw a sample that uses .bone file format, is it faster in terms of loading the model? Is it similar with the serialization object format in jpct-ae? How can I covert my .dae file to .bone?

Does bone support .obj format?

Sorry, too many questions. Thanks.

I'm also worry about the performance of further processing. Do you have another better approach?

Which device are we talking about here?

LG-D858

Why are you still mixing jPCT-AE and GL calls?

It is because I only found this way to render camera texture to the GLSurfaceView. Is there are method like "addStreamingBackground()" in jPCT-AE?

clearZBufferOnlythis works!!
