clear with alpha???But how???
Thats what I want to know....
do you mean this???
Code: [Select]

RGBColor transp = new RGBColor(67,123,245,0);
fb.clear(transp );
world.renderScene(fb);
world.draw(fb);
fb.display();
But I am not getting the proper result..

Sorry sir :)
Next time it would be happened...
But Sir I am not able to find the transparent background yet...
I think In the World class there should be a function that make the background transparent...
There is a Example in APIDemo of Android for transparent background.
Plz Update it and Upload the  JPCT-AE....Just like u did for pick 3d object into 2d co-ordinate
Thanks in advance....

still it does not work perfectly

I did this
Code: [Select]

//SimpleVector position = new SimpleVector(Interact2D.reproject2D3DWS(world.getCamera(), fb, (int) x,(int) y));
SimpleVector position = new SimpleVector(Interact2D.reproject2D3D(world.getCamera(), fb, (int)x,(int)y, 10.f));
   
   position.matMul(world.getCamera().getBack().invert3x3());
   position.add(world.getCamera().getPosition());
   
   Object[] result = world.calcMinDistanceAndObject3D(world.getCamera().getPosition(), position, .01F);

but the problem is it always returns the object which is neat from camera

I have also used reproject2D3DWS(..) to same thing happened
any idea how can we do this??

Sir
Actually I am no getting you....Would you please explain how can i Clear with alpha(!) ???

Do u mean this??
Code: [Select]
RGBColor transp = new RGBColor(0,0,0,0);
//fb.clear();
fb.clear(transp);
world.renderScene(fb);
world.draw(fb);
//fb.blit(fb.getPixels(), this.widht, this.height, 0, 0, this.widht, this.height, this.widht, this.height, true);

EgonOlsen Thanks for your reply...
But still I am not able to make transparent background :'(
I will be very glad if you fix my problem.....

Into the onDrawFrame function I have Written the following code

fb.clear();
world.renderScene(fb);
world.draw(fb);
fb.blit(fb.getPixels(), this.widht, this.height, 0, 0, this.widht, this.height, this.widht, this.height, true);
blitNumber(lfps, 5, 5);
fb.display();

still I am not able to find any solution...

My total code is

Is it possible Android Camera and JPCT-AE as a render that overlays the camera???
I don't think so.When I initialize

World world = new World();

it render a black screen itself...
I haven't seen any function function in World class that I can change it black color to make it transparent.
There is function in FrameBuffer Class
public void blit(int[] src,....... ,boolean transparent)

by this I can have the transparent background....But the problem I am facing that is how can i get the first parameter of this function the current renderer texture??
