What you need to do, is after you've done all your 3D stuff, do camera(); then if you're using P3D:

Code:

for(int i=0;i<((PGraphics3D)g).zbuffer.length;i++)
((PGraphics3D)g).zbuffer[i]=MAX_FLOAT; 

or OpenGL:
Code:

//at the top of the sketch
import javax.media.opengl.*;

//then in draw after you've done the 3D stuff.
GL gl=((PGraphicsOpenGL)g).gl;
gl.glClear(GL.GL_DEPTH_BUFFER_BIT); 

This will reset the internals of the scene so that you can draw 2D as normal.

I tried something else and it just worked , I'm posting it just in case other people have the same problem:

void draw ()
{
// this is the moving camera to view in 3D
camera(transX, transY, transZ, 50.0, 50.0, 0.0, 0.0, 1.0, 0.0);

// method that I implemented responsible for the 3D drawing
draw3D_Scene();

// this resets the camera so I can draw in 2D
camera();

// this method is resonpsible of drawing the 2D buttons
drawButtons();
}


but thanks anyway

Hi !
I need to put some 2D elements like buttons in a sketch where everything else is in 3D. I did like Salam, it works, however my texts (controlP5 labels and buttons, same for interfascia) are blurry. I don't understand why, any clue ?
