How Do I Switch Renderers?

The code below causes a RendererChangeException--what's the proper way to display for awhile in P2D, and then in the default renderer?

int phase = 1;
public void setup(){
size(200,300,P2D);
}
public void draw(){
if(phase == 1 && frameCount > 100 ) {
setupPhaseTwo();
phase = 2;
//draw something in P2D here
} else if (phase == 2) {
//draw soemthing in default renderer here
}
}
void setupPhaseTwo(){
size(200,300);
}

I wonder why you don't stick in the P2D mode?

Anyway, perhaps you can use off-screen graphics (PGraphics) to do this.

I am also interested in whether this is something possible, but I have feeling processing can't really accomplish this.

I was thinking that KeyStone library source may have some solutions to how to switch renderers, but just very beginning of the source tells that it doesn't work with Java2D.

Seems like there's no possibility to switch renderers (unless there's some really dirty hack).

Probably if you want to render 3D and later 2D, then you have to init your P3D and later just draw your 2d graphics into some texture and later apply this texture to some rectangle which is close to camera position, thus creating illusion of 2d. But I am no expert in 3D or opengl.
