A new BGraphics object is what you need. This has been dealt with elsewhere. Do a BGraphics search of the forum.
Here's some code to start off with:
BGraphics gBuffer;
void setup()
{
size(200,200);
gBuffer = new BGraphics( width, height);
}
void loop()
{
gBuffer.background(0);
image(gBuffer,0,0, 200,200);
gBuffer.rect(50,50,100,100);
}
