Hello,

I want the following program to be able to draw in an offscreen buffer. I'm using PGraphics with the library 3D, as the PGraphics help file mentions that the 2D is not fully implemented (devs: is this  going to be available soon?).

Anyway, my question is: why can't I change the width of strokes when I draw on a PGraphics object?

Please run the example to reproduce this.

I suppose the answer is "not yet implemented". In which case I would like to know if there is a way of using an offscreen buffer in order to avoid redrawing the whole surface.

Thanks,

Jean-Baptiste

PGraphics pg;

void setup() {
 size(800, 800);
 pg = createGraphics(1600, 800, P3D);
}

void draw() {
 

if (mousePressed)
{
 
/*  // remove the '/*' comments to see the difference
 stroke(255);
 strokeWeight(3);
 beginShape();
 curveVertex(pmouseX, pmouseY);
 curveVertex(pmouseX, pmouseY);
 curveVertex(mouseX, mouseY);
 curveVertex(mouseX, mouseY);  
 endShape();

*/
 pg.beginDraw();

  pg.stroke(255);
  pg.strokeWeight(3);

 pg.beginShape();
 pg.curveVertex(pmouseX, pmouseY);
 pg.curveVertex(pmouseX, pmouseY);
 pg.curveVertex(mouseX, mouseY);
 pg.curveVertex(mouseX, mouseY);  
 pg.endShape();

 pg.endDraw();

 image(pg, 0, 0);
}


}

If you don't specifically need 3D, use JAVA2D instead of P3D in your createGraphics. That 2D renderer does work and do strokeWeight, it's P2D that's incomplete.
