Lines draw incorrectly in PGraphics? May 31st, 2010, 8:28pm   When I run the code below I get differently capped lines, although it seems they should be the same: Quote: PGraphics pg; int res = 600; void setup () {   size(res,res);   pg = createGraphics(res,res,P2D); } void draw() {   strokeWeight(50);   stroke(0);   strokeCap(ROUND);   line(400,200,200,400);   pg.beginDraw();   pg.strokeWeight(50);   pg.stroke(100);   pg.strokeCap(ROUND);   pg.line(200,200,400,400);   image(pg,0,0);   pg.endDraw(); } Is this a known issue? thanks, colin

Please, read the stickies at the top of each forum section! Don't post in the Software Bugs section, even less if you are not sure that's a bug in Processing itself.

And note that you compare two different drawing modes: default (JAVA2D) and P3D! Now, if you take time to read the reference page of strokeCap(), you would see: Quote: This function is not available with the P2D, P3D, or OPENGL renderers So, to answer your question, it is a known limitation...
