Smooth path in canvas

Ich spiel grad mit <canvas> rum und wollte eine Kurve möglichst fließend durch Punkte führen:

/images/posts/0000/2068/smooth_path_explanation_big.png

Viele Algorithmen laufen entweder nicht durch jeden Punkt oder setzen voraus, dass man die Pixel selbst malen will, was gerade bei Anti-Aliasing recht mühselig wird. Ich fand dann einen netten Algorithmus von Jean-Yves Quéinec, der Bézier-Splines so hinbiegt, dass eine durchgehende schöne Kurve entsteht. Manchmal gibts noch leicht merkwürdige Kurventeile aber insgesamt funktioniert es gut.

Der Code: smooth_path.js

Die Funktion bekommt ein Array von Punkten und erstellt einen Pfad, den man dann selbst malen kann.

  • path - Ein Punkte-Array der Form [{x:0, y:0}, {x:10, y:10}, ...]

  • smoothness - Der Grad der Biegung. 0 glättet nichts, 1.05 macht aus einem Quadrat einen Kreis und auch sonst schöne Kurven, alles andere erzeugt lustige Formen.

  • joinPath - Falls true werden die Kurven am Anfang und Ende des Pfades aufeinander ausgerichtet, sodass eine durchgehende Form entsteht, wenn Anfangs- und Endpunkt aufeinander liegen.

  • c - der canvas-Kontext

Wer Fehler findet oder Verbesserungen hat, immer her damit :)

Beispiel:

var canvas = document.getElementById('canvas');
var c = canvas.getContext('2d');
var path = [{x: 100, y: 100}, {x: 20, y: 150}, {x: 200, y: 200}, {x: 100, y: 100}];
var smoothness = 1.05;
var joinPath = true;
c.beginPath();
smoothPath(path, smoothness, joinPath, c);
c.stroke();
c.closePath();

Und eine kleine Demo. Per Maus die Punkte setzen, mit dem Slider die smoothness verändern.

List of unusual deaths

1814: London Beer Flood, 9 people were killed when 323,000 imperial gallons (1 468 000 L) of beer in the Meux and Company Brewery burst out of their vats and gushed into the streets.

1919: In the Boston Molasses Disaster, 21 people were killed and 150 were injured when a tank containing as much as 2,300,000 US gal (8 700 000 L) of molasses exploded, sending a wave traveling at approximately 35 mph (56 km/h) through part of Boston, Massachusetts.

2008: Gerald Mellin, a U.K. businessman, committed suicide by tying one end of a rope around his neck and the other to a tree. He then hopped into his Aston Martin DB7 and drove down a main road in Swansea until the rope decapitated him. He supposedly did this as an act of revenge against his ex-wife for leaving him.

2009: Martin Cassidy, a 44-year-old stand-up comedian from Blackburn, England, died from asphyxia caused by breathing in large quantities of laughing gas while watching pornography on his laptop computer, according to a coroner. The coroner ruled a case of "Death by misadventure".
