Canvas Timer JavaScript Paint uses Canvas APIs

Physics engine with Canvas Timer 1) clear canvas Paint 2) physics iteration 3) draw shapes Box2D physics engine

function createBall(world, x, y) { var ballSd = new b2CircleDef(); ballSd.density = 0.3; ballSd.radius = 20+Math.random()*20; ballSd.restitution = 0.1; ballSd.friction = 0.2; var ballBd = new b2BodyDef(); ballBd.rotation = 0.3; ballBd.AddShape(ballSd); ballBd.position.Set(x,y); return world.CreateBody(ballBd); }

world.Step(ms,1);

3) draw shapes box2d objects/ positions canvas

Vector graphics SVG + VML JavaScript Reﬂow Rendering Paint creates vector graphics nodes
