Creating 2-D Animations on Canvas - lotus

This is an impressive animation of a lotus power.

A beautiful animation based on lotus flower:

The parametric equations for the shape take the following form:

• x(t) = (a + b) cost − c cos((a/b + t)t)
• y(t) = (a + b)sin t − c sin((a/b + 1)t)
Finding a good book to master HTML5 can be very challenging: there are so many around - most with eye-catching titles and very complex substance.
Therefore, Vivax Solutions strongly recommends Core HTML5 Canvas for those who really want to delve into HTML5.

The Digitized Lotus

The Code for the animation is as follows:

<script>
var canvas = document.getElementById('Canvas_One');
var context = canvas.getContext('2d');
var i, j = 0.01, t = 0;
var col = new Array('green', 'blue', 'red', 'cyan', 'magenta', 'yellow', 'white');
function timing() {
context.clearRect(0, 0, 400, 400);
for (i = 0; i < 2 * Math.PI; i = i + 0.01) { var x = 200 + (100 * Math.cos(3 * i) + 50 * Math.cos((70) * i / 5));
var y = 200 + (100 * Math.sin(3 * i) + 50 * Math.sin((70) * i / 5));
t = t + 1;
if (t > 6) { t = 0; }
context.beginPath();
context.moveTo(200, 200);
context.arc(x, y, 2, 0, 2 * Math.PI);
context.fillStyle = col[t];
context.fill();
}
}
window.setInterval('timing()', 10);
</script>
