How to draw a 3D sphere in HTML5?
To create a 3D sphere, use the HTML5 canvas. You can use the following function in your code:
function display(r) {
this.point = new Array();
this.color = "blue)"
this.r = (typeof(r) == "undefined") ? 20.0 : r;
this.r = (typeof(r) != "number") ? 20.0 : r;
this.vertexes = 0;
for(alpha = 0; alpha <= 6.28; alpha += 0.17) {
p = this.point[this. vertexes] = new Point3D();
p.x = Math.cos(alpha) * this.r;
p.y = 0;
p.z = Math.sin(alpha) * this.r;
this.vertexes ++;
}
}
