利用HTML5绘制点线面组成的3D图形的示例

cube = new Cube(80); cube._initVector();

function initAnimate(){ cube._draw();

animate();

}

function animate(){ ctx.clearRect(0,0,canvas.width,canvas.height)

rotateY(cube.vectors);

rotateX(cube.vectors); cube._draw();

if("requestAnimationFrame" in window){ requestAnimationFrame(animate);

} else if("webkitRequestAnimationFrame" in window){

webkitRequestAnimationFrame(animate); }

else if("msRequestAnimationFrame" in window){ msRequestAnimationFrame(animate);

} else if("mozRequestAnimationFrame" in window){

mozRequestAnimationFrame(animate); }
