最好也是最合理的方法是使用HTML5 Canvas 功能： http://en.wikipedia.org/wiki/Html5_canvas [ ^ ]。



这将需要相当大的努力，但你能做的是令人印象深刻的：

您可以找到几个已经设计过的引擎，特别是用于交互式创建矢量图形的引擎用户：
$ b $bRaphaël： http://raphaeljs.com/ [ ^ ]，

CAKE：http://code.google.com/p/cakejs/ [ ^ ]，

Paper.js，一个矢量图形脚本网络： http：/ /paperjs.org/ [ ^ ]，

Burst Engine： https://github.com/rwaldron/burst-core [ ^ ]。

The best and most reasonable way to do it is to use HTML5 Canvas feature: http://en.wikipedia.org/wiki/Html5_canvas[^].

It will take considerable effort, but what you can do is quite impressive:
http://net.tutsplus.com/articles/web-roundups/21-ridiculously-impressive-html5-canvas-experiments/[^].

You can find several engines already designed, in particular, for creation of vector graphics interactively by the user:
Raphaël: http://raphaeljs.com/[^],
CAKE: http://code.google.com/p/cakejs/[^],
Paper.js, a vector-graphics scripting network: http://paperjs.org/[^],
Burst Engine: https://github.com/rwaldron/burst-core[^].
