HTML Canvas 中的原始形状库
是否有任何库可以为原始形状提供一些有限的功能。我尝试使用 EaselJS ，虽然它有一些令人惊奇的特性，但基本形状并不是其中之一。形状内部的测试是通过像素测试进行的，与光线测试等相比，速度非常慢。
我想矩形和圆形使用得最多，我可以为它们两个创建碰撞检测，但是多边形的情况会变得更加复杂。有没有相关的图书馆？我知道 JQuery 有一个，但它似乎是针对 HTML 元素而不是画布
Are there any libraries out there that provide some limited functionality for primitive shapes. I tried getting my feet wet with EaselJS and although it has some amazing properties, basic shapes is not one of them. Tests for inside a shape are carried out by pixel testing which is incredibly slow compared to for example ray testing.
I imagine the rectangle and the circle gets used the most, and I can create collision detection for the two of them, but things get more complicated with polygons. Are there any libraries out there for this? I know JQuery has one, but it seems like it is for HTML elements and not the canvas

您可能想看看 CAKE
或processingjs。我不确定这些是否特别适合您的需求，但它们似乎是目前最发达的画布库。
You might want to take a look at CAKE
or processingjs. I'm not sure if these are particuarly suited to your needs, but they seem the most developed library's for canvas at the moment.
