将剪切变换应用于圆 [英] Apply a shear transform to a circle

问题描述

我正在编写一个程序来创建等距线图，我需要弄清楚如何使用剪切矩阵变换将2D圆转换为椭圆。我已经在谷歌搜索了几天，但似乎无法提出任何代码示例。我使用的数据是中心点和半径。



有人可以指向我的资源吗？

I'm writing a program to create isometric line drawings and I need to figure out how to convert 2D circles to ellipses using a shear matrix transform. I've searched Google for a few days now but can't seem to come up with any code examples. Data I use is centrepoint and radius.

Can someone point me to a resource?

推荐答案

你可以不加修改地保留圆圈（以及其他所有内容）并让图形对象处理通过其转换属性进行剪切。它的类型为 Matrix ，它支持 Shaer 开箱即用。

You can leave the circle (and everything else) unmodified and let the Graphics object deal with shearing via its Transform property. It's of type Matrix, which supports Shaer out of the box.
