Generate points based on functions by Processing
使用Processing基于多个函数生成点
Processing setting origin point at top left by default
In this project I changed it to the bottom left by flip Y axis
you can see this in code
Processing默认将原点设置在左上角
这个项目里我把Y轴翻转了，于是原点变为左下
详见代码
The first function based on distance to the original point
More close to the origin, random points more likely to be generated
第一个函数基于到原点的距离
距离原点越近，随机点越有可能被生成并显示出来
The first function based on distance to the diagonal line
More close to the diagonal, random points more likely to be generated
第二个函数基于到对角线的距离
距离对角线越近，随机点越有可能被生成并显示出来
The second function has a slope which could be modify
When slope set to 1, it means diagonal line
因为是到直线的距离，所以直线的斜率可以改变，我在代码里面把它单拎出来了
将slope设置为1的时候表示对角线
Functions could be combined, and amount of points could be controlled easily
I use probability to control weight of each function
It can be changed by multiply a number such as 0.5
And will casue half weight of that function
After change weight, the threshold should be changed
You can find detailed comment in the project file
Hopes that can help
多个函数可以组合起来，每个函数的生成权重使用单独的probability来控制
如果乘以一个数（例如0.5，权重减半）就可以直接改变特定函数的权重
之后适当更改阈值threshold就可以了
