Google新推出的功能，只要在Google的搜索框中输入一个二元方程，就能将这个方程显示在三维空间中，可以用鼠标自由转动翻看三维图形。由于用的是WebGL技术，所以需要支持WebGL的浏览器（如Firefox，Chrome，Safari）

 

前三个是我尝试修改网上的公式得到的效果。

之后是网上搜集的公式尝试后的效果

后记是再自己摸索着尝试的一些公式。 

(-sqrt(1-x^2-(y-abs(x))^2)), x is from -1 to 1, y is from -1 to 1.5, z is from -1 to 1

 

 

(-sqrt(1-x^2-(y-abs(x))^2))+(-sqrt(1-x^2-(y-abs(x))^2)), x is from -1 to 1, y is from -1 to 1.5, z is from -1 to 1

 

 

 

 

(-sqrt(1-x^2-(y-abs(x))^2))+x^2, x is from -1 to 1, y is from -1 to 1.5, z is from -1 to 1

 

 

 

 

 

 

(-sqrt(1-x^2-(y-abs(x))^2))*cos(30*((1-x^2-(y-abs(x))^2))), x is from -1 to 1, y is from -1 to 1.5, z is from -1 to 1

 

 

tanh(y(y^4+5x^4-10(x^2)(y^2))/(x^2+y^2)^4)

 

 

 

sqrt(x*y+y*y)+3*sin(sqrt(x*x+y*y))+5 from -20 to 20

 

 

 

100-3/(sqrt(x^2+y^2))+sin(sqrt(x^2+y^2)), x is from -10 to 10, y is from -10 to 10, z is from 85 to 101

 

100-3/sqrt(x^2+y^2)+sin(sqrt(x^2+y^2))+sqrt(200-x^2+y^2+10*sin(x)+10*sin(y))/1000, x is from -15 to 15, y is from -15 to 15z is from 90 to 101

 

 

 

100-3/sqrt(x^2+y^2)+sin(sqrt(x^2+y^2))+sqrt(200-x^2-y^2+10*sin(x)+10*sin(y))/1000, x is from -15 to 15, y is from -15 to 15z is from 90 to 101

sin(5.5x)*cos(5*y)+x*x+1 x is from -1 to 1, y is from -1 to 1, z is from 0.1 to 2.8

 

(x^2+((3 y)/2-(x^2+abs(x)-6)/(x^2+abs(x)+2))^2)-36

 

 

 

后记：

 

试验x^2+y^2

 

得到:

 

 

试验

1/(x^2+y^2)

 

得到

 

两个叠加，试验

x^2+y^2+1/(x^2+y^2)

得到

 

 

放大，只显示-1，1  区间，试验

x^2+y^2+1/(x^2+y^2), x is from -1 to 1, y is from -1 to 1

 

得到

 

 

将分母增加些函数运算，试验

x^2+y^2+1/sqrt(x^2+y^2), x is from -1 to 1, y is from -1 to 1

得到
