We take a point on the geometry — the centroid — compute the value for that point on the space filling curve, and store the result in an additional column.
我们在几何图形上取一个点,即形心点,计算那个点在空间填充曲线上的值,并将结果存储在一个附加的列中。

Now we can create an additional function that will combine the before mentioned functions and produce the scalar value on the space filling z-curve for any given geometry.
This paper describes the mathematics base of algebraic geometry and ECC. It also discusses the elliptic curve discrete logarithm problem (ECDLP) and the security applications of ECC on E-commerce.
