        <id labels="VARIABLE" xml:space="preserve">curve</id>
        <boundVars>
          <id labels="VARIABLE" xml:space="preserve">a</id>
        </boundVars>
      </function>
      <matrix rows="3" cols="1">

CreateSpace 返回介于 a0 和 a1 之间的 20 个点。这些点连接在一起形成 3D 曲线

单个参数的三个函数

1. 以球坐标为半径、水平角度和垂直角定义三个单独的函数。

2. 定义绘制的点数。

3. 使用 CreateSpace 定义曲线。将 sph2xyz 作为最后一个自变量添加。这是用于将球坐标映射为 XYZ 坐标的内置函数。然后可在常规 3D 绘图上绘制球坐标。
