说明书
摘要:三维、四维 曲面绘图工具。
版本:1.3
-----------------------------------------------------------------------------
用法:(控制台窗口输入命令)

    fp3.exe [曲面函数表达式] [取值半径] [观察距离]

-----------------------------------------------------------------------------
控制:
    A、D    按键控制图像 左右旋转
    W、S    按键控制图像 上下旋转
    Q、E    按键控制图像 Z轴倾斜

    Z、X    按键控制图像 缩放
    O、P    按键控制图像 z轴伸缩

    R       按键重置图像,复位键
    空格键  控制图像 暂停、旋转
    回车键  控制程序 关闭

-----------------------------------------------------------------------------
坐标:
    fp3 "z(x,y)=x+y                    直角坐标示例
    fp3 "r(z,v)=sqrt(arccos(z))+v"     柱坐标示例 ( v为 此刻位置矢量r 投影到xOy平面与x轴的到角,z 为高度 )
    fp3 "r(u,v)=5"                     球坐标示例 ( v为 此刻位置矢量r 投影到xOy平面与x轴的到角,u 为位置矢量r与z轴夹角 )
    fp3 "o(i,j)=i-j,j+2,exp(j)"        xyz分量参数坐标( 用参数i,j去表示xyz三分量值,即 "o(i,j)=x(i,j),y(i,j),z(i,j)" )
    fp3 "z(x,y)=sqrt(4-x^2-y^2/t)"     引入时间 t 的四维坐标 ( 时间参数 t 可以出现在任何坐标体系中,构成四维时空函数)

-----------------------------------------------------------------------------
示例:
    fp3.exe  "sqrt(4-x^2-y^2)"  5  2
   
    绘制半球面z(x,y) = sqrt(4-x^2-y^2),其中x,y的取值半径为5(即-5<x<5, -5<y<5)
    在离原点2单位长度的地方观察半球面。
   
    [观察半径],[观察距离] 也可省略,用 fp3.exe "sqrt(4-x^2-y^2)" 可直接绘制。
