用minscript脚本语言实现数学函数曲线编辑器

这是一款数学函数曲线编辑器，c++开发，函数解析使用了自己开发的脚本语言minscript。

编辑器支持以下类型的函数曲线。
    MT_Normal     ,//一般方程 
    MT_Implicit   ,//参数方程 
    MT_Polar      ,//极坐标方程 
    MT_UVsurface  ,//uv曲面
    MT_Programable,//可编程

每种曲线类型都可以带动画，只需要勾选动画选项，然后在函数公式中引入变量time。
可以通过数学函数设置曲线颜色。

可以设置自变量的作用域，动画的时间范围等。
可编程效果可以自定义变量，使用预置的绘图函数。

数学函数曲线编辑器（可带动画）

这个编辑器中隐藏着一个用mincsript脚本语言编写的测试小游戏，引擎将c++实现的渲染及输入等接口绑定到了mincsript脚本语言，由脚本语言编写游戏逻辑。要运行游戏 修改data\script\startup.script文件为 
ExecFile("data/script/test_game.script"); 即可。

测试游戏脚本：
