c#winform绘制的立方体方法，时间关系没做成控件，大家在界面上拖一个picturebox即可调用方法即可

 //绘制立方体         public void drawVolume(PictureBox picbox,double sc)  //sc立方体占用的体积         {             mybitmap = new Bitmap(picbox.Width, picbox.Height);//设定位图大小             Graphics g = Graphics.FromImage(mybitmap);//从位图上获取画布             g.Clear(Color.White);//用背景色刷新             //pictureBox1填充为白色，便于显示图像             Rectangle rect = new Rectangle(0, 0, picbox.Width, picbox.Height);
