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);
g.FillRectangle(new SolidBrush(Color.WhiteSmoke), rect);
Pen pen = new Pen(Color.White, 2);//画笔
Pen penline = new Pen(Color.White, 1);//画笔
SolidBrush sb = new SolidBrush(Color.FromArgb(92,0,128));//标注画刷
int htmp = 7;

/*
* 下面是立方体框架对于立方体可不画因为会覆盖
g.DrawLine(pen, 20, picbox.Height - 20, (picbox.Width - 5)/2, picbox.Height - 13);//绘制X斜下
g.DrawLine(pen, (picbox.Width - 5) / 2, picbox.Height - 13, picbox.Width - 20, picbox.Height - 20);//绘制X斜上
g.DrawLine(pen, 20, picbox.Height -20, 20, 20);
g.DrawLine(pen, 20, 20, (picbox.Width - 5) / 2, 20 + htmp);
//中间竖线
g.DrawLine(pen, (picbox.Width - 5) / 2, 20 + htmp, (picbox.Width - 5) / 2, picbox.Height - 20+htmp);
g.DrawLine(pen, (picbox.Width - 5) / 2, 20 + htmp, picbox.Width - 20, 20);
g.DrawLine(pen, picbox.Width - 20, 20, picbox.Width - 20, picbox.Height - 20);
//顶斜上
g.DrawLine(pen, 20, 20, (picbox.Width - 5) / 2, 20 - htmp);
//顶斜下
g.DrawLine(pen, picbox.Width - 20, 20, (picbox.Width - 5) / 2, 20 - htmp); //底斜上

//底部斜下
