bh画线算法

❶ 什么是bh algorithm

bh algorithm是

BH算法

❷ C语言基础问题,画三角形

你描述的输入不清，我调整了一下。

其实最重要是分解程序编程一个一个操作。

首先要闹昌羡有个画板，

然后液拍程序能画线，

最后对三角形填充。

就是这么简单，三种操作。

先来个短的代码：

#include<stdio.h>
#include<math.h>
#include<string.h>
usingnamespacestd;
constintbsize=64;//最大画板大小
constdoubleeps=1e-6;//精度控制
charboard[bsize][bsize];//画板
intbw,bh;//画板宽高
intmain()
{
	voidprintBoard();//输出画板内容

	intiw,ih;
	doublex[3],y[3];
	doublev0x,v0y,v1x,v1y,v2x,v2y;
	doubled00,d01,d11,d20,d21,denom,v,u,w;

	scanf("%d%d",&ih,&iw);
	bw=iw+2;//你边缘多出了边框,所以+2
	bh=ih+2;
	scanf("%lf%lf%lf%lf%lf%lf",x,y,x+1,y+1,x+2,y+2);
	//清空画板
	for(inti=0;i<bh;i++)
		for(intj=0;j<bw;j++)
			board[i][j]='';
	//利用质心坐标求值
	v0x=x[1]-x[0],v0y=y[1]-y[0];
	v1x=x[2]-x[0],v1y=y[2]-y[0];
	for(inti=0;i<bh;i++)
		for(intj=0;迅销j<bw;j++)
		{
			v2x=i-x[0],v2y=j-y[0];
			d00=v0x*v0x+v0y*v0y;
			d01=v0x*v1x+v0y*v1y;
			d11=v1x*v1x+v1y*v1y;
			d20=v2x*v0x+v2y*v0y;
			d21=v2x*v1x+v2y*v1y;
			denom=d00*d11-d01*d01;
			v=(d11*d20-d01*d21)/denom;
			u=(d00*d21-d01*d20)/denom;
			w=1-u-v;
			if(0<=v&&v<=1&&0<=u&&u<=1&&0<=w&&w<=1)
				board[bh-1-i][j]='*';
		}
	//画边框
	for(inti=0;i<bw;i++)
	{
		board[0][i]='-';
		board[bh-1][i]='-';
	}
	for(inti=0;i<bh;i++)
	{
		board[i][0]='|';
		board[i][bw-1]='|';
	}
	board[0][0]=board[bh-1][0]=board[0][bw-1]=board[bh-1][bw-1]='+';
	printBoard();

	return0;
}
voidprintBoard()
{
	inti,j;
	for(j=0;j<bh;j++)
	{
		for(i=0;i<bw;i++)
			putc(board[j][i],stdout);
		putc('
',stdout);
	}
}

就是枚举三角形点来画的。
