一个粗陋的三角形填充算法

 谢谢我的老师，唐泽圣教授在其《计算机图形学基础》一书中导出的通用bresenham画线算法代码

     /**/ /**
     *sample to fill a trangle on 2d screen
     */
     public   void  fillTriangle( int  x1, int  y1, int  x2,  int  y2, int  x3, int  y3) ... {
        System.out.println("fillTriangle:");
        System.out.print(x1+","+y1+",");
        System.out.print(x2+","+y2+",");
        System.out.println(x3+","+y3+",");
        
        int ymin,ymax;
        
        ymax=Math.max(Math.max(y1,y2),y3);
        ymin=Math.min(y1,Math.min(y2,y3));
        System.out.println("maxY="+ymax+" minY="+ymax);
        triangleScanlineMinMaxArrays=new int[(ymax-ymin+1)][];
        triangleDeltaY=ymin;
        
        calculateLine(x1,y1,x2,y2);
