该程序在显示三角形时的顺序是从顶点到底边,首先得定位顶点像素的坐行列坐标(dx,cx)则接其后的像素起始坐标为(dx+1,cx-1),终点坐标为(dx+1,cx+1),再接着的下一行像素的起始坐标为(dx+2,cx-2),终点坐标为(dx+2,cx+2),再下一行始终点坐标分别为(dx+3,cx-3),(dx+3,cx+3).依此类推直到最后一行的始终坐标分别为(dx+n,cx-n),(dx+n,cx+n).在写同行像素时用cmp cx,cx+n jnz Y 来实现循环,所以在这个循环过程中注意保护cx。-The program is displayed at the time of the order of triangle vertices in the end from the side, first of all have to sit pixel vertex positioning coordinates of the ranks of (dx, cx) is then the subsequent pixel coordinates for the start (dx+ 1, cx-1), end point coordinates for (dx+ 1, cx+ 1), followed by the next line starting pixel coordinates (dx+ 2, cx-2), end point coordinates (dx+ 2, cx+ 2), and then the next line always points coordinates, respectively (dx+ 3, cx-3), (dx+ 3, cx+ 3). and so on until the last line is always the coordinates were (dx+ n, cx-n), (dx+ n, cx2B ! n). At the time of writing pixels to use peer-cmp cx, cx+ n jnz Y to achieve the cycle, so in this cycle of the process of attention to the protection of cx.
