bar3d

用 法：

void far bar3d(

int left, int top,// 三維空間矩形長條圖正面的左上角座標

int right, int bottom, //三維空間矩形長條圖正面的右下角座標

int depth, //三維空間矩形長條圖的深度（即陰影）

int topflag//設置是否繪製三維空間矩形長條圖的頂部

);

程序例:

#include <graphics.h>

#include

#include

#include

int main(void)

{

/* request auto detection */

int gdriver = DETECT, gmode, errorcode;

int midx, midy, i;

/* initialize graphics, local variables */

initgraph(&gdriver, &gmode, "");

/* read result of initialization */

errorcode = graphresult();

if (errorcode != grOk) /* an error occurred */

{

printf("Graphics error: %s\n", grapherrormsg(errorcode));

printf("Press any key to halt:");

getch();

exit(1); /* terminate with error code */

}

midx = getmaxx() / 2;

midy = getmaxy() / 2;

/* loop through the fill patterns */

for (i=EMPTY_FILL; i

{

/* set the fill style */

setfillstyle(i, getmaxcolor());

/* draw the 3-d bar */

bar3d(midx-50, midy-50, midx+50, midy+50, 10, 1);

getch();

}

/* clean up */

closegraph();

return 0;
