我正在尝试创建10.000六边形像蜜蜂梳子一样相互连接。我想创建所有这些作为一个元素,我可以将一些东西导入到它们内部。但是为了连接六边形,我的算法在连接前6后被卡住了元素。这是我在java中的算法。我在java中做了测试。 此外,我想让它们在连接之前变小。
angle= 2*Math.PI/6;
for (int i=0 ;i<6;i++){
double v = i*angle-(15);
pentagon pent = new pentagon(6, 60, a);
a.x=a.x+(int)Math.round(105*Math.cos(v));
a.y=a.y+(int)Math.round(105*Math.sin(v));
pentagonList.add(pent);
这是我的五角大楼

创建一个矩形网格是相当明显的 - 只是倾斜一个矩形网格(要么倾斜所有并得到一个平行四边形,然后使用模数来包装它,或者倾斜交替的行/列来创建一个矩形网格)。
创建一个装有六边形的六边形也很容易
所以如果你有x&amp;在两个数组polyX
和polyY
中你的六边形的坐标,你得到一个嵌套循环:
drawHex ( g, cx, cy, 0 );
for ( int rank = 1; rank < count; ++rank ) {
for ( int bar = 0; bar < 6; ++bar ) {
// x and y are twice midpoint of the previous face * the rank away
// from centre
int x = cx + ( polyX [ ( bar + 4 ) % 6 ] + polyX [ ( bar + 5 ) % 6 ] ) * rank;
int y = cy + ( polyY [ ( bar + 4 ) % 6 ] + polyY [ ( bar + 5 ) % 6 ] ) * rank;
// move by twice the distance of the midpoint of the next face each time
int dx = polyX [ bar ] + polyX [ ( bar + 1 ) % 6 ];
int dy = polyY [ bar ] + polyY [ ( bar + 1 ) % 6 ];
for ( int hex = 0; hex < rank; ++hex ) {
drawHex ( g, x, y, rank );
x += dx;
y += dy;
}
}
}
