我正在使用 .我正在将坐标存储在一个 2 - 或 3 - dimansicial 阵列中。
< pre{code> boost::: array< unt; 2/ * 3 */ & gt; coord;- I need a 方法来计算Z- order 中下一个框的坐标。 它会通过插入比分数, 增加一个比 解读增加一个, 但这样变得非常复杂 。 我希望在文章中执行类似于 cmp_zorder(...) 的拼写方式。
< div>OK 这里 s 这里有“ 平整” 添加算法, < code> < /code > 和 < code> 和 < code> < y < /code > 是输入和输出, 并且假定间断坐标中最低的顺序位是 x (与 < a href=> 中相同) http://en.wikipedia.org/wiki/Z- order_curve" rel= "nofol" > the wikipedia arts
int carry = 1;
do
{
int newcarry = x & carry;
x ^= carry;
carry = newcarry;
newcarry = (y & carry) << 1;
y ^= carry;
carry = newcarry;
} while (carry != 0);
我确实测试过 但只是一点点而已
