JavaScript => public function QueryIndices(visible: bool, result: int[], firstIndex: int): int;
JavaScript => public function QueryIndices(distanceIndex: int, result: int[], firstIndex: int): int;
JavaScript => public function QueryIndices(visible: bool, distanceIndex: int, result: int[], firstIndex: int): int;
C# =>public int QueryIndices(bool visible, int[] result, int firstIndex);
C# =>public int QueryIndices(int distanceIndex, int[] result, int firstIndex);
C# => public int QueryIndices(bool visible, int distanceIndex, int[] result, int firstIndex);

Parameters 参数

visible	True if only visible spheres should be retrieved; false if only invisible spheres should be retrieved. true则检索可见边界球，false则检索不可见边界球。
distanceIndex	The distance band that retrieved spheres must be in. 边界球的距离必须在检索范围。
result	An array that will be filled with the retrieved sphere indices. 边界球索引的数组。
firstIndex	The index of the sphere to begin searching at. 首次查找的边界球索引。

Returns 返回

int The number of sphere indices found and written into the result array.

Description 描述

Retrieve the indices of spheres that have particular visibility and/or distance states.

检索拥有特别的可见的或者距离状态的球形索引。

Use the overload that corresponds to the state properties you are interested in. For example, if you want to retrieve visible spheres in any distance band, use the overload that takes a 'visible' parameter but does not have a 'distanceIndex' parameter.

使用overload与你感兴趣的状态属性相一致。例如：如果你想重新使球形在任何距离带可见，使用overload取'visible'参数但是没有'distanceIndex'参数。

The length of the result array is used to limit the number of spheres checked. If you provide a result array of length 20, and a firstIndex of 10, then the query will only examine spheres 10 through 30 to see if they meet the given visibility and/or distance constraints.

结果数组的长度被用来限制检查球形的数量。如果你提供长度为20的数组并且首索引为10，然后查询只会检查球10到30,看看是否满足给定的可见性和/或距离约束。
