| 函数名
|
| Function: list llGetBoundingBox( key object )
|
| 参数：key object –group, avatar or prim UUID that is in the same region
|
| 返回值：以局部坐标返回一个列表，该列表是对象相对于其根prim的边界框。
|
| 注意事项
|
注意事项
- 不管object是否是非根的prim，都会返回该对象的边界框。如果object是一个坐在对象上的代理，这也适用——返回坐在对象上的边框(包括代理的形状)。
- 附件没有自己的边界框(因为它们没有物理交互[1])，相反角色的边界框会被返回。

"\nBounding Box Size: " + (string)size, <1.0, 1.0, 1.0>, 1.0);
}
}
// Enclose a named object in the tightest possible box
// that is aligned with the object's root prim axes.
// Drop this script in a box near the object to enclose
// (must be in a 10m range)
