// # class PolygonTreeNode
// This class manages hierarchical splits of polygons
// At the top is a root node which doesn hold a polygon, only child PolygonTreeNodes
// Below that are zero or more 'top' nodes; each holds a polygon. The polygons can be in different planes
// splitByPlane() splits a node by a plane. If the plane intersects the polygon, two new child nodes
// are created holding the splitted polygon.
// getPolygons() retrieves the polygon from the tree. If for PolygonTreeNode the polygon is split but
// the two split parts (child nodes) are still intact, then the unsplit polygon is returned.
// This ensures that we can safely split a polygon into many fragments. If the fragments are untouched,
//  getPolygons() will return the original unsplit polygon instead of the fragments.
// remove() removes a polygon from the tree. Once a polygon is removed, the parent polygons are invalidated
// since they are no longer intact.
// constructor creates the root node:
//此类管理多边形的层次分割
//顶部是一个根节点，它不包含多边形，只有子PolygonTreeNodes
//下面是零个或多个“顶部”节点; 每个都有一个多边形。 多边形可以位于不同的平面中
// splitByPlane（）按平面拆分节点。 如果平面与多边形相交，则会有两个新的子节点
//创建持有分割多边形。
// getPolygons（）从树中检索多边形。 如果对于PolygonTreeNode，则多边形被拆分但是
//两个分割部分（子节点）仍然完好无损，然后返回未分割的多边形。
//这确保我们可以安全地将多边形拆分为多个片段。 如果碎片未受影响，
// getPolygons（）将返回原始的未分割多边形而不是片段。
// remove（）从树中删除多边形。 删除多边形后，父多边形将失效
//因为它们不再完好无损

// with width 2.0001 and height 0.999. If no object is found, the user supplied callback is
// called, which should generate a new object. The new object is inserted into the database
// so it can be found by future lookupOrCreate() calls.
// Constructor:
//   numdimensions: the number of parameters for each object
//     for example for a 2D rectangle this would be 2
//   tolerance: The maximum difference for each parameter allowed to be considered a match
