  • 第三点里我们规定左侧分枝取小于号，右侧分枝取大于号，与下文K-d树的构建6里插入左节点；否则插入右节点略有不同，也与p170的举例x<0.5，x>=0.5不符
  • 建议改为我们规定左侧分枝取小于号，右侧分枝取大于等于号，使上下文保持一致

  • 最后一段的标题为实现K-d树的建树和近邻查找，但内容似乎仅仅是关于近似最近邻的实现，建议把标题改为实现K-d树的近似最近邻查找

  • 5.3.3上面最后一句话，即使在平面点坐标偏离原点较大时也能很好地工作，文中没有提到原点被设定为初值，所以这句话的含义不明
  • 5.3.3第一段，我们仍然假设点集为X由n个三维点组成 -> 我们仍然假设点集为X，由n个三维点组成
