1)  sequential coded Quardtree
顺序四叉树
1.
In order to fast culling invisible data and make result of progressive rendering reasonable, a sequential coded Quardtree is built with points clouds evenly distributed to nodes of every layer from top to down.
该方法通过构建一棵顺序四叉树使点云均匀分布在四叉树节点上,来实现快速的数据筛选。

3)  Ordered Quad-tree
有序四叉树
1.
An Image Encoding Algorithm of Ordered Quad-tree in High Frequency Subbands;
一种基于高频子带的有序四叉树图像编码算法
2.
Namely the lowest frequency subband is encoded separately,the ordered quad-tree is defined in high frequency subbands so that the important wavelet coefficients are transmitted by priority,and the run-length is applied.

【四教──龙树四教】
  ﹝出华严经随疏演义钞﹞
  龙树论师乃西天第十三祖。尝立四教判释经论,故云龙树四教也。
  [一、有门],谓阿含小乘等经,说一切因果之法,悉皆实有,是为有门。(梵语阿含,华言无比法。)
  [二、空门],谓大品般若等经,说真空实相之理,荡除众生情执,是为空门。(梵语般若,华言智慧。)
  [三、亦有亦空门],谓深密等诸大乘经,说有谈空,互相无碍,是为亦有亦空门。
  [四、非有非空门],谓中论等说一切法皆即空之有,是非有;即有之空,是非空;互泯互融,即第一义,是为非有非空门。
