Octree is currently a popular representation of three-dimensional objects. Octree representation can effectively solve the problems of interference checking and hidden surface removal, but it needs large amount of memory and uses non-linear tree structure. Gargantini presents in [1] a linear octree encoding scheme for the above problems without dealing with the difference and display of objects. This paper, in FORTRAN programs, introduces the linear octree encoding scheme, explains in detail how to produce linear...

Octree is currently a popular representation of three-dimensional objects. Octree representation can effectively solve the problems of interference checking and hidden surface removal, but it needs large amount of memory and uses non-linear tree structure. Gargantini presents in [1] a linear octree encoding scheme for the above problems without dealing with the difference and display of objects. This paper, in FORTRAN programs, introduces the linear octree encoding scheme, explains in detail how to produce linear octree representation of volumes from their boundary representation and calculate differences between objects in linear octree representation. Finally, the display method of objects is introduced.

八叉树是当前较流行的一种三维物体表示方法,八叉树表示能有效地解决干涉检测及消隐的问题,但八叉树表示需占用大量空间而且采用非线性树状结构,因此Gargantini在[1]中提出了解决这两个问题的线性八叉树编码方法。Gargantini在[1]中没有涉及到物体的求差及显示的问题,因此本文结合FORTRAN程序介绍线性八叉树编码方法,详细说明如何从体系的边界表示产生体素的线性八叉树表示,如何对线性八叉树表示的物体进行求差运算。最后介绍物体的显示。

An effective algorithm is described that uses translation procedure instead of rotation to solve the arbitrary rotation of the octree of moving objects. The standard octree of a node at a high level is built up for the rotation, and the standard octrees at low levels can be deduced directly from that at the high level. After that, the rotation of all nodes at each level can be solved by means of translating the standard octree at that level. This method has the advantages of fast processing speed and less storage...
