论文部分内容阅读
四维画法几何的旋转法是一个还没有被解决好的问题。本文第一部分内容是在施礼有《四维空间中几何元素的旋转原理及作图规律》论文的基础上,对与某一投影面成绝对垂直的平面为轴的旋转法进行了探讨。从而解决了能用空间变换法解决的问题,现在也能用旋转法解决。就我所知,到目前为止,关于四维画法几何旋转法,有关文献提出的方法仅有:与某一投影面成绝对垂直的平面为轴的旋转法;平行一投影空间的平面为轴的旋转法;平行一投影面的直线为轴的旋转法。本文提出另外一种旋转法即垂直一投影空间的直线为轴的旋转法,使四维画法几何旋转法的内容更加充实完善。这就是本文的第二部分内容。
Four-dimensional geometry method of rotation is a problem that has not yet been solved. The first part of this paper is based on the essay “Principle of Rotation and Geometry of Geometrical Elements in Four-Dimensional Space” by Xiali, and discusses the rotation method which takes an absolutely perpendicular plane as a projection plane. Thus solving the problem that can be solved by the space transformation method, and now it can also be solved by the rotation method. As far as I know, so far, concerning the method of geometric rotation of four-dimensional painting, the methods proposed in the literature are only: the rotation method of taking the plane perpendicular to a certain projection plane as the axis; the plane parallel to a projection space is the axis Rotating method; parallel to a projection plane of the axis of rotation method. In this paper, we propose another rotation method, that is, the rotation method of the straight line of a vertical projection space as the axis, so as to make the content of the four-dimensional geometric rotation method more substantial and complete. This is the second part of this article.
