In order to communicate the research of spatial graphics and numbers, the coordinate system of spatial Cartesian coordinates must establish the relationship between spatial points and ordered arrays. Therefore, we can introduce spatial Cartesian coordinate systems. Zero point O is used as three vertical number axes. They all take o as the origin and generally have the same length unit. these three axes are collectively referred to as the X axis (horiz
