at the same time, by subdividing an icosahedron and projecting all its vertices onto the unit sphere from the center, we can get a spherical triangle mesh with subdivision topology.
然后,将一个正多面体进行细分并将每一次细分所产生的新顶点投影到单位球面上,如此生成一个细分网格。
the monotone coefficients of the spaces and the upper(lower) monotone coefficients of a point of the unit sphere are computed.
并计算该空间的单调系数及该空间单位球面上任意一点的上(下)单调系数。
this method is based upon the projecting transformation between the points on the surface of a unit sphere which is centered at the viewer and the points on image planes.
该方法基于位于以视点为中心的单位球表面上的点与图像面上的点之间的投影变换。
based on the sphere earth model, two methods of gvd are proposed in this paper. one is assistant unit sphere method(ausm), and the other is ellipse model direct method(emdm).
moebius second fundamental form is important moebills invariable on the unit sphere of submanifolds, in this paper, we classify the surface in s~3 with semi—parallel moebius second fundamental form.
