| 摘要 |
The invention relates to a method for the discretization of a solid angle for use in a simulation or calculation process; wherein a solid angle extending about a center of a specified area, such as a radiation tile, is subdivided into a plurality of subdivisions, N, in such a manner that each subdivision corresponds to the same view factor, said subdivision being symmetric in relation to a normal vector of said specified area; wherein said subdivision starts from a circle at the north pole of a unit sphere, said unit sphere being subdivided into a series of radially consecutive rings, n; wherein each radially consecutive ring is then subdivided into a different number of ring segments in the azimuth direction; and wherein the number of subdivisions in each individual radially consecutive ring forms an arithmetical progression. |
