Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] In order to obtain a ray group beam with a better segmentation effect, the present invention expects to realize equal division of the ray beam through a non-regular polyhedron. Preferably, the present invention realizes the approximate generation of equally divided ray beams through C60 molecular polyhedrons. Since all faces of the non-regular polyhedron are not exactly the same, the generated ray beams are not completely equal, but it can meet the requirements of forward ray tracing.

[0023] C60 molecules such as image 3 As shown, there are 60 vertices, 90 edges and 32 faces, of which 12 are regular pentagons and 20 are regular hexagons, which is a highly symmetrical perfect molecular structure. In the present invention, by placing the source at the center of the C60 molecular polyhedron, and using the center and vertices of each face to form a pl...

Abstract

The invention relates to a method for generating equally-segmented ray beams for positive ray tracing. The method includes the steps that a source is placed in the center of an irregular polyhedron; the center of each face of the irregular polyhedron is connected with the vertex of the face; a triangle on each face is subjected to geometrical segmentation till a ray beam formed by the source and the vertex of each triangle meets the preset condition. According to the method, equally-segmented ray beams are approximately generated through the irregular polyhedron, positive ray tracing can be achieved faster, and angle errors between the equally-segmented ray beams can be reduced.

Description

technical field [0001] The invention relates to forward ray tracing, in particular to a method for generating separated ray beams such as forward ray tracing. Background technique [0002] Forward ray tracing is a widely used technology for predicting the propagation characteristics of radio waves. Its principle is to send a large number of ray beams uniformly from the source point to space, and then trace the path of each ray and use the receiving sphere to determine its impact on the receiving point. Does field strength contribute. [0003] In the process of forward ray tracing, generating equally spaced ray beams is a very critical key in the whole process. In the prior art, generally regular polyhedrons are used to generate equally spaced ray beams. In the prior art, there are only five kinds of regular polyhedrons, and the regular icosahedron has the largest number of faces, so the regular icosahedron is used to generate equally spaced ray beams. [0004] Icosahedron...
