Two-dimensional and three-dimensional integrated weapon chess hexagonal grid generation method and device

Abstract

The embodiment of the invention provides a two-dimensional and three-dimensional integrated weapon chess hexagonal grid generation method and device. The method comprises the steps of selecting a drawing area from a target map, generating a first vertex set, and determining geometric center position coordinates of the drawing area; converting points in the first vertex set into points in a specified coordinate system to generate a second vertex set; calculating to obtain an equilateral hexagon according to the geometric center position coordinate and a preset side length, and generating a third vertex set; judging whether an intersection exists between the second vertex set and the third vertex set or not, and if so, storing the equilateral hexagon into an output set; and continuing to generate an equilateral hexagon towards the outer side of the geometric center based on the generated equilateral hexagon, and storing the equilateral hexagon with the intersection of the vertex and the second vertex set into the output set to generate the weapon chess hexagonal grid. In this way, the two-dimensional and three-dimensional integrated visualization effect of the hexagonal weapon chess lattices can be achieved, and the situation that the hexagonal weapon chess lattices are affected by distortion in a high-latitude area can be avoided.

Description

technical field [0001] The present application relates to the field of geographic image technology, and more specifically, to a method and device for generating a two-dimensional and three-dimensional integrated wargame hexagonal grid. Background technique [0002] Wargame is an important tool for logical deduction research and evaluation of the combat process, and an important method and means of modern combat simulation. The three major elements of wargames include the board, chess pieces and rules. The classic style of the chessboard is the hexagonal wargame board, and the hexagonal wargame board is often used in computer wargames to describe the terrain environment of the battlefield. [0003] Traditional wargame hexagonal grid generation algorithms are mostly implemented based on two-dimensional planes. However, with the development of the 3D geographic information display platform, war chess deduction has become a direction of its military application, and the traditi...

AI Technical Summary

Problems solved by technology

[0004] In order to realize the three-dimensional hexagonal grid wargame board drawing, some three-dimensional wargame hexagonal grid generation algorithms have been proposed, but these algorithms generally have some problems: they can only be displayed normally near the equator, and the closer to the high latitude area, the drawn hexagonal grid distortion The larger; it is only suitable for 3D scenes, and it is difficult to convert it into a 2D scene for perfect compatibility.
