Embodiment Construction
[0028] Such as Figure 4 As shown, the present invention includes three stages: the first stage is to create the template tile; the second stage is to determine the tile resolution; the third stage is to display the tile.
[0029] The steps in the first phase are as follows:
[0030] 1) Create a hexagonal grid in which the number of hexagonal units (hexagonal grid resolution) in the X and Y axis directions is k (k is an integer multiple of 2) as a template block. Each unit in this template block is a regular hexagon with side length 1. The coordinates of the lower left vertex of the minimum axial bounding box of the template block are (0,0). The six vertex coordinates of each cell are calculated in turn. The calculation order can be set to process each unit from left to right and bottom to top. Inside each unit, all 6 vertices are calculated in counterclockwise order starting from the lower left vertex.
[0031] If the vertex coordinates of the template block are stored i...
