Module point_gen

This module covers generating points in a hexagonal fashion.

Structs

HexTerrainMesh

Represents terrain, however it contains the vertices only once.

HexWaterMesh

Water mesh which contains vertex data for the water mesh.

TerrainVertex

Represents the center of a single hexagon.

Constants

A 🔒

X multiplication factor. 1.0 / sqrt(2)

B 🔒

Y multiplication factor. sqrt(3) / sqrt(2) == sqrt(1.5)

C45 🔒

cos(45deg) is used to rotate the points.

S45 🔒

sin(45deg) is used to rotate the points.
