Polar coordinates of vertices of a hexagonal grid?
Is it possible to parameterize a hexagonal grid in polar plane?
In other words, is it possible to find polar coordinates of the centers of every hexagon packed in a hexagonal grid? The central hexagon is marked by a blue circle, and its polar coordinates is (0, 0)/
Solution
The centers are found every 60° and at distance twice inscribed radius. Compute the coordinates of the closest centers at 0° and 60° and every other center is obtained as a linear combination with integer coefficients.
2u + v, √3 v
Then convert to polar coordinates
r= 2√[u² + uv + v²]
tan Θ = √3 v / (2u + v)
