Hexagonal Grid Spiral Coordinates Guide Updated

2025-03-15

The author updated their popular hexagonal grid guide with a new section on spiral coordinate systems. Despite not yet using them in a real project, they decided to stop waiting and share their current understanding, including unoptimized sample code. More variants will be added in the future. Additionally, they discovered a simplified angle sorting method using axial coordinates, which is detailed on a separate page.

Planetary Orbit Spirographs Based on Kepler's Laws

2025-01-23

Inspired by John Carlos Baez's post on the Pentagram of Venus, Red Blob Games created a set of planetary orbit spirographs. Using Kepler's Third Law to convert orbital periods to distances from the sun, the site generates heliocentric planetary orbit images resembling spirographs. Data includes Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, and Neptune.
