- The Phanerozoic is the current and the latest of the four geologic eons in the Earth’s geologic time scale, covering the time period from 538.8 million years ago to the present. It is the eon during which abundant animal and plant life has proliferated, diversified and colonized various niches on the Earth’s surface, beginning with the Cambrian period when animals first developed hard shells that can be clearly preserved in the fossil record. The time before the Phanerozoic, collectively called the Precambrian, is now divided into the Hadean, Archaean and Proterozoic eons.
- Hexagonal Grids from Red Blob Games (redblobgames.com)
This guide will cover various ways to make hexagonal grids, the relationships between different approaches, and common formulas and algorithms. I’ve been collecting hex grid resources for over 25 years. I wrote this guide to the most elegant approaches that lead to the simplest code, starting from the guides by Charles Fu and Clark Verbrugge. Most parts of this page are interactive.
