Hyperbolic tilings | Isogonal tilings | Semiregular tilings | Truncated tilings
In geometry, the truncated tetraoctagonal tiling is a semiregular tiling of the hyperbolic plane. There are one square, one octagon, and one hexakaidecagon on each vertex. It has Schläfli symbol of tr{8,4}. (Wikipedia).

How to construct a Tetrahedron
How the greeks constructed the first platonic solid: the regular tetrahedron. Source: Euclids Elements Book 13, Proposition 13. In geometry, a tetrahedron also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. Th

The geometry of the regular tetrahedron | Universal Hyperbolic Geometry 45 | NJ Wildberger
We look at the geometry of the regular tetrahedron, from the point of view of rational trigonometry. In particular we re-evaluate an important angle for chemists formed by the bonds in a methane molecule, and obtain an interesting rational spread instead. Video Content: 00:00 Introduction

Code-It-Yourself! Simple Tile Based Platform Game #1
This video shows how to make a simple yet smooth tile-based 2D platform game, similar to classic offerings from older consoles. It uses nothing but the Windows Command Prompt to demonstrate robust collisions between the scenery and the player. All collisions are resolved using floating poi

Super Fast Ray Casting in Tiled Worlds using DDA
In this video I look at how the "traditional OLC" method of raycasting in various videos is in fact terrible, and look at the more intelligent DDA algorithm which can significantly (orders of magnitude) be more effective at determining ray length in tile or voxel based worlds. Source: htt

If the celebrated Scottish zoologist D’Arcy W. Thompson (1860 – 1948) could have met the near-legendary German astronomer Johannes Kepler (1571 – 1630), what would they talk about? Snowflakes, maybe? It is true that both men wrote about their hexagonal shapes. But they both wrote about Arc
