I have a weak spot for cool game development tools. Not the IDE, or art or sound tools – I mean the level editors, AI construction tools – those that developers develop specifically for their games. Those that you know could help you multiply your content, and craft your game […]

This tutorial covers basic algorithms with vectors.
Basic Vector Recipes
Geometry plays a central role in game programming, underlying not only graphics, but also physics and spatial AI. A lot has happened since geometry was first formalised by the Greeks more than two thousand years ago, most notably the invention of coordinates and vectors. These inventions are indispensible for doing […]
Vector Fundamentals
We have used tiles to decorate our living spaces for more than 4000 years. Tiles have several properties that make them attractive for use: they can be mass-produced; they are easy to build with (because of their geometric properties); and combinations of tiles lead to a huge number of decorative […]
Getting More out of Seamless Tiles
This article originally appeared in Dev.Mag Issue 21, released in March 2008. One way to populate large worlds with objects is to simply place objects on a grid, or randomly. While fast and easy to implement, both these methods result in unsatisfying worlds: either too regular or too messy. In […]
Poisson Disk Sampling
86 (Originally appeared in Dev.Mag Issue 20, released in February 2008.) Perlin noise is the foundation of many procedural texture and modelling algorithms. It can be used to create marble, wood, clouds, fire, and height maps for terrain. It is also very useful for tiling grids to simulate organic regions, and […]
