Introduction to Graph Theory: Finding The Shortest Path (Part 2)

February 25, 2013 in Uncategorized by Adrian Marius

A couple of weeks ago I did an introduction to graph theory using Dijkstra’s algorithm. I received some awesome feedback so this week I want to take it a step further and build on that using the A* algorithm. The big difference between A* and Dijkstra’s algorithm is the addition of a heuristic function. This heuristic function allows us to give a best guess of which path to take rather than always taking the path that is the shortest distance from the source node. If you’re a gamer or someone looking to get into game development this algorithm is the basis of how path finding is done in a lot of games.

The StarCraft path-finding hack

February 21, 2013 in Tips & Tricks by Adrian Marius

Game-unit path-finding is something that most players never notice until it doesn’t work quite right, and then that minor issue becomes a rage-inducing, end-of-the-world problem. During the development of StarCraft there were times when path-finding just didn’t work at all.

February 20, 2013 in Tutorial by admin

Follow this link for a nice article about soft shadow mapping.

Shadow mapping is one of those things that a lot of people struggle with. It is also a very old shadowing technique that has been improved in a variety of ways. I’d like to make a brief trip trough the history of shadow mapping hopefully shedding some light on the topic and introduce you to some very nice techniques.

Linux kernel 3.8 available

February 19, 2013 in Linux, News by admin

“Unicycling Gorilla” is the code name for Linux 3.8, released today by Linus Torvalds after ten weeks of development. The name is once more derived from an event in Torvald’s life and an anecdote without significance, but many Linux users will benefit from the many enhancements in the latest kernel version.

In this kernel version, the Nouveau kernel driver will include everything that the OpenGL driver – which is part of current versions of Mesa 3D and is also called Nouveau – needs to use the 3D acceleration of all GeForce graphics chips available so far, without further configuration. F2FS (Flash-Friendly File System) support was also added. Additional features were added to both Btrfs and Ext4.

The Zend Optimizer+ is open source

February 19, 2013 in News, Source Code by admin

The Zend Optimizer+ provides faster PHP execution through opcode caching and optimization. It improves PHP performance by storing precompiled script bytecode in the shared memory. This eliminates the stages of reading code from the disk and compiling it on future access. In addition, it applies a few bytecode optimization patterns that make code execution faster.

This version of Zend Optimizer+ is compatible with PHP 5.2.*, 5.3.*, 5.4.* and PHP-5.5 development branch. PHP 5.2 support may be removed in the future.
