Rationale
This project is a personal goal. It is not done to gain work, or for an reason other than personal satisfaction.
Engine Choice
Freedom Nation uses the id Tech 4 game engine. This engine is open source, used for AAA games, has lots of documentation and supports most modern graphics features.
It also evolved from the earlier id Tech 1 to 3 engines which supported Quake to Quake 3.
I have chosen to use a modified version of the ioDoom3 engine called dhewm3. This version adds the following to the original id tech 4 engine:
- 64bit port
- SDL for low level OS support, OpenGL and input handling
- OpenAL for audio output, all OS specific audio backends are gone
- OpenAL EFX for EAX reverb effects (read: EAX on all platforms)
- A portable build system based on CMake
I then forked this project and keep my changes in separate github repository.
A really good review of the deep and detailed workings of the if tech 4 engine can be found at Fabien Sanglard's website.
