Porting Arx Fatalis: Difference between revisions

Latest revision as of 08:25, 30 June 2018

This article tracks the status of the Arx Fatalis cross platform port. It also lists potential libraries to replace windows-specific code.

Linux / FreeBSD / Mac OS X Status

audio: done: abstracted audio backend, new OpenAL backend
io: done: abstracted with boost::filesystem and POSIX implementations
renderer: done: abstracted renderer backend, new OpenGL implementation, new D3D9 implementation
input: done: abstracted input backend, new SDL backend
windowing: done: backend abstracted, new SDL backend
misc: threads, timing code abstracted, msvc-specific string functions replaced, image code ported to DevIL, text rendering ported to FreeType
editor: todo (info)

Some features didn't make it...

-[http://www.libsdl.org/ SDL] has turned out to be the library of choice for the base init code, probably the input code and the setup for rendering. It can support both an OpenGL and a DirectX rendering context making it suitable for supporting the porting to OpenGL as well as the base D3D7 rendering code.

+[[Category:Development information]]
-While most of the functionalities were kept intact, porting some pieces of code was not making much sense.  A lot of texture operations were done in the original game that would now be performed using shaders.  Here's a list of what was removed and could someday be reintegrated into the game in another form.
-* Bump mapping: Was generated using the diffuse texture turned into grayscale.  The effect was performed using texture combine.  While using this technique could yield some interesting results, in most cases it produced a blurred effect.  Should be reimplemented as per pixel bump mapping using shaders.
-* PNUX texture effect: Color conversion applied to all textures in the game, resulting in funny looking scenes.  It seems like it was a cheat (activated as a spell), so in the end it was not worth porting.  Would be trivial to implement as a post processing effect.
-* HALO: Glowing effect around 2d items like runes & inventory items. Halo textures were built by scanning the original texture line by line and adding pixels when a boundary was found (when going from black to colored pixels).
-* Texture size option: To reduce the game textures quality... should be reintegrated.  The menu option & internal setting are still there, but have not effect.
-* 16 bit texture support: Reduce gfx & main memory usage, but with a cost in image quality. Pretty much useless now...
