EtiC Galaxy simulation Files

EtiC is based upon GLFW, OpenGL and  runs on PC with MS Windows Vista.

The main evolutions on EtiC V2_1 compared to EtiC V2 are:
- planets surface magnetic field added as criterion for habitability
- reworked life stage transitions : no probabilities involved for transitions, addition of Eukaryotic cell level
- model of reset on Ôyoung systemsÕ: early huge impacts, stellar flares depending on stellar class
- integration of MW exoplanets catalog: locations in graphs, exoplanet view
- planets view and graphs window running on different threads to allow parallel display (default for Mac-OSX, option for MS-Windows)
- reworked planet transition log (parameter, integration in planet view)
- improvements, additions in galaxy graphs for statistics 
- galaxy dust shown in planet artist view

Please read the .pdf for a complete description.

To run the program,
on MS Windows:
- unzip the ÔEtiC V2_1 WindowsÕ file in a dedicated directory, this includes EticV2.exe and other files:
 ÔParticle.vertexshaderÕ and ÔParticle.fragmentshaderÕ,
 Ôtext.vertexshaderÕ and Ôtext.fragmentshaderÕ,
 ÔSphere.vertexshaderÕ and ÔSphere.fragmentshaderÕ files must be in same directory as EticV2.exe,
 the .bmp (texture images) and  the .ttf/.otf (font) files must be in same directory as EticV2.exe,
 glfw3.dll , freetype6.dll, zlib1.dll, pthread.dll (provided) should be either in same directory or in Windows System directory
- run Etic.exe.
on Mac OS X :
- unzip the ÔEtiC V2_1 MacOSxÕ file in a dedicated directory: EtiC.app includes all necessary resource files;
- run EtiC 


EtiCV2_1 has been tested 
- on PC (Windows 7) with Intel integrated HD and NVIDIA GeForce 630M GPUs.
Performance will depend on the GPU HW: 
on PCs if you have an NVIDIA GPU and Laptop with Optimus technology,
   use the NVIDIA Control Panel to add manually EtiC.exe in the list of programs using the NVIDIA GPU.
Same should apply with AMD, ATI or other GPUs (not tested however - feedback is much welcome on this point).
Note: you can identify the GPU vendor, OpenGL and GLSL releases with the Info toggle command icon
- on Mac OS X with Intel Iris Pro Graphics 6200 

Source files, documentation, XCode and DevC++ project file are available in the ÔEtiC V2_1 sourceÕ zip file. 
These may be reused for any purpose, but without warranty. 

Please note:

1/ SW published by Ingo Berg (Simulating a Galaxy with the density wave theory, see
http://articles.beltoforion.de/article.php?a=spiral_galaxy_renderer&hl=en#idIntro)
and ACRETE algorithm implementation of STARGEN ) have been reused.

2/ Following libraries are required for linking on Windows:
-lglfw3dll -lglew -lopengl32 -lfreetype -lpthread

For GLFW the dll, library and include are those of GLFW 3.2
