    8181The project is separated into one section containing supportive code (utils), the traversal algorithms (traversal), and the basic engine classes like Camera, Geometry, Material, or RenderState (rendering).  
    8282 
    83 the tool uses some free 3rd party libraries, like DevIL for the image processing, and glfont2 for the HUD (http://students.cs.byu.edu/~bfish/glfont2.php, many thanks to Brad Fish for fast antialiased text). Also thanks to Alexander Kusternig for providing me his code for the SSAO shader. 
     83The tool employs some free 3rd party libraries:  
     84 
     85DevIL for texture loading / unloading 
     86glfont2 (http://students.cs.byu.edu/~bfish/glfont2.php) for the antialiased fonts of the HUD. Thanks to the author Brad Fish.  
     87The RenderTexture library. Thanks to the author Mark J. Harris.
