Project Overview

• Abstract:
  
  GLOS is a graphic library intended to display and animate 3d objects in real-time onto a X-Window. Implementing a subset of the OpenGL library, it cares about observing OpenGL primitive naming and rendering methods. It is also entirely developed in ANSI Common Lisp, but features some specific CMU/CL optimizations enabling about 1/4 of MesaGL speed.



• Context:
  
  GLOS is an undergraduate research project followed by a team of five 4th-year students, supervised by two LaBRI teachers. It lasted 3 monthes, and took place in the Computer Science department of the University of Bordeaux I, France.



• Features:
  
  
  • Gouraud shading rendering.
  • Phong lighting.
  • Z-buffer (near and far clippings).
  • 8 directional colored lights.
  • Material (ambiant, diffuse, specular), but no texturing.
  • Vertex-Array implemented to speed-up faces processing.
  • External utility to process ASC objects.
  
  See the User Manual for an exhaustive listing.
  
  
• Compatibility:
  
  GLOS requires CMU/CL and CLX to run, so it is basically intended to Unix platforms.
  
  The Defsystem package is required for compilation.
  
  For optimization purposes, the code contains CMU/CL-specific compilation directives which makes it non full-ANSI Common Lisp, and then affects its portability to other ANSI Common Lisp systems. However, one can easily remove them (S-expressions with declaim, the, etc...) using sed utility, taking the risk to significantly decrease the overall efficiency of the recompiled code. Contact us for more details.



• License:
  
  GLOS is under GPL license.

2. Documentation:
   
   For now, all available manuals are in French (cf French section). Therefore, we suggest you to download the User Manual anyway in order to list the implemented OpenGL primitives.
   The comments in the code are in English.
