Some of the technical ideas are:

• World model and dynamics (positions, velocities, collisions of the world's objects) full platform independent
• Fast world-model dynamics and collision detection using simplified object models (not the full mesh)
• Careful 3D rendering with OpenGL to enable full compatibility with extern stereo vision systems
• Anaglyph mode implementation using color masking in OpenGL
• Multiplayer capabilities using UDP
• Good behaviors for CPU-controlled hovers, they could adapt to other player's behavior
• The platform-dependent code must be minimum and isolated to improve portability
• Careful and clear memory and pointers management to avoid any running problem
• Objects data file in a xml format containing xgl data
• Map files in xml format
