[[ MultiBrain ]]

MultiBrain is a 3D graphic engine based on OpenGL and entirely written in C++, it provides an articulated hierarchy of 3D objects and primitives using a portal-based structure.
It is able to load 3D maps, polygonal meshes, obj models, NURBS and trimmed NURBS surfaces, Bitmap textures and TGA textures. At this time MultiBrain implements a certain number of 3D features like texturing, alpha-blending, shadows, reflections and some complex rendering technics besides a little physical engine. The entire project was created to be an environment simulator rather then a gaming framework. The features already implemented are:

• map loading (.mb)
• polygonal mesh loading (.m)
• models loading (.obj)
• NURBS and trimmed NURBS loading (.db)
• OpenGL shading and lighting
• texture mapping and autotexturing
• environment mapping (sphere mapping, cube mapping)
• Phong hightlights over texture
• bitmap and TGA (RLE o raw) texture formats
• alpha blending
• static and realtime lightmaps
• static and realtime reflections
• realtime shadows with shadow-volumes
• dynamic clipping with occlusion-query
• text printing with 2D bitmapped fonts
• Cg e GLSL shaders loading
• collision detection with cylindrical and spherical bounding boxes
• the physical engine which can simulate:
  • accelerations
  • gravity
  • friction
  • collisions

This software must be considered an experimental project, it has a lot of testing features, some unstable code and probably a certain number of bugs, so it must be handle with care :).
