why ogre

• used by many successful projects gallery showcase
  • used in several commercial applications (ankh,pacific storm,... , non-gaming applications...)
• big,helpful community irc://irc.freenode.net/Ogre3D forum wiki
  • has repeatedly taken part in google summer of code
• features superior to almost any other engine
  • mesh LOD, material LOD, various shadow techniques, shader-support for cg,hlsl and glsl
  • material scripting, particle scripting
  • hardware accelerated skeletal anim, anim blending, facial anim support
  • support for threaded background loading
• many powerful addons
• opensource, LGPL

IMHO ogre3d is currently the most powerful opensource 3d engine. it might not be that easy to learn as more limited engines, but its design is good and it is definitely a good choice in the long run. We've used it for both iris2 (3d ultima online client) and sfz (spacegame), but with lua instead of python, and are very happy with it. It is even used by several commercial application (possible with lgpl license), such as pacific storm and ankh, and some non-gaming applications as well. There is a book soley about ogre, and since recently also features in the popular "C++ How To Program" series of books (since 6th edition, see ogre hp)
