opcode是功能强大，跨平台的物理引擎，ogreopcode则是针对Ogre图像引擎封装的opcode物理库。-opcode is a powerful, cross-platform physics engine, ogreopcode is for Ogre graphics engine package opcode physical library.

Ogre OpCode:利用OPCODE库，在OGRE中做精确的碰撞检测（opcode即物理引擎ode使用的库）-Ogre OpCode: use OpCode library at Ogre in to do precise collision detection (opcode that ode physics engine used in the Treasury)
