fragment在OpengGL中翻译成“片断”。那么Ogre中的下面这段话呢:
The RaySceneQueryResult returns an iterator of RaySceneQueryResultEntry structs. This struct contains three variables. The distance variable tells you how far away the object is along the ray. One of the other two variables will be non-null. The movable variable will contain a MovableObject if the Ray intersected one. The worldFragment will contain a WorldFragment object if it hit a world fragment (like the terrain).
最后一句话我怎么翻译才更恰当呢?
