我正在嘗試創建一個基於體素的遊戲，並且渲染了數百萬個立方體。分組網格上的食人魔碰撞檢測？
爲了加快渲染速度，我將多維數據集分組爲多個塊，將32x32x32多維數據集分組爲一個網格。這是爲了減少對GPU的渲染調用次數並提高幀速率。
我正在使用ManualObject來建立塊，它的工作原理完美。但是，現在的問題是，由於各個塊不是與個別場景節點相關的實體，所以我找不到一種方法來執行碰撞檢測。
食人魔是否有辦法單獨使用ManualObject的子網？

Ogre3D是一個渲染引擎;它不會進行碰撞檢測。 –
食人魔有他們自己的論壇，我親自使用，他們非常好。我會對你的問題表示贊成 –
哦，對，我也會在Ogre論壇上發表。 @NicolBolas，的確如此。我只是根據他們在他們的維基上的一些Ogre教程來制定個別實體的碰撞檢測。我認爲，因爲他們可以爲實體做這件事，那麼也許他們會爲我正在做的事情做出類似的事情。 –
