C# Class Axiom.SceneManagers.Bsp.BspLevel

Holds all the data associated with a Binary Space Parition (BSP) based indoor level.

The data used here is populated by loading level files via the BspLevelManager.Load method, although application users are more likely to call SceneManager.SetWorldGeometry which will automatically arrange the loading of the level. Note that this assumes that you have asked for an indoor-specialized SceneManager (specify SceneType.Indoor when calling Engine.GetSceneManager).

We currently only support loading from Quake3 Arena level files, although any source that can be converted into this classes structure could also be used. The Quake3 level load process is in a different class called Quake3Level to keep the specifics separate.
