Visibility::VisibilityChecker Class Reference

#include <visibilitychecker.h>

---

Detailed Description

The VisibilityChecker manages all visibility systems. Its the interface for all access to the visibility system. If any entity is attached to a stage it will be registered by the checker and added to all attached visibility systems.

If the stage wants to check the visibility it just calls PerformVisibilityQuery which starts a new visibility check with the given observer entity and applies the result of the last frame check.
