Detailed Description

The PxTaskManager interface.

A PxTaskManager instance holds references to user-provided dispatcher objects, when tasks are submitted the PxTaskManager routes them to the appropriate dispatcher and handles task profiling if enabled. Users should not implement the PxTaskManager interface, the SDK creates it's own concrete PxTaskManager object per-scene which users can configure by passing dispatcher objects into the PxSceneDesc.
