/* ParallelSplitShadowMap written by Adrian Egli
/* ParallelSplitShadowMap written by Adrian Egli
*
* this version has still a bug in mutli-thread application (flickering problem)
* to avoid the flickering problem try osgShadow --pssm --SingleThreaded your_scene.ive
*
* The Parallel Split Shadow Map only supports directional light for simulating the shadow.
* It's one of the most robust algorithm for huge terrain sun light's shadow simulation, if
* you need to shadow a terrain, or another huge scene, you should use Parallel Split Shadow Map
* or at least test it against your scene. Have fun.
