0003 PIP : OptiX 7 Ray Trace Program Pipeline
0004 ==========================================
0005
0006 Aiming to keep this geometry independent, so it is just
0007 responsible to convert the ptx code into an optix
0008 ray trace pipeline.
0009
0010 The pip(PIP) instance is instanciated in CSGOptiX::initPIP
0011 and passed as ctor argument to SBT
