0003 ==================
0004
0005 This executable creates and persists simple demo geometries, using the tests/DemoGeo.h struct.
0006 Invoke the executable with::
0007
0008     cd ~/opticks/CSG
0009     ./CSGDemoTest.sh
0010
0011 To apply the above script to all the demo geometries use ``./make_demos.sh``
0012 Render the geometries with::
0013
0014     cd ~/opticks/CSGOptiX
0015     ./cxr_demo.sh
