0002 SGLFW_SOPTIX_Scene_test.cc
0003 ============================
0004
0005 Started from SOPTIX_Scene_test.cc, a pure CUDA ppm render of optix triangles,
0006 added OpenGL interop viz for interactive view and parameter changing.
0007
0008 Usage and impl::
0009
0010     ~/o/sysrap/tests/SGLFW_SOPTIX_Scene_test.sh
0011     ~/o/sysrap/tests/SGLFW_SOPTIX_Scene_test.cc
0012
0013 As this and alias are now installed can just use::
0014
0015     SGLFW_SOPTIX_Scene_test.sh
0016     ssst.sh
0017
0018 For a simpler non-encapsulated non-interactive OptiX only ppm render test, see::
0019
0020     ~/o/sysrap/tests/SOPTIX_Scene_test.sh
0021     ~/o/sysrap/tests/SOPTIX_Scene_test.cc
0022
0023 DONE: view maths for raytrace and rasterized now match each other quite closely
