HVVR
Hierarchical visibility for VR and real time rendering of effects
...It implements a hybrid CPU/GPU raycaster, suited for real-time rendering of effects such as lens distortion. By default, raycaster.vcxproj is configured to build all .cu files to the compute_61,sm_61 target. If your GPU needs a different code-gen target, you can change this in the raycaster project properties. Some installations of the CUDA SDK and Visual Studio integration appear to have broken build dependency tracking. If you're seeing behavior after code modification that looks like stale code from header files referenced in .cu files, try cleaning the solution and building from scratch (or install a newer CUDA Toolkit).
