- BVH objects are reference counted.
- The \f[C]rtcRetainBVH\f[] function increments the reference count of the
- passed BVH object (\f[C]bvh\f[] argument).
- This function together with \f[C]rtcReleaseBVH\f[] allows to use the
- internal reference counting in a C++ wrapper class to handle the
- ownership of the object.
- .SS EXIT STATUS
- .PP
- On failure an error code is set that can be queried using
- \f[C]rtcGetDeviceError\f[].
