If OPTIX_BUILD_OPERATION_UPDATE the output buffer is assumed to contain the result of a full build with OPTIX_BUILD_FLAG_ALLOW_UPDATE set and using the same number of primitives. It is updated incrementally to reflect the current position of the primitives. If a BLAS has been built with OPTIX_BUILD_FLAG_ALLOW_OPACITY_MICROMAP_UPDATE, new opacity micromap arrays and opacity micromap indices may be provided to the refit.
