  Node Culling Multi-Hit BVH Traversal - Reference Implementation
-------------------------------------------------------------------

This package contains full source code for the reference
implementation of traversal callbacks and node culling multi-hit BVH
traversal featured in:

  C. Gribble.  Node Culling Multi-Hit BVH Traversal.  In Eurographics
    Symposium on Rendering (EI&I track), 2016.

Unless otherwise stated directly in the source, this code is
distributed under the BSD 3-Clause License (see LICENSE for more
information).


----------------------------------------------


Building the reference implementation requires CMake v3.0 (or higher).
CMake is available at:

  http://www.cmake.org/

Please ensure CMake v3.0 (or higher) is installed on your system
before proceeding.

Relevant CMake configuration options:

  - CMAKE_BUILD_TYPE : sets type of build (Release by default)

  - mhBVH_ENABLE_TCB_SUPPORT : Enables/disables TCB support in BVH
      traversal (ON by default)

  - mhBVH_ENABLE_WRITE_HITDATA_TEXT : Enables/disables writing of hit
      data as ASCII text (OFF by default)


----------------------------------------------


To build and run the 'mhBVH' driver program using the default build
configuration:


  Step 1.)  Run CMake on the source directory

    prompt> cd mhBVH
    prompt> mkdir build
    prompt> cd build
    prompt> cmake ..


  Step 2.)  Run make to build the 'mhBVH' executable

    prompt> make


  Step 3.)  Run the 'mhBVH' executable

    prompt> bin/mhBVH scenes/cbox.luxjr


Command line options for 'mhBVH' are listed when the driver program is
exectued without command line arguments.
