Include Statements

• Use double quotes (“”) to include header files that live in the same directory as your source code.

• Use angle brackets (<>) to include header files from outside a file’s directory.

• Public headers for a library must be placed in the library’s source directory, not in a subdirectory.

• Do not use absolute paths in #include directives. Any explicit path in front of the filename should be relative to the top of the relevant package. (See examples below.)

• Order includes as shown below. Within each subsection, list files in alphabetical order:

  // Include body's corresponding header first
  #include "PathIntegrator.h"
  // Include headers local to current library next
  #include "BsdfSampler.h"
  #include "LightSetSampler.h"
  // Include headers from internal libraries next
  #include <moonray/rendering/mcrt_common/Ray.h>
  #include <scene_rdl2/common/math/Constants.h>
  // Include headers from external libraries next
  #include <OpenImageIO/version.h>
  // Include C++ and system headers last
  #include <limits> 
  #include <memory>
