External version of the ospModelViewer from the ospray source tree with added scripting and benchmark capabilities.

This project requires a valid install of OSPRay, which can be found at https://github.com/ospray/OSPRay. There are instructions there for how to build OSPRay from source. Alternatively, binary releases posted with each OSPRay release will also work.

Currently ospDebugViewer is only supported on Linux and OS X using either gcc or clang. In principle, ospDebugViewer should work on Windows, but it is not officially tested or supported at this time. Additionally, the scripting library used does not support compiling with icc at the moment. However, OSPRay itself can be compiled with icc and used in ospDebugViewer.

One you have a valid OSPRay installed, building ospDebugViewer is fairly straightforward. First, you will have to have GLUT installed, which can be installed on Debian based Linux distros by installing the 'freeglut3-dev' package, or yum based RHEL flavors with the 'freeglut-devel' package. On OS X, GLUT can be found via Macports or Homebrew.

Once OSPRay and GLUT are installed, you're ready to compile ospDebugViewer. CMake looks for your OSPRay install via the 'ospray_DIR' environment variable, which should point to the root of your OSPRay install. Thus on a machine where OSPRay is installed into '/opt/ospray', compiling ospDebugViewer is a simple as:

user@mymachine[~/Projects/ospDebugViewer]: mkdir build
user@mymachine[~/Projects/ospDebugViewer/build]: cd build
user@mymachine[~/Projects/ospDebugViewer/build]: export ospray_DIR=/opt/ospray
user@mymachine[~/Projects/ospDebugViewer/build]: cmake ..
user@mymachine[~/Projects/ospDebugViewer/build]: make

The 'scripts/' directory in the ospDebugViewer source tree has some scripts which know how to go fetch OSPRay, compile it with gcc, and build ospDebugViewer with it. You can run the 'scripts/build_linux.sh' script to do this, where it will create an 'ospray' directory containing ospray source, build, and install, and a 'build' directory where ospDebugViewer is compiled.
