OpenSubdiv Lite Regressions

Overview

Regression tests for osd_lite

Requirements

• Windows or Linux
• CMake 3.22
• C++ 20

Build

1. Git clone this source tree

   git clone https://github.com/NVIDIA-RTX/OSD-Lite-Tutorials

2. Ensure you have a recent C++ std20 compiler such as the latest Visual Studio 2022 (run the Visual Studio updater application if unsure), Clang or GCC

3. Create a 'build' folder (at the top of the repository, names such as 'build' or '_build' are recommended)

4. Use CMake to configure the build.

   • CMake GUI : make sure you set the build folder ! ("Where to build the binaries" line)

   • You can also use the command line or scripts:

     cmake_cmd="C:/Program\ Files/CMake/bin/cmake.exe"
     cmd="$cmake_cmd
          -G 'Visual Studio 17 2022 -A x64'
          .."
     echo $cmd
     eval $cmd

5. Build : either open the solution in MSVC or use the CMake command line builder

   cmake --build . --config Release

Warning

32 bits builds are not supported

Running Tests

From the build directory, use the ctest command. Ex:

ctest -C Release

Alternatively: use the build_and_run.sh bash script (edit as necessary). It should work out-of-the-box for git-bash on windows, as well as linux bash (including WSL).
