  • General requirements:
Lib Min Version Note
CMake 3.12 Required
  • Osd optional requirements:
Lib Min Version Note
CUDA 4.0 cuda backend
TBB 2018 TBB backend
OpenCL 1.1 CL backend

Metal 1.2 Metal backend
  • Requirements for building optional examples:
Lib Min Version Note
GLFW 3.0.0 GL examples
Ptex 2.0 ptex viewers
Zlib (required for Ptex under windows)
  • Requirements for building documentation:

Build example to run glViewer and other example programs with minimal dependency

All platforms:

  • Install cmake and GLFW

make sure GLFW install directories are configured as follows:

   ${GLFW_LOCATION}/include/GLFW/glfw3.h
   ${GLFW_LOCATION}/lib/libglfw3.a (linux)
   ${GLFW_LOCATION}/lib/glfw3.lib (windows)
  • Clone OpenSubdiv repository, and create a build directory.
   git clone https://github.com/PixarAnimationStudios/OpenSubdiv
   mkdir build
   cd build

Windows (Visual Studio)

cmake ^
    -G "Visual Studio 15 2017 Win64" ^
    -D NO_PTEX=1 -D NO_DOC=1 ^
    -D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 ^
    -D "GLFW_LOCATION=*YOUR GLFW INSTALL LOCATION*" ^
    ..

cmake --build . --config Release --target install

Linux

cmake -D NO_PTEX=1 -D NO_DOC=1 \
      -D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 \
      -D GLFW_LOCATION="*YOUR GLFW INSTALL LOCATION*" \
      ..

cmake --build . --config Release --target install

macOS

cmake -G Xcode -D NO_PTEX=1 -D NO_DOC=1 \
      -D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 \
      -D GLFW_LOCATION="*YOUR GLFW INSTALL LOCATION*" \
      ..

cmake --build . --config Release --target install

iOS

SDKROOT=$(xcrun --sdk iphoneos --show-sdk-path) cmake -D NO_PTEX=1 -D NO_DOC=1 \
      -D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 \
      -D CMAKE_TOOLCHAIN_FILE=../cmake/iOSToolchain.cmake -G Xcode \
      ..
  • This will produce an “OpenSubdiv.xcodeproj” that can be open and the targets ‘mtlViewer’ and ‘mtlPtexViewer’ (if NO_PTEX is ommitted and libPtex.a is installed in the iOS SDK) that can be run
