README
OpenSubdiv
OpenSubdiv is a set of open source libraries that implement high performance subdivision surface (subdiv) evaluation on massively parallel CPU and GPU architectures. This codepath is optimized for drawing deforming subdivs with static topology at interactive framerates. The resulting limit surface matches Pixar's Renderman to numerical precision.
OpenSubdiv is covered by the Apache license, and is free to use for commercial or non-commercial use. This is the same code that Pixar uses internally for animated film production. Our intent is to encourage high performance accurate subdiv drawing by giving away the "good stuff".
Feel free to use it and let us know what you think.
For more details about OpenSubdiv, see Pixar Graphics Technologies.

Build example to run glViewer and other example programs with minimal dependency
All platforms:
- Install cmake, GLFW and GLEW (GLEW is not required on OSX)
make sure GLEW and GLFW install directories configured as follows:
${GLEW_LOCATION}/include/GL/glew.h
${GLEW_LOCATION}/lib/libGLEW.a (linux)
${GLEW_LOCATION}/lib/glew32.lib (windows)
${GLFW_LOCATION}/include/GLFW/glfw3.h
${GLFW_LOCATION}/lib/libglfw3.a (linux)
${GLFW_LOCATION}/lib/glfw3.lib (windows)
- Clone OpenSubdiv repository, and create a build directory.
git clone https://github.com/PixarAnimationStudios/OpenSubdiv mkdir build cd build
Windows (Visual Studio)
- run cmake:
"c:/Program Files (x86)/CMake/bin/cmake.exe" ^ -G "Visual Studio 12 Win64" ^ -D NO_PTEX=1 -D NO_DOC=1 ^ -D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 ^ -D "GLEW_LOCATION=*YOUR GLEW INSTALL LOCATION*" ^ -D "GLFW_LOCATION=*YOUR GLFW INSTALL LOCATION*" ^ .. - Open OpenSubdiv.sln in VisualStudio and build.
Linux
cmake -D NO_PTEX=1 -D NO_DOC=1 \
-D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 \
-D GLEW_LOCATION="*YOUR GLEW INSTALL LOCATION*" \
-D GLFW_LOCATION="*YOUR GLFW INSTALL LOCATION*" \
..
make
macOS
cmake -G Xcode -D NO_PTEX=1 -D NO_DOC=1 \
-D NO_OMP=1 -D NO_TBB=1 -D NO_CUDA=1 -D NO_OPENCL=1 -D NO_CLEW=1 \
-D GLFW_LOCATION="*YOUR GLFW INSTALL LOCATION*" \
..
make
iOS
- Because OpenSubdiv uses a self-built build tool (stringify) as part of the build process, you'll want to build for macOS and build the stringify target
SDKROOT=$(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 STRINGIFY_LOCATION="*YOUR MACOS BUILD LOCATION*"/bin/stringify \
-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
