TestZeroCopyPython

This is an example showing how to use zero-copy datatransfer from a Python ndarray to vtkDataArray::SetArray w/callback.

Building

This project requires VTK, Python, Numpy, and SWIG.

Note: VTK needs to first be patched!

cd /path/to/VTK
git fetch http://review.source.kitware.com/p/VTK refs/changes/72/14072
git checkout FETCH_HEAD -b array-mem-management
cd /path/to/vtk-build
make

Once VTK is patched the example can be built:

mkdir /path/to/example-build
cd /path/to/example-build
cmake -DVTK_DIR=/path/to/vtk-build /path/to/example-source
make

Running

The example can be run form its build directory:

PYTHONPATH=/path/to/example-build python /path/to/example-source/TestZeroCopyPython.py
