VTK 9.5 is out ​

June 24, 2025

The 9.5.0 release includes many improvments regarding the integration of WASM. In addition to observing VTK objects on the client side, you can also invoke methods on VTK objects. This enables us to implement client/server calls for handling picking with client side objects. The other hidden improvement is related to the increased number of vtk objects available in WASM which should help in reproducing more complex VTK scene more accurately.

You can install the equivalent python wheel with the command

sh
pip install "vtk==9.5.0" --extra-index-url https://wheels.vtk.org

The WASM bundle is available here:
