Presentation
The PyCon JP 2026 talk introduces pyvista-wasm with live demos and a deep dive into the WASM rendering architecture:
Differences from pyvista-js
This project replaces the vtk.js rendering backend used in pyvista-js with VTK.wasm (@kitware/vtk-wasm npm package).
Key differences:
- Rendering backend: VTK.wasm (WebAssembly port of VTK C++) instead of vtk.js (pure JavaScript reimplementation)
- API style: VTK.wasm uses
vtk.vtkRenderer()factory functions on a namespace object, vs vtk.js'svtk.Rendering.Core.vtkRenderer.newInstance()hierarchy - Initialization: VTK.wasm requires async initialization via
vtkWASM.createNamespace()to load the WASM binary - Feature parity: VTK.wasm provides access to the full VTK C++ API, enabling features not available in vtk.js
