@kitware/vtk-wasm

JavaScript bindings for loading and driving VTK compiled to WebAssembly — build 3D visualizations in the browser with no C++ required.

Full documentation, guides, and API reference: https://kitware.github.io/vtk-wasm/

Usage

Install the package:

npm install @kitware/vtk-wasm

Load the runtime, create a session, and use its vtk namespace:

import { loadAsync } from "@kitware/vtk-wasm";

const runtime = await loadAsync({ url: VTK_WASM_BUNDLE_URL });
const session = runtime.createStandaloneSession();
const vtk = session.vtk;

const cone = vtk.vtkConeSource();
// ... build and render your scene

No build step? Load the UMD bundle from a CDN and use the global vtkwasm:

<script src="https://unpkg.com/@kitware/vtk-wasm/vtk-umd.js"></script>

See the Loading VTK.wasm guide to get started and the API reference for every export.
