Chapter 213: VTKLoader

Core Idea

A loader for the VTK format.

This loader only supports the POLYDATA dataset format so far. Other formats (structured points, structured grid, rectilinear grid, unstructured grid, appended) are not supported.

Code Examples

const loader = new VTKLoader();
const geometry = await loader.loadAsync( 'models/vtk/liver.vtk' );
geometry.computeVertexNormals();
const mesh = new THREE.Mesh( geometry, new THREE.MeshLambertMaterial() );
scene.add( mesh );

What it demonstrates: Typical usage of VTKLoader.
