vtk

NOTE: You are probably looking for vtk.js instead!

This is something different providing node.js bindings to the binary c++ library.

node-vtk

VTK bindings for Node.js

This is a wrapper around VTK providing bindings to Node.js.

This module does not bring VTK itself but wraps around the version installed on your system.

Installation

If all goes well simply this should do it:

npm install vtk

It will build the wrapper classes matching the VTK installed on your system. Currently 8.1.1 is supported.

Building the wrappers might take a little while.

You might need to install following packages for example on Debian:

sudo apt-get install vtk8-dev qtbase5-dev

Usage

For example drawing a cone:

// makes a cone
'use strict';
var vtk, source, mapper, actor, renderer, renderWindow, renderWindowInteractor;

vtk = require('vtk');

source = new vtk.ConeSource();
source.setResolution( 10 );

mapper = new vtk.PolyDataMapper();
mapper.setInputConnection( source.getOutputPort() );

actor = new vtk.Actor();
actor.setMapper( mapper );

renderer = new vtk.Renderer();
renderer.addActor( actor );
renderer.setBackground( 0.3, 0.2, 0.1 );
renderer.resetCamera();

renderWindow = new vtk.RenderWindow();
renderWindow.addRenderer( renderer );

renderWindowInteractor = new vtk.RenderWindowInteractor();
renderWindowInteractor.setRenderWindow( renderWindow );
renderWindowInteractor.setInteractorStyle( new vtk.InteractorStyleTrackballCamera() );

renderWindow.render();
renderWindowInteractor.start();

Note that the renderWinowInteractor.start() call does not return until the render window is closed. This means the Node.js event loop is halted during this.
