[vtkusers] WebGL 3D Viewer Demo

[Daniel Haehn]

Hi guys,

this is all very exciting and looks great!

Also, checkout XTK: http://goXTK.com

For example, with XTK it is possible to display a (ascii) .vtk file
with the following javascript snippet:

...
// create a new renderer
var r = new X.renderer('r');
r.init();

// load a .vtk file
var skull = new X.object();
skull.load('skull.vtk');

// add the object
r.add(skull);

// .. and render it
r.render();
...

Cheers,
Daniel
