Why loader.addEventListener is not a function

Questions
1

RT
var loader = new THREE.VTKLoader();
loader.addEventListener( ‘load’, function ( event ) {})
console print loader.addEventListener is not a function

Loader in your case is not a DOM Element. Hence addEventListener is not the right thing to implement.

You can use the loader’s callback function instead.

var loader = new THREE.VTKLoader();
loader.load( url,  function ( result ) {
      console.log( result );
})

VTKLoader.js:32
scope.dispatchEvent is not a function
VTKLoader.js:107
geometry.computeCentroids is not a function

I think you are using a very old version of VTKLoader. The call to geometry.computeCentroids() was removed four years ago (see here).

Please use the current VTKLoader with latest version of three.js from the repo:

thank you
I‘m using the latest version of VTKLoader
It is the same as that

I don’t believe that. geometry.computeCentroids is not called in the latest VTKLoader.

It would be a lot easier and quick to identify the problem if you can provide a jsfiddle sample for it.

The bunny loads fine. You just applied a bad scaling to your mesh and had wrong camera settings.

BTW: I did not see any of your mentioned error messages.

Sry, I’m unable to reproduce. It works fine on my machine.

Same here. Works fine.

var loader = new THREE.VTKLoader();

loader.load("vtk/bunny.vtk",function(geometry){
	console.log(geometry)
	geometry.center();
	geometry.computeVertexNormals();
	var mesh = new THREE.Mesh( geometry, material );
	mesh.position.set( 0,0,0 );
	scene.add( mesh );
});

Interesting, what explains the gremlins that mess up the app when the OP runs the same code?
