<p dir="auto">Hi, Three.js team.</p>
<p dir="auto">I am a fan of Three.js. I had done several successful Three.js projects.<br>
So, first of all, I would love to say, "Thank you for your dedicated library".</p>
<h5 dir="auto">Description of the problem</h5>
<p dir="auto">I know that now I am commenting duplicated issue related to VTK loader.<br>
The issue was commented in Feb, 2018. But since I VTK loading is important certainly, I decided to comment again.</p>
<p dir="auto">So, I have one VTK file generated from one external device. It has UNSTRUCTURED_GRID dataset which is not allowed yet by VTK loader. Of course, I tried to use alternative model extensions such as .fbx, .ply, etc.<br>
But unfortunately, my partners says it's a pain for them to convert current VTK to different extensions.<br>
Anyway, they provided me .ply. Its external shape looks good. But the internal shape is just empty one.</p>
<p dir="auto">This is VTK internal view:<br>

<p dir="auto">And this is PLY internal view:<br>
<a target="_blank" rel="noopener noreferrer nofollow" href="https://user-images.githubusercontent.com/52213952/92043404-5c4ef100-ed52-11ea-96a8-c3053e42a8b0.PNG"><img src="https://user-images.githubusercontent.com/52213952/92043404-5c4ef100-ed52-11ea-96a8-c3053e42a8b0.PNG" alt="ply_capture" style="max-width: 100%;"></a></p>
<p dir="auto">As you can see, their internal views are different.</p>
<p dir="auto">At the moment, I'd like to ask 2 questions:</p>
<ol dir="auto">
<li>VTK loader will never work with the rest 4 vtk datasets including  "UNSTRUCTURED_GRID"?</li>
<li>If so, how can we generate alternative model extension having same geometry as VTK?</li>
</ol>
<h5 dir="auto">Three npm version</h5>
<p dir="auto">0.120.1 latest</p>
<p dir="auto">I'd love to believe you know the solution.</p>
<p dir="auto">Thank you!</p>
<p dir="auto">I would like to ask for advice because of I have one use case where I need to load VTK file which is a BINARY DATASET STRUCTURED POINTS, which represents a segmented image.</p>
