Hi James,<br>
<br>
Sorry for the late response. actually I created the JSON file using
the points extracted from VTK dicom data.<br>
Please find the attached files for the Java method I used and
required Json_simple-1.1.jar file.<br>
<br>
I hope this will be easy and helpful for you.<br>
<br>
Regards,<br>
Sathish<br>

these works are really interesting and promising.<br>
<br>
<br>
Thank you to report this here.<br>
<br>
On my side, I'm working with VTK and recently I was trying
WebGL. Despite compatibility issues, WebGL works great.<br>
<br>
I have been able to load and render STL files.<br>
<br>
I'm going to look at xTK which seems really promising.<br>
<br>
By the way, is there any simple way to create JSON files from
VTK or STL files ?<br>
<br>
<br>
Best<br>
