... and return a meaningful JS Object representation.

Hi all, I also eagerly need this feature. Is there any progress on this issue and how could I give help to this? After some search, I didn't find any web-based DICOM 3D viewer support this kind of file, and then finally found out some light, which is converting DICOM-RT files into STL or PLY files first, and loading them into three.js. This is the best way so far I've figured out.
