No support for quarternion in vtk.js?

Dear forum,

I have a VTP file that I am visualising with the Glyph3DMapper and glyphs. The glyphs are oriented using quarternions, with I can select and see in Paraview without problems.

In VTK.js however there seems to be no such option, only Direction, Matrix, and Rotation. Glyph3DMapper | vtk.js

How would I go about recreating my visualisation in VTK.js? I have most things working except the orientation.

Many thanks for the help,

You can use quat from gl-matrix (which is also used internally in vtk.js) to move between quaternions and matrices. Adding support for quaternions would be redundant.
