Rendering rectilinear grids in vtk files with vtk.js not working.

Im trying to render out data inside a rectilinear grid that is inside a vtk file following these 2 examples separately .
https://kitware.github.io/vtk-js/examples/VolumeMapper.html
https://kitware.github.io/vtk-js/examples/PolyDataReader.html

The renderer works but then the screen is black and nothing works or shows up at all.

I'm using react and that seems to be handling vtk.js just fine.

Ok, not sure to understand the question, but vtkRectilinearGrid is not directly supported as a renderable format. Some processing will need to happen in order to extract its vtkPolyData representation.
