Is it possible to create a rectilinear/structured grid from scratch by vtk.js? In C++, we can use vtkRectilinearGrid. But in official website, I haven’t found any related example.
Not as of today as we only have implemented vtkImageData and vtkPolyData. We could provide the other data structures easily but then the issue would be to render them as we will be missing the ExtractSurface filter that is used to convert any vtkDataSet into a vtkPolyData for rendering.
