vtkGLTFReader unable to read data from .glb files

Development
5

I used to receive this as warning in 9.1.0 but I was able to render the glb file in the 9.1.0. Heres the pipeline I used in 9.1.0. It is same as the one above but it had vtkCleanPolyData too.


def render_gltf(input_filename):
    # Read PolyData
    reader = vtk.vtkGLTFReader()
    reader.SetFileName(input_filename)
    reader.Update()
    
    #  Remove any duplicate points.
    cleanfilter = vtk.vtkCleanPolyData()
    cleanfilter.SetInputConnection(reader.GetOutputPort())
    cleanfilter.Update()
    
    # Convert to polydata
    polydata = vtk.vtkCompositeDataGeometryFilter()
    polydata.SetInputConnection(cleanfilter.GetOutputPort())
    polydata.Update()
    
    # Create a mapper
    mapper = vtk.vtkPolyDataMapper()
    mapper.SetInputConnection(polydata.GetOutputPort())
    
    # Create an actor
    actor = vtk.vtkActor()
    actor.SetMapper(mapper)
    
    # Create a renderer
    renderer = vtk.vtkRenderer()
    renderer.SetBackground(0.1, 0.1, 0.1)
    
    # Create a render window
    render_window = vtk.vtkRenderWindow()
    render_window.SetWindowName("GLTF Example")
    render_window.SetSize(800, 600)
    render_window.AddRenderer(renderer)
    
    # Create a render window interactor
    render_window_interactor = vtk.vtkRenderWindowInteractor()
    render_window_interactor.SetRenderWindow(render_window)
    
    # Add the actor to the renderer
    renderer.AddActor(actor)
    
    # Set up camera and render
    renderer.ResetCamera()
    render_window.Render()
    
    # Start the rendering loop
    render_window_interactor.Start()

if __name__ == "__main__":
    input_file = r"path\to\Archvis_Empty.glb"# Replace with the path to your input gltf file


    render_gltf(input_file)type or paste code here
