Applying texture that is embedded within a glb model

Support

Hello everyone,

I am having a considerable amount of trouble getting vtk to render my 3d model with its textures.I am using the python module for vtk with trame.My version of vtk is 9.5.1

from trame.app import get_server

from trame.ui.vuetify import VAppLayout

from trame.widgets import vtk as tramevtk

from trame.widgets import vuetify

import vtk

import os




print(vtk.vtkVersion.GetVTKVersion())




renderer = vtk.vtkRenderer()

renderer.SetBackground(\[0.1,0.1,0.1\])

renderer.UseHiddenLineRemovalOn()

renderWindow = vtk.vtkRenderWindow()

renderWindow.AddRenderer(renderer)



renderWindowInteractor = vtk.vtkRenderWindowInteractor()

renderWindowInteractor.SetRenderWindow(renderWindow)

interactor_style = vtk.vtkInteractorStyleUser()

renderWindowInteractor.SetInteractorStyle(interactor_style)



static_folder = "../resources/models/"



importer = vtk.vtkGLTFImporter()

importer.SetFileName(os.path.join(static_folder, "reduceshuman.glb"))

importer.SetRenderWindow(renderWindow)

importer.Update()



actors = importer.GetImportedActors()

print(actors.GetNumberOfItems())

for actor in actors:

prop = actor.GetProperty()



if prop.GetNumberOfTextures() > 0:

print("Texture is applied.")

else:

print("No texture applied.")





ambient_light = vtk.vtkLight()

ambient_light.SetLightTypeToSceneLight()

ambient_light.SetColor(1.0, 1.0, 1.0)  # White light

ambient_light.SetIntensity(1.0)  # Make sure it's not too strong

renderer.AddLight(ambient_light)





renderer.ResetCamera()




\# Setup Trame

server = get_server(client_type="vue2")

ctrl = server.controller



with VAppLayout(server) as layout:

with layout.root:

with vuetify.VContainer(

fluid=True,

classes="pa-0 fill-height",

        ):

view = tramevtk.VtkLocalView(renderWindow)

ctrl.on_server_ready.add(view.update)



if \__name_\_ == "\__main_\_":

server.start()

The Model is supposed to have a yellow texture on it however currently it is completely white.
The Code does print out “Texture applied” once, which would mean that the texture is being recognized but for some reason not applied.

I would appreciate some help :slight_smile:
