how to map texture to a box mesh?

[duchaoyu]

I'm trying to map texture to a box mesh in jupyter lab, however I failed. It doesn't show the render but "Loading widget...". If I don't map the texture, and just gives the box a color, then it can be rendered. I'm not sure what's the problem and how to add texture to a mesh object properly. Thanks for all your help in advance!

Here's my code:

texture_path = 'C:\\Users\\duch\\Desktop\\jupyter_vis\\stl\\t_0007_0.jpg'
textureloader = ImageTexture(texture_path)

panel = Mesh(
    BoxBufferGeometry(585, 585, 20),
    MeshStandardMaterial(map=textureloader),
    position=[fresnel_frame.point[0] + (585/2), fresnel_frame.point[1] + (585/2) -301, fresnel_frame.point[2]-10-685]
)

camera0 = PerspectiveCamera(fov = 50, aspect=1, near = 0.1, far=2000)
key_light = DirectionalLight(position=[0, 0, 100])
ambient_light = AmbientLight()

scene0 = Scene(children=[micpts, lines, panel, ambient_light, key_light, camera0])

camera0.position= [0,0,1000]
camera0.lookAt([micpts])
camera0.up = [0,1,0]

controller0 = OrbitControls(controlling=camera0)
renderer0 = Renderer(camera=camera0, scene=scene0, controls=[controller0], width=view_width, height=view_height)

renderer0

Loading widget...

"Loading widget...".

This typically means something has gone wrong with an extension install somewhere. What does jupyter labextension list show?

Are there any errors in the browser console when running this (typically available via Ctrl + Shift + J, or alternatively F12)?

Hi, vidartf, thanks for your reply. I'm still not very sure whether there's something wrong....
