Hello! I am trying to plot a 3D medical image, so I get an image like that [image] This is my code: [image] How do I get a different angle of light to see the contrast better?

@phungkien2001 It is recommended to use go.Mesh3d to plot meshes. figure_factory.create_trisurfis obsolete. It was defined a few years before go.Mesh3d. In addition to setting lighting and lightposition, you can also try setting flatshading=True, in the go.Mesh3d instance, like here: https://c…

Hi, here is a example you could try: [image] How to do backface culling when rendering Mesh3d 📊 Plotly Python Hi @danielyan86129 are you referring to this? In my experience it sometimes helps, playing with the lightning (example code from one of my experiments): …

Why I can’t use fig.update(lighting) ?

@empet Thanks a lot for your reply. In figure_factory.create_trisurf have a function-like ‘simples’, so what is the alternative in go-mesh3D?

@phungkien2001 simplices is an array of ints of shape (n, 3). The lists ( arrays) of i, j, k from go.Mesh3d definition are: i, j,k = simplices.T See here https://chart-studio.plotly.com/~empet/15522 how trisurfs are defined and plotted as go.Mesh3d instances.

Your answer is so amazing !!! Thank you so much.
