Problem for mesh3d intensity

[ZenanH]

I'm using PlotlyJS.jl to draw my model and I chose to use mesh3d() for my task. The model is composed of tetrahedral elements, so i_1, j_1, k_1 represent the serial number of one of the triangular faces. The code reads as follows:

using PlotlyJS

trace = mesh3d(x = [...],
               y = [...],
               z = [...],
               i = [i_1, i_2, ...],
               j = [j_1, i_2, ...],
               k = [k_1, k_2, ...])

layout = Layout(...)

plot(trace, layout)

I'm not sure if there's a problem with the red area being displayed in the picture. After that, I added something about intensity:

using PlotlyJS

trace = mesh3d(x = [...],
               y = [...],
               z = [...],
               i = [i_1, i_2, ...],
               j = [j_1, i_2, ...],
               k = [k_1, k_2, ...],
               intensity = abs.(result[:,3]),
               intensitymode = "vertex",
               colorscale = "RdBu")

layout = Layout(...)

plot(trace, layout)

The same problem can be seen in the red area. It may change with perspective:

But I think maybe it should be like the picture below:

Is there anything I can do? I'm not sure what's wrong. 😅

Hi @ZenanH thanks for posting.

I'll be honest here -- I am not an expert in 3d rendering/plotting. I believe I've never even used the mesh3d method myself!

Sorry about that!

You may have better luck on the plotly discussion forum: https://community.plotly.com/

I'm going to close here as I don't believe it is an issue with this library. If I turn out to be wrong about that and there is something to fix here please feel free to re-open.
