How can I get the rgb tuple from mesh (load from .ply)? And turn off shadow when rendering points.

[CCHLENG]

I have a pointcloud save in *.ply file, now I can load and show it with load() function.

    from vedo import show, Points, load
    points = load('one-row-RGB.ply')
    points.point_size(4)   # change the size of points
    show(points).close()   # looks like rendering with shadows

I can get the XYZ data by points.points() , however, when I use points.color() , it only return [1.,1.,1.].
So how can I get the color data(rgb tuple) from the ply file?
Meanwhile, when I render the pointcloud, it looks like with shadows, which make it's hard to see the color of each point.
In Meshlab, I can close shadows manually:

With Vedo, from top side, the color is acceptable:

but from another side, it's dark. How can I make the color more clearly?

Thanks!

You can switch off lighting to have a uniform color. Try

pip install vedo -U

and

from vedo import *
pc = Points(dataurl+"debug.ply")
print(pc)
print(pc.pointdata["RGB"])  # get the point colors
pc.point_size(20).lighting("off")
show(pc)

It works! Thank you!
Where can i find it in the API Documentation? I have searched by keyword"Points"and"shadow", but I didn't find the answer.

Well "shadow" is not the right word for it.. "lighting" is :)

Get it! Thank you very much!
