Vedo: How to save screenshot without show()?

[LogWell]

1. load the mesh file
2. color each face
3. save the rendered image(there's no need to show)

I don't know how to implement the above without show(), thanks~

You cannot save a screenshot without rendering the scene with show(), but you can avoiding visualizing the rendering window using keyword offscreen: e.g.

from vtkplotter import *

vp = Plotter(axes=0, offscreen=True)

for i in [1,2,3]:
    text = Text('%03d' %i, c='white')
    vp += Sphere(c=i).x(i)
    vp += text
    vp.show()
    screenshot('test_%03d.png' %i)
    vp -= text
