Yes you can create an Assembly: ```py assem = myline + myobj show(assem) ```

Did you manage to do it?

You can create a picture-in-picture rendering with any sort of 3d object or axes. This is a good example to start with https://github.com/marcomusy/vedo/blob/master/examples/other/inset.py https://github.com/marcomusy/vedo/tree/master/examples/other/icon.py https://github.com/marcomusy/vedo/tree/master/examples/volumetric/slicer1.py

No, `mesh.vertices ` will hold the new coordinates after `.apply_transform(T)`

try to use the dev version with ``` pip install -U git+https://github.com/marcomusy/vedo.git ```

Thanks for reporting this... it's a funny thing that vtk cannot read a vtu file :( I need to check why that happens...

From the error messages above it looks that the reader cannot pick `/projects/.cache/vedo/RectilinearGrid.vtr` from https://vedo.embl.es/examples/data/RectilinearGrid.vtr ..but it works fine with `/projects/.cache/vedo/embryo.tif` so i'm a bit confused as to why that...

I think a -1 is needed in the above. Anyway consider the following: https://en.wikipedia.org/wiki/Reeb_graph ```py from vedo import * mesh = Mesh("https://discourse.paraview.org/uploads/short-url/qVuZ1fiRjwhE1qYtgGE2HGXybgo.stl") mesh.rotate_x(10).rotate_y(15).alpha(0.5) mesh.pointdata["scalars"] = mesh.vertices[:, 0] printc("is_closed :", mesh.is_closed())...

Consider the following example: ```py import vedo import numpy as np vedo.settings.default_backend = "vtk" vedo.settings.immediate_rendering = False meshes = [vedo.Ellipsoid().color(i) for i in range(30)] num_meshes = len(meshes) plt = vedo.Plotter(N=num_meshes,...

Uhm.. does it also crash in the latest dev? ``` pip install -U git+https://github.com/marcomusy/vedo.git ```
