Hi, first off ,thanks for using vtkplotter! 😃 I went through the examples and I found a bunch of possible problems:

in Example/Cells.ipynb Cells_err1

in Misc.ipynb no slider is shoowing in the rendering window Misc_noslider (this might be due to my local version of vtkplotter, I might have broken some functionality…)

In Regions.ipynb: Regions Also update_folder doesn’t seem to exist…

In Video.ipynb i get: Video

Besides, I have a few suggestions to maybe improve the interface i.e.

  • can add rendering window titles with Plotter(title='BrainRender version x.x')
  • consider Plotter shape descriptors “1|3”, “3|1”, “2/3”, this is a new feature that allows to subdivide rendering spaces asymmetrically.
  • can set position of the Scene / Plotter instance with Plotter(pos=(x_screen,y_screen)` when having multiple windows
  • Some examples take quite a long to download + render, maybe it is a good idea to indicate in the example the approx time for the user to wait or use a ProgressBar
  • the iconized whole brain (very nice idea btw!) shows up a bit too high in the rendering window
  • add some method to close window (maybe a button with status color, or a scene.close() method). I;m not sure if there is the possibility to disable ‘q’ on keyboard as this hangs the execution…
  • Neuron.ipynb takes ages to load a nr of neurons… maybe could be made faster by reducing the amount of stuff to download, or is it expected or necessary at all?
  • Consider not rendering the empty Scene() when creating the instance, as probably it is not necessary…

ignore any of these which you consider irrelevant or let me know if you need clarifications or help 😃 Cheers Marco

Hi Marco, sorry to bother you again.

Could you have a look at https://github.com/BrancoLab/BrainRender/issues/18#issue-536468176 when you have a moment?

It seems that when multiple scenes are created one after the other, the actors are upside down from the second scene onwards. I don’t think that this has anything to do with brain render per se, but I can’t tell what’s causing this either. If you could look into it that would be awesome, as the current fix for it is suboptimal.

Hi Marco,

The errors in the examples should be fixed now. Thank you again for spotting them and reporting them!

Cheers, Fede
