[BUG] Camera settings not applied when rendering scene

[heike-s]

Describe the bug
I want to create screenshots using consistent camera settings. I have a number of sets of points I would like to plot onto the mouse Nucleus Accumbens, and to make the images comparable would like to use the same camera settings to take a screenshot for each point set.

I use Shift-C to display the camera settings after adjusting to the angle that I would like to use. I then close the window, set the camera, and render the scene again. However, the brain is not displayed in the angle and orientation that I previously set up, and when checking the coordinates again using Shift-C, it returns coordinates that do not correspond to those that I set up, specifically pos, focal_point, viewup and clipping_range.

To Reproduce
`import brainrender as br
import vedo, os
vedo.settings.default_backend= 'vtk'

br.settings.SHOW_AXES = False
br.settings.ROOT_ALPHA = 0

popup_scene = br.Scene(atlas_name='allen_mouse_50um', title='Cluster 0')

front_camera = dict(
pos=(-25916.9, 6755.20, 8425.36),
focal_point=(6754.35, 5532.25, -5444.33),
viewup=(4.47401e-3, -0.995148, 0.0982831),
roll=174.709,
distance=35514.4,
clipping_range=(18770.4, 56677.3),
)

popup_scene.add_brain_region('ACB', alpha = 0.1, color = 'grey')
popup_scene.render(camera = front_camera, zoom = 5) `

Returned coordinates from Shift-C:
###################################################

Template python code to position this camera:

cam = dict(
position=(-26114.1, 5270.48, 8090.03),
focal_point=(6587.84, 3849.09, -5688.16),
viewup=(-8.83828e-4, -0.994932, 0.100542),
roll=174.703,
distance=35514.4,
clipping_range=(18744.5, 56710.0),
)
show(mymeshes, camera=cam)
###################################################

Expected behaviour
The camera settings in the camera dictionary should be applied when rendering the scene.

Screenshots
Expected plot:

Plot received:

Computer used:

• OS: macOS, M3Pro
• Version 14.2.1
• Hardware specs 18GB RAM

Additional context
I have set the following settings at the beginning of my script:
br.settings.SHOW_AXES = False
br.settings.ROOT_ALPHA = 0
The behavior persists even when not setting these variables. I also tried plotting a single hemisphere, and the behavior persists. It also persists whether I add my points or not, so for simplicity I shared the code without adding the points / points density. It also happens whether or not I use a notebook.

Thanks for reporting this @heike-s. It should now be fixed. You can install from github with pip install git+https://github.com/brainglobe/brainrender, but a new version of brainrender should be released with this fix by the end of the week.
