brain_deer.presentation.qt.scene_3d_controls¶

Sync and route the left-panel 3D Scene controls to the selected file.

Functions¶

`active_filename`(→ str \| None)	Primary active file (dropdown / last activated in Files list).
`target_filenames`(→ list[str])	Files that Appearance / Active-Layer controls should edit.
`apply_opacity_for_file`(→ None)	Appearance opacity drives 2D + 3D for the bottom-panel active file.
`apply_global_smoothing`(→ None)	Apply surface smoothing to bottom-panel target file(s) only (not all layers).
`apply_material_to_targets`(→ None)	Store material keys on target files and push full per-file materials to 3D.
`apply_spatial_smooth_for_file`(→ None)	Debounced 3D Gaussian smoothing for scalar overlay volumes (2D + 3D).
`apply_display_resample_for_file`(→ None)	Debounced linear resample for scalar overlay display (2D slices + 3D volume).

brain_deer.presentation.qt.scene_3d_controls.active_filename(main_window) → str | None¶: Primary active file (dropdown / last activated in Files list).

brain_deer.presentation.qt.scene_3d_controls.target_filenames(main_window) → list[str]¶

Files that Appearance / Active-Layer controls should edit.

Prefer the bottom Files list multi-selection. Fall back to the primary active file when nothing is selected.

brain_deer.presentation.qt.scene_3d_controls.apply_opacity_for_file(main_window, filename: str, opacity_0_1: float, *, sync_appearance_slider: bool = True, update_2d: bool = True) → None¶: Appearance opacity drives 2D + 3D for the bottom-panel active file.

brain_deer.presentation.qt.scene_3d_controls.apply_global_smoothing(main_window, value_0_1: float) → None¶: Apply surface smoothing to bottom-panel target file(s) only (not all layers).

brain_deer.presentation.qt.scene_3d_controls.apply_material_to_targets(main_window, **kwargs) → None¶: Store material keys on target files and push full per-file materials to 3D.

brain_deer.presentation.qt.scene_3d_controls.apply_spatial_smooth_for_file(main_window, filename: str, sigma: float) → None¶: Debounced 3D Gaussian smoothing for scalar overlay volumes (2D + 3D).

brain_deer.presentation.qt.scene_3d_controls.apply_display_resample_for_file(main_window, filename: str, factor: int) → None¶: Debounced linear resample for scalar overlay display (2D slices + 3D volume).
