v2026.6.3

What's Changed

• add interactive widget wrappers for line, sphere, point and cylinder placement
• add Three.js scene export support
• add quaternion utilities, Gaussian cube loading, and explicit structured-grid methods
• improve CLI: Rich logging, better --search, --convert, --eog, and --run behaviour
• fix trame backend state collisions across multiple notebook views
• fix k3d backend: cell-to-point color mapping no longer mutates the original mesh
• fix NonLinearTransform.compute_main_axes: Jacobian now correct at any pivot, not just the origin
• fix LinearTransform.reorient: antiparallel case now picks a proper perpendicular axis
• fix grid_corners: wrong box positions for non-square grids when yflip=True
• fix color_map: degenerate vmax==vmin scalar path returned wrong value
• fix Minimizer: convergence check, eval() argument type, and repeated minimize() calls
• fix cart2cyl: use np.hypot to avoid overflow on large inputs
• fix write(): pipeline was attached to discarded return value instead of the object
• migrate documentation to MkDocs; refresh examples
• improve Settings.__str__ to show live values grouped by category;
  "key" in settings now works; dry_run_mode visible in print(settings)

• Fix lazy vertex normals for surface meshes by @fallenmi in #1306
• Close and orient ThickTube meshes by @antonsoo in #1311
• Fix plotter buttons with VTK 9.7 by @antonsoo in #1310
• Fix line_line_distance / segment_segment_distance TypeError by @harshajv7981 in #1313

Soft-breaking Changes

• examples under examples/other/ were moved to examples/extras/
• settings.init_colab() and Settings.start_xvfb() are now module-level functions;
  use vedo.init_colab() and vedo.start_xvfb() instead

Hard-breaking Changes

• None
