2023.5.0

Main changes

Major internal refactoring.

Breaking changes

• rename internal list plt.actors which now become plt.objects
• rename .points() to property .vertices. Hence:
  mesh.points() -> mesh.vertices
mesh.points(newpoints) -> mesh.vertices = newpoints
• rename .cell_centers() to property .cell_centers
• rename .faces() to property .cells
• rename .lines() to property .lines
• rename .edges() to property .edges
• rename .normals() and split it into property .vertex_normals and property .cell_normals
• rename picture.Picture2D(...) which becomes Image(...).clone2d() (see examples/pyplot/embed_matplotlib.py).
• rename Volume.probe_points() which becomes points.probe(volume)
• rename Volume.probe_line() which becomes line.probe(volume)
• rename Volume.probe_plane() which becomes plane.probe(volume)
• rename file_io.load_transform(). LinearTransform("file.mat") substitutes it.
• rename transform_with_landmarks() to align_with_landmarks()
• rename find_cells_in() to find_cells_in_bounds()
• rename mesh.is_inside(pt) moved to mesh.contains(pt)
• rename Slicer2DPlotter moved to application module.Slicer2DPlotter
• rename and moved method voronoi() to points.generate_voronoi()
• rename class Ruler to Ruler3D

Other changes

• improvements in how vtk classes are imported (allow lazy import)
• improvements to method mesh.clone2d()
• improvements in Slicer3DPlotter thanks to @daniel-a-diaz in #925
• improvements in applications.Browser
• add new vedo.transformations.py module.
• add plotter.pick_area() thanks to @ZiguoAtGitHub and @RubendeBruin feedback.
• add texture to npz files thanks to @zhouzq-thu in #918
• add background radial gradients
• add utils.line_line_distance() function
• add utils.segment_segment_distance() function
• add plotter.initialize_interactor() method
• add object hinting by hovering mouse (see flag_labels1.py)
• add colors.lut_color_at(value) the color of the lookup table at value.
• add .show(..., screenshot="myfile.png") keyword
• add object.coordinates same as object.vertices
• add move() to move single points or objects
• add copy() as alias to clone()
• add "Roll" to camera dictionary (thanks @baba-yaga )
• add applications.Slicer3DTwinPlotter thanks to @daniel-a-diaz
• add radii feature to smooth_mls_2d() by @jo-mueller (now store results in arrays mesh.pointdata['MLSVariance'] and mesh.pointdata['MLSValidPoint'])
• passing a vtkCamera to show(camera=...) triggers a copy of the input which is therefore not muted by any subsequent interaction (thanks @baba-yaga )

Bug Fixes

• bug fix in closest_point() thanks to @goncalo-pt
• bug fix in tformat thanks to @JohnsWor in #913
• bug fix in windows OS in timers callbacks thanks to @jonaslindemann
• bug fix to non linear tranforms mode. Now it can be instantiated with a dictionary
• bug fix in meshlab interface thanks to @JeffreyWardman in #924
• bug fix changed mp = matplotlib.colormaps[name] in colors.py
