vedo 2020.4.0

Main changes

• mesh and volume data is moved from the package to vedo.embl.es/examples/data https://vedo.embl.es/examples/data/ they are downloaded on the fly and cached

• 14 new polygonized 3D fonts are available, making the old vtk default obsolete Font: Bongas Font: Calco Font: Comae Font: Glasgo Font: Inversionz Font: Kanopus Font: LionelOfParis Font: LogoType (supports Russian, Japanese and Chinese chars) Font: Normografo Font: Quikhand Font: SmartCouric Font: Theemim Font: VictorMono

  Default font is Normografo, can be changed with e.g. settings.useDefaultFont = "Theemim"

  Latex-like syntax is supported in Text() allowing to use Greek and math symbols in axes and plot titles: Type vedo -r fonts to generate the above tables.

addons:

• Ruler(): create a 3D ruler to indicate the distance of two points
• buildRulerAxes(): a new axis style (7) formed by 3 rulers
• many improvements to default axis style 1
• New axis style 11: generates a thin lined square floor

Plotter:

• show(..., newplotter=True) -> show(..., new=True)
• added methods: render(), resetCamera() and backgroundColor(c1, c2, at)
• can now change transparency using arrow keys instead of "m,./" Pressing -+ cycles through available axes styles.

utils:

• added resampleArrays()
• systemReport()
• class dotdict: A dictionary supporting dot notation.
• trimesh2vtk() -> trimesh2vedo() (check @YimingXu1213)
• vtk2trimesh() -> vedo2trimesh()

io:

• can now save and load object transformation to .mat file

mesh and pointclouds:

• coloring with pointColors() and cellColors() is merged into method cmap()
• meshes can be described by new vignette() and caption()
• useBounds() tells the camera to keep inot account mesh when resetting
• added gradient() to return the gradient of the input scalar as numpy array

shapes:

• convexHull() -> ConvexHull()
• added VedoLogo() to generate the 3D logo of the package
• major improvements to Text()
