Browser

vedo.applications.Browser(meshes, sliderpos=((0.55, 0.07), (0.96, 0.07)), c=None, prefix='')

Generate a Plotter window to browse a list of objects using a slider. Returns the Plotter object.

FreeHandCutPlotter

class vedo.applications.FreeHandCutPlotter(mesh, splined=True, font='Bongas', alpha=0.9, lw=4, lc='red5', pc='red4', c='green3', tc='k9', tol=0.008)

Bases: vedo.plotter.Plotter

A Plotter derived class which edits polygonal meshes interactively. Can also be invoked from command line. E.g. with

vedo --edit https://vedo.embl.es/examples/data/porsche.ply

Usage:

• Left-click and hold to rotate

• Right-click and move to draw line

• Second right-click to stop drawing

• Press c to clear points

• z/Z to cut mesh (Z inverts inside-out the selection area)

• L to keep only the largest connected surface

• s to save mesh to file (tag _edited is appended to filename)

• u to undo last action

• h for help, i for info

Parameters

• mesh (Mesh, Points) – The input Mesh or pointcloud.

• splined (bool, optional) – join points with a spline or a simple line. The default is True.

• font (str, optional) – Font name for the instructions. The default is “Bongas”.

• alpha (float, optional) – transparency of the instruction message panel. The default is 0.9.

• lw (str, optional) – selection line width. The default is 3.

• lc (str, optional) – selection line color. The default is “red5”.

• pc (str, optional) – selection points color. The default is “black”.

• c (str, optional) – backgound color of instructions. The default is “green3”.

• tc (str, optional) – text color of instructions. The default is “white”.

• tol (int, optional) – tolerance of the point proximity. Default is 5.

IsosurfaceBrowser

vedo.applications.IsosurfaceBrowser(volume, c=None, alpha=1, lego=False, cmap='hot', pos=None)

Generate a Plotter window for Volume isosurfacing using a slider. Returns the Plotter object.

Example

from vedo import dataurl, Volume
from vedo.applications import IsosurfaceBrowser
vol = Volume(dataurl+'head.vti')
plt = IsosurfaceBrowser(vol, c='gold')
plt.show(axes=7, bg2='lb')

RayCastPlotter

vedo.applications.RayCastPlotter(volume)

Generate a Plotter window for Volume rendering using ray casting. Returns the Plotter object.

Slicer2d

vedo.applications.Slicer2d(volume, levels=(None, None), size=(900, 900), bg='k9', zoom=1.2)

Create a 2D window with a single slice of a Volume, wich can be oriented arbitrarily in space.

Parameters

wl (list) – window and color levels

SlicerPlotter

vedo.applications.SlicerPlotter(volume, alpha=1, cmaps=('gist_ncar_r', 'hot_r', 'bone_r', 'jet', 'Spectral_r'), map2cells=False, clamp=True, useSlider3D=False, size=(1200, 1000), screensize='auto', title='', bg='white', bg2='lightblue', axes=7, showHisto=True, showIcon=True, draggable=False, verbose=True)

Generate a Plotter window with slicing planes for the input Volume. Returns the Plotter object.

Parameters

• alpha (float) – transparency of the slicing planes

• cmaps (list) – list of color maps names to cycle when clicking button

• map2cells (bool) – scalars are mapped to cells, not intepolated.

• clamp (bool) – clamp scalar to reduce the effect of tails in color mapping

• useSlider3D (bool) – show sliders attached along the axes

• size (list) – rendering window size in pixels

• screensize (list) – size of the screen can be specified

• title (str) – window title

• bg – background color

• bg2 – background gradient color

• axes (int) – axis type number

• showHisto (bool) – show histogram on bottom left

• showIcon (bool) – show a small 3D rendering icon of the volume

• draggable (bool) – make the icon draggable
