A python module for scientific analysis and visualization of эd objects

Features

Download & Install

pip install

Quick Start



To visualize a file from a web URL (or from your Dropbox!), simply type in your terminal:

pip install vedo
vedo https://vedo.embl.es/examples/data/panther.stl.gz
vedo_cli_panther

To visualize a full 3D interactive scene, type:

vedo https://vedo.embl.es/examples/geo_scene.npz
geological_model


Let's create an interactive 3D scene with a simple cone, in 3 lines of python code:

from vedo import Cone

# Create a simple cone
c = Cone()

# Show it (with axes)
c.show(axes=1)


# Now you can interact with the 3D scene,
# Press "h" and explore the possibilities! 
cone

Let's write a simple python script that loads a polygonal Mesh and generates a cool rendering by adding some custom light sources to the scene:

from vedo import *

# Load a polygonal mesh, make it white and glossy:
man = Mesh('https://vedo.embl.es/examples/data/man.vtk')
man.c('white').lighting('glossy')

# Create two points:
p1 = Point([ 1,0,1], c='yellow')
p2 = Point([-1,0,2], c='red')

# Add colored light sources at the point positions:
l1 = Light(p1, c='yellow')
l2 = Light(p2, c='red')

# Show everything in one go:
show("Hello World", man, l1, l2, p1, p2, axes=True)

Let's create a Volume, a volumetric dataset, from a numpy array:

import numpy as np
from vedo import *

# Create a scalar field: the distance from point (15,15,15)
X, Y, Z = np.mgrid[:30, :30, :30]
scalar_field = ((X-15)**2 + (Y-15)**2 + (Z-15)**2)/225

# Create the Volume from the numpy object
vol = Volume(scalar_field)

# Generate the surface that contains all voxels in range [1,2]
lego = vol.legosurface(1,2).cmap("afmhot_r").add_scalarbar()

show(lego, axes=True)
