Getting Started

Start by importing FURY.

import numpy as np
from fury import window, actor, ui, io, utils

To import a model, use io.load_polydata(). Currently supported formats include OBJ, VTK, FIB, PLY, STL and XML.

Here we are going to use suzanne model used by Blender. You can find more detail about what is suzanne model here.

We can download the model by

from fury.data import fetch_viz_models
fetch_viz_models()

The models will be downloaded in ~/.fury/models directory.

If you store the return value to models, you can find the detailed information about models in the dictionary. The directory of the suzanne model will be in models[1].

models = fetch_viz_models()
print(models[1])

To get the path of suzanne

import os
path_suzanne = os.path.join(models[1], 'suzanne.obj')
print(path_suzanne)

Now we can include the suzanne model used by Blender:

suzanne = io.load_polydata(path_suzanne)
suzanne = utils.get_polymapper_from_polydata(suzanne)
suzanne = utils.get_actor_from_polymapper(suzanne)

Set the opacity of the model:

suzanne.GetProperty().SetOpacity(0.5)

Let’s create some random variables for the cylinder parameters

centers = np.random.rand(2, 3)
directions = np.random.rand(2, 3)
heights = np.random.rand(2)
colors = np.random.rand(2, 3)

Now, we create a cylinder:

cylinders = actor.cylinder(centers, directions, colors, heights=heights)

Anything that has to be rendered needs to be added to the scene so let’s create a Scene():

scene = window.Scene()

We set the window scene variables e.g. (width, height):

showm = window.ShowManager(scene, size=(1024,720), reset_camera=False)
showm.initialize()

We add a text block to add some information:

tb = ui.TextBlock2D(position=(450, 550), font_size=23)
tb.message = "Hello Fury"

The function Scene.add() is used to add the created objects to the scene to be rendered:

scene.add(suzanne)
scene.add(cylinders)
scene.add(tb)

Start the rendering of the scene:

showm.start()
