SpinBox UI

This example shows how to use the UI API. We will demonstrate how to create a SpinBox UI.

First, some imports.

import numpy as np

import fury

First we need to fetch some icons that are included in FURY.

fury.data.fetch_viz_icons()

Data size is approximately 12KB
Dataset is already in place. If you want to fetch it again please first remove the folder /Users/skoudoro/.fury/icons

({'icomoon.tar.gz': ('https://digital.lib.washington.edu/researchworks/bitstream/handle/1773/38478/icomoon.tar.gz', 'BC1FEEA6F58BA3601D6A0B029EB8DFC5F352E21F2A16BA41099A96AA3F5A4735')}, '/Users/skoudoro/.fury/icons')

Let’s create a Cone.

cone = fury.actor.cone(
    centers=np.random.rand(1, 3),
    directions=np.random.rand(1, 3),
    colors=(1, 1, 1),
    heights=np.random.rand(1),
)

Creating the SpinBox UI.

spinbox = fury.ui.SpinBox(
    position=(200, 100),
    size=(300, 100),
    min_val=0,
    max_val=360,
    initial_val=180,
    step=10,
)

Now that all the elements have been initialised, we add them to the show manager.

current_size = (800, 800)
show_manager = fury.window.ShowManager(size=current_size, title="FURY SpinBox Example")

show_manager.scene.add(cone)
show_manager.scene.add(spinbox)

Using the on_change hook to rotate the cone.

# Tracking previous value to check in/decrement.
previous_value = spinbox.value


def rotate_cone(spinbox):
    global previous_value
    change_in_value = spinbox.value - previous_value
    fury.utils.rotate(cone, (change_in_value, 1, 0, 0))
    previous_value = spinbox.value


spinbox.on_change = rotate_cone

Starting the ShowManager.

interactive = False

if interactive:
    show_manager.start()

fury.window.record(show_manager.scene, size=current_size, out_path="viz_spinbox.png")

/opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/sphinx_gallery/gen_rst.py:722: UserWarning: We'll no longer accept the way you call the record function in future versions of FURY.

Here's how to call the Function record: record(scene='value', cam_pos='value', cam_focal='value', cam_view='value', out_path='value', path_numbering='value', n_frames='value', az_ang='value', magnification='value', size='value', reset_camera='value', screen_clip='value', stereo='value', verbose='value')
