Exporting scene as a glTF file

In this tutorial, we will show how to create a glTF file for a scene.

import numpy as np

from fury import actor, gltf, window
from fury.data import fetch_gltf, read_viz_gltf

Specifying centers and colors for actors. We will use these parameters later.

centers = np.zeros((3, 3))
colors = np.array([1, 1, 1])

Create a scene.

scene = window.Scene()

Creating actors and adding to scene.

cube = actor.cube(np.add(centers, np.array([2, 0, 0])), colors=colors / 2)
scene.add(cube)

sphere = actor.sphere(np.add(centers, np.array([0, 2, 0])), colors=colors)
scene.add(sphere)

fetch_gltf('BoxTextured', 'glTF')
filename = read_viz_gltf('BoxTextured')
gltf_obj = gltf.glTF(filename)
box_actor = gltf_obj.actors()
scene.add(box_actor[0])

Setting camera to the scene.

scene.set_camera(
    position=(4.45, -21, 12), focal_point=(4.45, 0.0, 0.0), view_up=(0.0, 0.0, 1.0)
)

Exporting scene as a glTF file

gltf.export_scene(scene, filename='viz_gltf_export.gltf')

Reading the newly created glTF file and get actors.

gltf_obj = gltf.glTF('viz_gltf_export.gltf')
actors = gltf_obj.actors()

Add all the actor from list of actors to the scene.

scene.add(*actors)

interactive = False

if interactive:
    window.show(scene, size=(1280, 720))

window.record(scene, out_path='viz_gltf_export.png', size=(1280, 720))
