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

import fury

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 = fury.window.Scene()

Creating actors and adding to scene.

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

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

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

Here's how to call the Function fetch_gltf: fetch_gltf(name='value', mode='value')

  exec(self.code, self.fake_main.__dict__)

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

fury.gltf.export_scene(scene, filename="viz_gltf_export.gltf")

Reading the newly created glTF file and get actors.

gltf_obj = fury.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:
    fury.window.show(scene, size=(1280, 720))

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

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')

  exec(self.code, self.fake_main.__dict__)
