# Animation
# =========

# This example demonstrates how to create a simple animation.
# A timer is used with `add_timer_event()`
# to move a sphere across a scene.
# Inspired by VTK Animation Examples.
import pyvista as pv

sphere = pv.Sphere()

pl = pv.Plotter()
actor = pl.add_mesh(sphere)


def callback(step):
    actor.position = [step / 100.0, step / 100.0, 0]


pl.add_timer_event(max_steps=200, duration=500, callback=callback)

cpos = pv.CameraPosition(
    position=(0.0, 0.0, 10.0), focal_point=(0.0, 0.0, 0.0), viewup=(0.0, 1.0, 0.0)
)
pl.show(cpos=cpos)
