# Examples from pyvista.PolyDataFilters.ray_trace
# ===============================================

# Compute the intersection between a ray from the origin to
# `[1, 0, 0]` and a sphere with radius 0.5 centered at the
# origin.
import pyvista as pv
sphere = pv.Sphere()
point, cell = sphere.ray_trace([0, 0, 0], [1, 0, 0], first_point=True)
f'Intersected at {point[0]:.3f} {point[1]:.3f} {point[2]:.3f}'

# Show a plot of the ray trace.
point, cell = sphere.ray_trace([0, 0, 0], [1, 0, 0], plot=True)
