Ray Tracing#

Single line segment ray tracing for PolyData objects.

poly ray trace
from __future__ import annotations

import pyvista as pv

# Create source to ray trace
sphere = pv.Sphere(radius=0.85)

# Define line segment
start = [0, 0, 0]
stop = [0.25, 1, 0.5]

# Perform ray trace
points, ind = sphere.ray_trace(start, stop)

# Create geometry to represent ray trace
ray = pv.Line(start, stop)
intersection = pv.PolyData(points)

# Render the result
p = pv.Plotter()
p.add_mesh(sphere, show_edges=True, opacity=0.5, color="w", lighting=False, label="Test Mesh")
p.add_mesh(ray, color="blue", line_width=5, label="Ray Segment")
p.add_mesh(intersection, color="maroon", point_size=25, label="Intersection Points")
