Render a depth image#

Plot a depth image as viewed from a camera overlooking the “hills” example mesh.

from __future__ import annotations

import matplotlib.pyplot as plt

import pyvista as pv
from pyvista import examples

# Load an interesting example of geometry
mesh = examples.load_random_hills()

# Establish geometry within a pv.Plotter()
p = pv.Plotter()
p.add_mesh(mesh, color=True)
image depth

Record depth image without and with a custom fill value

zval = p.get_image_depth()
zval_filled_by_42s = p.get_image_depth(fill_value=42.0)

Visualize depth images

plt.colorbar(label='Distance to Camera')
plt.title('Depth image')
plt.xlabel('X Pixel')
plt.ylabel('Y Pixel')
Depth image
plt.title('Depth image (custom fill_value)')
plt.colorbar(label='Distance to Camera')
plt.xlabel('X Pixel')
plt.ylabel('Y Pixel')
Depth image (custom fill_value)
