Quick start¶

import pyvista as pv
from pyvista import examples

pl = pv.Plotter(off_screen=True, window_size=(1920, 1080))
pl.add_mesh(
    examples.download_bunny(),
    color="lightgrey",
    pbr=True, metallic=0.1, roughness=0.4,
)
pl.add_light(pv.Light(position=(5, -5, 5), light_type="scene light"))
pl.camera_position = "iso"

pl.blender.render("bunny.png", samples=128)

Render quality scales with samples. 32 for previews, 128 – 512 for publication-quality output. With OptiX denoising (default), 64 samples is usually visually clean.

Animation¶

import numpy as np

trajectory = np.load("frames.npz")

def updater(t: int) -> None:
    mesh.points = trajectory[t]

pl.blender.animate("out.mp4", updater=updater, frames=range(120), fps=30)

Interactive rendered viewport¶

pl.blender.show()   # one window, mouse rotates / zooms, Cycles renders in real-time

See Architecture for the design of the single-window overlay and the three-tier sample regime.
