This repository provides the following scenes for use with pbrt-v4. We will be adding more scenes in the coming weeks and would happily accept contributions of additional ones!
A model of van der Rohe's classic Barcelona Pavilion, including both daytime and nighttime lighting setups. In the daytime setup, all illumination comes from a realistic sky model encoded in an HDR environment map. The night model has a very dark sky map and a number of area light sources; it is particularly challenging to render, as much of the illumination travels through one or more layers of glass before hitting a surface.
Thanks to Hamza Cheggour, who created this great model and made it available via a CC-BY license.
Amazon Lumberyard's "Bistro" model, featuring a detailed model of a Parisian street. This model is via NVIDIA's Open Research Content Archive (ORCA) and is licensed under a CC-BY license.
This nice model of a BMW M6 automobile is thanks to tyrant monkey from Blend Swap. CC Zero (Public Domain) license.
The classic Stanford bunny model, remade using volumetric media to give it a cloud-like appearance. The bunny is stored in a NanoVDB volume that was converted from an OpenVDB volume from the OpenVDB repository.
The Stanford bunny model, now covered in fur that is modeled using pbrt's curve shape for its geometry and pbrt's hair BSDF for its reflection. This scene is computationally challenging to render, requiring long light paths in difficult-to-intersect geometry.

Detailed model of the Austrian Imperial Crown, featuring an accurate reflection model for the gold metal surfaces, and many gems that refract light passing through them.
This amazing model was created by Martin Lubich (http://www.loramel.net/).
Two frames of a fluid simlulation from Yining Karl Li's nifty Ariel fluid simulator.
The cloud from the dataset provided by Disney (see here).
The original dataset includes the HD render computed with Disney's Hyperion, and the cloud density field voxelized at different resolutions and stored in OpenVDB volumes. It also includes a Mitsuba scene description file and the associated SD render computed with it. The original dataset is Copyright 2017 Disney Enterprises, Inc. and is licensed under the CCA-SA 3.0 Licence. The volumetric cloud model used for reference is a photograph by Kevin Udy provided on the Colorado Clouds Blog and licensed under the CCA-SA 3.0 Licence.
The voxelized density field is stored in a NanoVDB volume that was converted from the OpenVDB "quarter" resolution volume due to github's limitations on file size; it can easily be replaced with higher-resolution versions downloaded from Disney's website.
A volumetric fiery explosion, stored in a NanoVDB volume that was converted from an OpenVDB volume from the OpenVDB repository.
Very detailed scan of a small statue with over 4.3 million triangles, illuminated by a few area light sources.
Model scanned by Wenzel Jakob.
Geometric hair models lit by an environment map, showing the effect of
rendering using pbrt's HairBxDF scattering model with parameters that
simulate various types of hair.

Human head model with a realistic BSSRDF, showing the effect of subsurface scattering.

The classic "killeroo" model, with a variety of materials and in a variety of settings.
Thanks to headus for the model.
A complex modern interior scene, new for pbrt-v4.

Complex realistic outdoor landscape scene,
featuring 23,241 unique plant models. Thanks to object instancing, the
scene has a total geometric complexity of 3.1 billion triangles, even
though only 24 million triangles need to be stored in memory. view-0.pbrt
is the cover image of the third edition of the Physically Based Rendering
book.

Spherical orb with an inset spherical object. The geometric structure of the shapes involved provides a useful tool for visualizing the appearance of various materials. (A simplified version of the scene without the light transport equation is also available.)

A realistic model of the second edition of the Physically Based Rendering book.
Thanks to Karl Li (@yiningkarlli) for this fun model.
A complex model inspired by a hotel in San Miguel de Allende, Mexico.
Thanks to Guillermo M. Leal Llaguno for this excellent scene.
A smoke simulation around an obstacle using volume data generated using the simulator published with Kim et al.'s Wavelet Turbulence for Fluid Simulation paper.
Sportscar model, where nearly every surface uses a measured BRDF from the RGL Material Database.

Dragon model rendered with subsurface scattering, where multiple scene description files show the visual effect of changing the density of the scattering medium.
Dragon model courtesy Stanford Computer Graphics Laboratory. Environment map thanks to Bernhard Vogl.
A variety of detailed glass shapes illuminated by skylight. For good results, upwards of 64 ray bounces are required.
Models are from frames of @beeple's amazing Transparent Machines video.
Modern indoor environment.
Many thanks to Florent Boyer for this scene.

A number of frames converted from Beeple's amazing Zero-Day animation. Converted from Cinema4D files downloaded from Beeple's website. (Note that the original materials and lighting is much better--improvements to our conversion gratefully received!)
