Awesome
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!
Barcelona Pavilion
<img alt="Daytime Barcelona Pavilion" src="images/barcelona-pavilion/pavilion-day.png" height="400"/>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.
Bistro
<img alt="Bistro" src="images/bistro/bistro_vespa.png" height="400"/>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.
BMW M6
<img alt="BMW M6" src="images/bmw-m6/bmw-m6.png" height="400"/>This nice model of a BMW M6 automobile is thanks to tyrant monkey from Blend Swap. CC Zero (Public Domain) license.
Bunny Cloud
<img alt="Bunny cloud" src="images/bunny-cloud/bunny-cloud.png" height="400"/>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.
Bunny Fur
<img alt="Bunny fur" src="images/bunny-fur/bunny-fur.png" height="400"/>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.
Contemporary Bathroom
<img alt="Contemporary Bathroom" src="images/contemporary-bathroom/contemporary-bathroom.png" height="400"/>A model of a contemporary bathroom, courtesy of Mareck via Blend Swap. CC Zero (Public Domain) license.
Crown
<img alt="Crown" src="images/crown/crown.png" height="400"/>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/).
Dam Break
<img alt="Dam break" src="images/dambreak/dambreak0.png" height="400"/>Two frames of a fluid simlulation from Yining Karl Li's nifty Ariel fluid simulator.
Disney Cloud
<img alt="Disney Cloud" src="images/disney-cloud/disney-cloud-hd.png" height="400"/>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.
Explosion
<img alt="Explosion" src="images/explosion/explosion.png" height="400"/>A volumetric fiery explosion, stored in a NanoVDB volume that was converted from an OpenVDB volume from the OpenVDB repository.
Ganesha
<img alt="Ganesha" src="images/ganesha/ganesha.png" height="400"/>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.
Hair
<img alt="Hair" src="images/hair/hair-actual-bsdf.png" height="400"/>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.

Head
<img alt="Head" src="images/head/head.png" height="400"/>Human head model with a realistic BSSRDF, showing the effect of subsurface scattering.

Killeroos
<img alt="Coated Gold Killeroo" src="images/killeroos/killeroo-coated-gold.png" height="400"/>The classic "killeroo" model, with a variety of materials and in a variety of settings.
Thanks to headus for the model.
Kroken
<img alt="Kroken Interior" src="images/kroken/camera-1.png" height="400"/>A complex modern interior scene, new for pbrt-v4.
This scene was licensed from Angelo Ferretti and is available in pbrt's scene description format under a CC-BY-ND license.
Landscape
<img alt="Landscape" src="images/landscape/view-0.png" height="400"/>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.
Many thanks to Jan-Walter Schliep, Burak Kahraman, and Timm Dapper from Laubwerk for this amazing scene, which is licensed under a CC-BY license.
LTE Orb
<img alt="Measured blue vinyl wrap" src="images/lte-orb/lte-orb-blue-agat-spec.png" height="400"/> <img alt="" src="images/lte-orb/lte-orb-simple-ball.png" height="400"/>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.)

PBRT Book
<img alt="pbrt book" src="images/pbrt-book/book.png" height="400"/>A realistic model of the second edition of the Physically Based Rendering book.

Sportscar
<img alt="Sportscar" src="images/sportscar/sportscar-sky.png" height="400"/>Sportscar model, where nearly every surface uses a measured BRDF from the RGL Material Database.
