This repository provides the following scenes for use with
[pbrt-v4](https://github.com/mmp/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"/>

[barcelona-pavilion/](https://github.com/mmp/pbrt-v4-scenes/tree/master/barcelona-pavilion/)

A model of van der Rohe's classic [Barcelona
Pavilion](https://en.wikipedia.org/wiki/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](http://www.emirage.org), who created this [great
model](http://www.emirage.org/2013/04/24/free-download-archviz-project-pabellon-barcelona-3d-scene-v1-2-updated/)
and made it available via a

## Head

[head/](https://github.com/mmp/pbrt-v4-scenes/tree/master/head/)

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"/>

[killeroos/](https://github.com/mmp/pbrt-v4-scenes/tree/master/killeroos/)

The classic "killeroo" model, with a variety of materials and in a variety
of settings.

Thanks to [headus](http://www.headus.com/au)/Rezard for the model.

## Landscape

<img alt="Landscape" src="images/landscape/view-0.png" height="400"/>

[landscape/](https://github.com/mmp/pbrt-v4-scenes/tree/master/landscape/)

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](http://www.laubwerk.com) for this amazing scene.

## LTE Orb

<img alt="Measured blue vinyl wrap" src="images/lte-orb/lte-orb-blue-agat-spec.png" height="400"/>

[lte-orb/](https://github.com/mmp/pbrt-v4-scenes/tree/master/lte-orb/)

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.

## San Miguel

<img alt="San Miguel courtyard" src="images/sanmiguel/sanmiguel-courtyard-second.png" height="400"/>

[sanmiguel/](https://github.com/mmp/pbrt-v4-scenes/tree/master/sanmiguel/)

A complex model inspired by a hotel in San Miguel de
Allende, Mexico.

Thanks to Guillermo M. Leal Llaguno for this excellent scene.

## Smoke Plume

<img alt="Smoke plume with sphere" src="images/smoke-plume/plume.png" height="400"/>

[smoke-plume/](https://github.com/mmp/pbrt-v4-scenes/tree/master/smoke-plume/)

A smoke simulation around an obstacle using volume data generated using the
simulator published with Kim et al.'s [Wavelet Turbulence for Fluid
Simulation](https://www.cs.cornell.edu/~tedkim/wturb/) paper.

## Sportscar

<img alt="Sportscar" src="images/sportscar/sportscar-sky.png" height="400"/>

[sportscar/](https://github.com/mmp/pbrt-v4-scenes/tree/master/sportscar/)

Sportscar model, where nearly every surface uses a measured BRDF from the
[RGL Material Database](http://rgl.epfl.ch/materials).

## SSS Dragon

<img alt="Dragon" src="images/sssdragon/dragon_10.png" height="400"/>

[sssdragon/](https://github.com/mmp/pbrt-v4-scenes/tree/master/sssdragon/)

Dragon model rendered with subsurface scattering, where multiple scene
description files show the visual effect of changing the density of the
scattering medium.

Laboratory](http://graphics.stanford.edu/data/3Dscanrep/).  Environment map

## Transparent Machines

<img alt="Frame 812" src="images/transparent-machines/frame812.png" height="400"/>

[transparent-machines/](https://github.com/mmp/pbrt-v4-scenes/tree/master/transparent-machines/)

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](http://beeple-crap.com)'s amazing
[Transparent Machines
video](https://vimeo.com/78716671).

## Villa

<img alt="Daylight villa" src="images/villa/villa-daylight.png" height="400"/>

[villa/](https://github.com/mmp/pbrt-v4-scenes/tree/master/villa/)

Modern indoor environment.

Many thanks to Florent Boyer for this scene.

## Zero Day

<img alt="Zero Day, Measure One, Frame 180" src="images/zero-day/frame180.png" height="400"/>

[zero-day/](https://github.com/mmp/pbrt-v4-scenes/tree/master/zero-day/)

A number of frames converted from Beeple's amazing
[Zero-Day](https://vimeo.com/140163198) animation. Converted from Cinema4D
files downloaded from [Beeple's
website](http://www.beeple-crap.com/resources.php). (Note that the original
materials and lighting is much better--improvements to our conversion
gratefully received!)
