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 Daytime Barcelona Pavilion [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 [CC-BY](https://creativecommons.org/licenses/by/2.0/) license. ## Head 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. Model thanks to Infinite Realities, Inc., [CC-BY](https://creativecommons.org/licenses/by/2.0/) license. Environment map thanks to [USC-ICT light probe image gallery](http://gl.ict.usc.edu/Data/HighResProbes/). ## Killeroos Coated Gold Killeroo [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 Landscape [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 Measured blue vinyl wrap [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. Thanks to Yasutoshi Mori (@MirageYM) for this model; [CC-BY](https://creativecommons.org/licenses/by/2.0/) license. ## San Miguel San Miguel courtyard [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 Smoke plume with sphere [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 Sportscar [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). This excellent model and pbrt conversion courtesy of Yasutoshi Mori (@MirageYM); [CC-BY](https://creativecommons.org/licenses/by/2.0/) license. ## Transparent Machines Frame 812 [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).

Many thanks to Florent Boyer for this scene. ## Zero Day Zero Day, Measure One, Frame 180 [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!) [License](http://beeple-crap.com/resources.php).
