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](images/barcelona-pavilion/pavilion-day.png) barcelona-tavilion/ 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](images/head/head.png) 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](images/killeroos/killeroo-coated-gold.png) killeroos/ The classic "killeroo" model, in a variety of settings. Thanks to [headus](http://www.headus.com/au)/Rezard for the model. == Landscape == ![Landscape](images/landscape/view-0.png) 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](images/lte-orb/lte-orb-blue-agat-spec.png) 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](images/sanmiguel/sanmiguel-courtyard-second.png) 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](images/smoke-plume/plume.png) 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 == ![](images/sportscar/sportscar.png height="200px") 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. == SSS Dragon == ![](images/sssdragon/dragon_10.png) sssdragon/ 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](http://graphics.stanford.edu/data/3Dscanrep/). Environment map thanks to [Bernhard Vogl](http://dativ.at/lightprobes/index.html). == Transparent Machines == ![Frame 812](images/transparent-machines/frame812.png) 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 == ![Daylight villa](images/villa/villa-daylight.png height="200px") villa/ Modern indoor environment. Many thanks to Florent Boyer for this scene. Skylight environment map courtesy Nolan Goodnight. == Zero Day == ![Zero Day, Measure One, Frame 180](images/measure-one/frame180.png) 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).
