Scenes for pbrt-v3

barcelona-pavilion: 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.

bathroom: Modern bathroom with soft indirect lighting and depth of field. Given the mirrors and bright wight walls, multi-bounce indirect illumination has a substantial effect on the overall appearance of the scene.

bmw-m6: BMW M6 car (model year 2006) illuminated by a realistic skylight model.

Thanks to Fred C. M'ule Jr. ("tyrant monkey" on BlendSwap) for this nice car model. CC-Zero (public domain) license. Downloaded from BlendSwap.

breakfast: Indoor scene with chairs around a table. One variant of the scene has light streaming in through blinds from the side such that most of the scene is only illuminated indirectly; finding these indirect illumination paths can be challenging. Another variant is only illuminated by the lights above the table; handling the resulting light transport through the glass light fixtures is a good challenge for many light transport algorithms.

buddha-fractal: Stanford Buddha model made out of Stanford Buddha models. 25,250 instances, each with 29,890 triangles, giving a total geometric complexity of over 750 million triangles.

Thanks for Guillermo M. Leal Llaguno for this fun variant of the Stanford Buddha model. (Buddha model courtesy Stanford Computer Graphics Laboratory.

bunny-fur: Stanford Bunny with fur growing out of it, modeled using the new curve shape added to pbrt in the third edition of the book. Over 1.5 million curves are used.

caustic-glass: A delightfully complex caustic pattern that results from light being projected through a realistic model of a bumpy glass. Thanks to Simon Wendsche for the model.

chopper-titan: Shiny motorcycle sitting on a glossy surface, illuminated by a sunset. Thanks to julioras3d for this model; CC-BY license. Downloaded from BlendSwap.

cloud: One scene with a bright white cloud, showing the effect of multiple scattering in participating media, and another, with the same volume density but with much more absorption, leading to a much darker cloud. The two images show the difference between highly-scattering and highly-absorptive media.

coffee-splash: A splash of coffee in a cup with a spoon, rendered using a complex simulated BRDF for the cup and saucer, and multiple scattering in participating media inside the splash.

contemporary-bathroom: Another contemporary bathroom scene. This scene is quite challenging to render without visible noise: specular light transport by the large mirror and the very small area light sources surrounded by glass in the light bulbs are difficult to render efficiently.

Abstract print seen in mirror based on a smoke photograph by Vanessa Pike-Russell, CC-BY license; the photo was inverted and contrast was adjusted for rendering.

crown: 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.

dambreak: two frames of a fluid simlulation from Yining Karl Li's nifty Ariel fluid simulator.

dragon: A scanned dragon model rendered with many different materials, showing off the visual differences between them. Dragon model courtesy Christian Schüller. Environment map thanks to Bernhard Vogl.

ecosys: Fairly complex outdoor scene with many plants and trees, illuminated by an environment map. This scene was used for the cover image for the first edition of Physically Based Rendering. Scene from Deussen et al., Realistic modeling and rendering of plant ecosystems.

ganesha: 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: Scenes with both curly and straight hair show off the hair scattering model implemented in The Implementation of a Hair Scattering Model.

measure-one: 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!)

License: "These files are available under a sort of "open source" concept. They are intended for educational use but really can be used for whatever the fuck you want. You don't need to credit me for whatever commercial or non-commercial use you make of them, but if you could shout me a holla with any project that do come from them, I'd love to see it :)"
