Most renderers are remembered for their algorithms. Tungsten is remembered for what came in the scenes folder — eight rooms that became the field's shared test corpus. Open any rendering paper since 2015 and the figures are these rooms. Different renderer. Same room. The author wrote a path tracer for his master's thesis and the rendering community kept the furniture.

Eight rooms · one set of furniture · the entire field, twenty years. The corpus is the contribution.

The renderer is unmaintained now. The author moved to Disney, then to NVIDIA, then to other questions.

But every SIGGRAPH paper since 2015 has rendered his living room. The corpus outlived the code.

— Lineage of the Corpus —

1985Cornell University publishes the original Cornell Box. The first standardized rendering test scene.
1997Eric Veach's PhD introduces the Veach Door as a hard-light test for Metropolis Light Transport.
2012Bitterli releases the Living Room. First widely-shared modern interior in PBRT-compatible format.
2014Tungsten 1.0. Master's thesis. Kitchen, Bathroom, Bedroom join the catalog.
2015Bitterli Resources website published. The corpus becomes public infrastructure for the field.
2016Author joins Disney Research. Renderer slows; corpus accelerates.
2018Author joins NVIDIA Research. Tungsten code paused — the scenes circulate everywhere.
Every Mitsuba 3 paper, every PBRT v4 figure, every real-time path-tracing demo — the same eight rooms.
