View source for List of common 3D test models

{{short description|none}}

This is a list of [[3D modeling|models]] and [[Polygon mesh|meshes]] commonly used in [[3D computer graphics]] for testing and demonstrating [[Rendering (computer graphics)|rendering]] algorithms and [[visual effects]]. Their use is important for comparing results, similar to the way [[standard test image]]s are used in [[image processing]].

== Modelled ==

Designed using CAD software; sorted by year of [[3D modeling|modelling]].

| [[Cornell box]]
| [[File:BMRT - Cornell box radiosity.png|none|160x160px]]
| 1984
| [[Cindy M. Goral]], [[Kenneth E. Torrance]], [[Donald P. Greenberg]], [[Bennett Battaile]] at [[Cornell University]]
| Originally meant to be compared to real-life setup to test physicality of simulated optics
| 5 quads, 1 light source
|
| Scene includes multiple models and light source. Many versions exist, but only one of them is considered the standard Cornell box; the color of the left and right walls is important.
