Editing Cornell box (section)

== Scene Configuration ==
The basic environment consists of:
* A single [[light source]]
* A [[green]] right wall
* A [[red]] left wall
* A [[white]] back wall, floor, and ceiling

Objects are commonly placed inside the box to study their interaction with light. The original configuration included two boxes, while subsequent versions introduced a [[Reflection (physics)|reflective]] [[mirror]] [[sphere]] and a [[Refraction|refractive]] [[glass]] sphere, commonly used in [[Ray tracing (graphics)|ray tracing]] research.<ref>{{Cite book|last=Jensen|first=Henrik Wann|title=Realistic Image Synthesis Using Photon Mapping|year=2001|publisher=A.
