Arnold is based on Monte Carlo Ray Tracing. Its engine is optimized to send billions of spatially incoherent rays throughout a scene. It often uses one level of diffuse inter-reflection so that light can bounce off of a wall or other object and indirectly illuminate a subject. For complex scenes such as the space station in Elysium, it makes heavy use of instancing. It uses the Open Shading Language to define the materials and textures.
Marcos Fajardo is the chief architect of Arnold. The beginnings of what is now Arnold emerged in 1997 when Fajardo decided to write his own renderer. That year, he attended SIGGRAPH, where his interest in stochastic ray tracing (a foundational part of Arnold's rendering technology) was piqued in discussions with friends attending the conference.
On 4 January 2017, the Academy of Motion Picture Arts and Sciences recognized Fajardo with a Scientific and Engineering award (Academy plaque) for "the creative vision and original implementation of the Arnold Renderer."
