Unlike rasterization, which draws and shades triangles individually, ray tracing simulates propagation of light between surfaces in a scene and enables advanced effects such as transparency, shadows, and ambient occlusion--effects not easily accomplished in other massive-model rendering approaches. This article describes the application of ray tracing to several aircraft manufacturing scenarios.
