The Reviewed of Ray Tracing Technology Optimization

Abstract

The technology of ray tracing is a graphics rendering technique that enables the simulation of realistic lighting effects, including accurate shadows, reflections, and refractions. The fundamental principle of ray tracing technology lies in the emission of one or more rays from the camera, which traverse along the path intersecting with objects within the scene. Subsequently, it computes the color and intensity of light based on object materials and light source positions, ultimately amalgamating these rays into a synthesized final image. Ray tracing technology enhances the authenticity and precision of graphics, albeit at the expense of substantial computational overhead and resource consumption, necessitating optimization for improved rendering efficiency and performance. The present paper provides a comprehensive overview of various optimization techniques employed in ray tracing technology, encompassing spatial acceleration structures, importance sampling, differential rendering, noise reduction, among others. Through rigorous experimentation and analysis, the advantages, disadvantages, and applicable scenarios of these methods are thoroughly examined.
