Cross-Platform Functional Programming Real-Time Path Tracing Rendering Engine

With advancements in graphics processing unit (GPU) hardware capabilities so too has the complexity of programming interfaces for computer graphics risen, potentially leading to difficulties in regards to designing, implementing and maintaining high-performance GPU-accelerated applications. This paper presents an implementation of a real-time path tracing rendering engine written in Rust using a functional programming based approach, which aims to simplify the development, maintenance and cross-platform compatibility of the modern computer graphics pipeline.
