High-quality interactive path tracing

Abstract

Although still computationally expensive, path tracing is continually becoming more promising as a render technique for use in a production environment, due to the continuing increase in generally available compute power. We research the feasibility of path tracing in a scenario where high-quality images must be rendered at interactive rates, by integrating a path tracer in a product configurator framework and evaluating its performance. We evaluate the current state-of-the-art in path tracing postprocessing denoising filters, and propose our own novel filter aimed specifically at interactive path tracing, to reduce render times significantly.
