Minimizing Ray Tracing Memory Traffic through Quantized Structures and Ray Stream Tracing
Moritz Grauer, Johannes Hanika, Carsten Dachsbacher
Memory bandwidth constraints continue to be a significant limiting factor in ray tracing performance, particularly as scene complexity grows and computational capabilities outpace…

Neural Two-Level Monte Carlo Real-Time Rendering
Mikhail Dereviannykh, Dmitrii Klepikov, Johannes Hanika +1
We introduce an efficient Two-Level Monte Carlo (subset of Multi-Level Monte Carlo, MLMC) estimator for real-time rendering of scenes with global illumination. Using MLMC we split…

Regional Adaptive Metropolis Light Transport
Hisanari Otsu, Killian Herveau, Johannes Hanika +2
The design of the proposal distributions, and most notably the kernel parameters, are crucial for the performance of Markov chain Monte Carlo (MCMC) rendering. A poor selection of…
