EuCAP2025 - Comparing Differentiable and Dynamic Ray Tracing: Introducing the Multipath Lifetime Map

Our paper has been accepted to EuCAP 2025!

At EuCAP 2025, I presented our paper Comparing Differentiable and Dynamic Ray Tracing: Introducing the Multipath Lifetime Map (Eertmans et al., 2025). This work is the result of a collaboration with Pr. Degli-Esposti’s laboratory from University of Bologna, where I worked for 4 months in late 2024. In this work, we investigate review the Dynamic and Differentiable Ray Tracing techniques, methods that are rarily compared and often confused. Then, we study the limits of the extrapolation methodology on which Dynamic Ray Tracing relies, and provide a novel visual tool to better study those limits: the Multipath Lifetime Map.

Finally, an interative tutorial is available to guide the readers through the implementation of our presented tool and metrics.

Slides

The following slides are made with RevealJS and are interactive!

Use basic keys like LEFT and RIGHT to navigate through slides, or F to go full screen.

The slides were generated using the Manim (The Manim Community Developers, 2022) animation engine and Manim Slides (Eertmans, 2023), one of my open source projects, to combine the animations into slides and later convert them to a RevealJS .html file.

If you prefer, PowerPoint and PDF versions are also available.
