DREVERSED is an experimental demo about time, physics and simulation.
Each sequence is a reversed replay of a physics simulation computed in real time during the previous segment.
The project explores the irreversibility of physical processes - a direct echo to Loschmidt’s paradox.
DREVERSED was created for API8, a demoscene-inspired event at Paris 8 University blending research, real-time art and education.
It was (semi) intentionally designed not to behave identically on every machine, embracing the unstable identity of digital time.
- Released at API8 2025 (Université Paris 8) – not ranked
- Written in Lua, using the Harfang 3D engine
- Runs on Windows (x64, DX11) and Linux (x64, OpenGL)
This demo captures each physical scene by recording world matrices of each physical object, frame-by-frame.
Replay is not a fixed timeline — it’s stretched, looped, reversed.
Timing may vary depending on your monitor's refresh rate. 60Hz is optimal.
