Time-lapse playback
Fast-forward through dense simulation timelines without losing accurate timing or event sequencing.
The time-lapse engine preserves every keyframe and interpolated state while compressing playback speed. You can scrub through seconds, minutes, or hours of simulated time with precision, crucial for reviewing construction phasing or environmental exposure over days. The playback speed is linked to simulated time—not real-time—so one hour of real playback might equal two weeks of real-world duration, with no loss of accuracy.
Each frame in the timeline includes embedded metadata about boundary conditions and load states, ensuring that structural or behavioral transitions remain interpretable even at 50x speed. This allows engineers to spot subtle fatigue accumulation or sequence errors that might be missed in full-speed runs. Exported videos retain this fidelity, making them suitable for client reviews or regulatory submissions.
Playback controls include step-back, pause-on-event, and speed ramps—so you can slow down critical moments like crane boom rotation or scaffold release. The interface syncs simulation time with visual markers (e.g., shadows or load graphs) so temporal context remains anchored. No external plugins are needed; playback works in any modern browser with hardware acceleration.
