Gumaru

Gumaru is an interactive historical atlas and spatial archive engine that renders history as a living 3D space.

Blending physical geography with database constraints, it features a 3D globe styled like a vintage parchment map, offline high-resolution terrain tiles, and static 3D models. It tracks timelines and family graphs chronologically, letting you navigate land deeds, diaries, and hypotheses with certainty thresholds.

The engine includes an offline text-to-speech pipeline that generates voiceover narration for timeline events, and supports scripted cinematic scenes with animated cameras and 3D primitives. Gumaru allows you to export your projects as static HTML5 websites that can be experienced on desktop and mobile. Its capabilities are demonstrated in the interactive story of the Rain Cloud Teapot, which traces a century-long Eurasian family migration.
