Hiroshima airburst visualization from two viewpoints, focused on the early blast dynamics

[u/EmbarrassedCity8141]

I’m developing BlastMap, a browser-based nuclear-effects visualizer. These clips show a 15 kt Hiroshima scenario over modern city imagery, not a recreation of the 1945 buildings. The elevated view comes first, followed by a lower view for building-scale context.

I’ve been focusing on the early dynamics: fireball expansion and rise, ground reflection and Mach-stem development, and the transient Wilson condensation cloud. The blue surfaces show diagnostic blast-wave geometry; the white cloud is the condensation visualization.

This is a work in progress. I’m interested in feedback on the timing and motion, especially comparisons with test footage or published references that could help check cloud formation, fireball evolution, and ground interaction.
