Show HN: Interactive HDR and Wide-Gamut WebGPU Planetary Elevation Visualization

https://agaura.github.io/elevation_atlas/index.html

Built an elevation map visualization which includes data for the Earth, the Moon, and Mars. Makes use of rendering to device pixels instead of CSS pixels so it visualizes densely and crisply on capable displays, and most notably, renders in WebGPU and outputs in HDR and P3 with custom color maps so the visualization looks particularly vibrant. HDR and wide-gamut support varies by display, but...

A simple interactive visualization of chromaticity and display gamuts using animated point clouds. It compares sRGB, P3, Rec.2020, and a computed “max gamut,” shows how the visible spectrum maps onto chromaticities, and highlights out-of-gamut regions through desaturation.
