From Ultra HDR to Space HDR: gain maps, viewpoints and HDR browser output

[sansi-lcj]

This repository makes Realsee’s HDR panorama-viewing capability available as an open-source project.

The engineering article connects the Ultra HDR gain-map approach with a wider spatial pipeline: RAW capture, online image resources, viewpoint navigation and HDR presentation. It explains how base imagery and gain data share sampling directions, how finer detail stays coordinated, and how recovered light is carried through floating-point rendering.

Space HDR brings these pieces into a navigable space, aiming to preserve more of the scene’s light as people explore it. The article provides the wider context for this repository’s panorama-viewing capability, together with an interactive spatial example.
