Warning !!! Work in progress !!!
Does not work, but could be fun to fix.

MERF Unity Viewer

This repository contains the source code for a Unity port of the web viewer for MERF - Memory-Efficient Radiance Fields for Real-time View Synthesis in Unbounded Scenes[^1]

Please note, that this is an unofficial port. I am not affiliated with the original authors or their institution.

Known Issues

• Everything mostly works up to calculating the diffuse term of the volume. But the 'evaluateNetwork()' function in the shader seems to return unreasonably high values, probably due to some coordinate space or other platform-specific differences between the original Three.js viewer and Unity. Contributions welcome.
