  • •Rust + Slint delivers native performance with cross-platform support
  • •GPU-accelerated augmentation pipeline shows real engineering consideration
Weaknesses
  • •Only 7 stars and 0 forks signals very early adoption and untested stability

Post Description

Hey HN!

I built a fast native cross-platform open-source image viewer called Luminous in Rust/Slint UI.

The main features:

- Mainly focused on performance

- Extensible via plugins - either shared libraries or IPC-based

- Plugins such as SAM 3 for annotation and CLIP for semantic search/filtering

- GPU-accelerated augmentation pipeline

Still in active development. Would love your feedback!
