How it works

Each scene is a chunked .luxar.zarr store held on object storage. The viewer is deployed once and takes its dataset as a URL — ?src= — so every scene here is the same build pointed somewhere new. Nothing is downloaded up front: the viewer fetches only the chunks the current view needs.

What you're looking at

Points, lines, Gaussian splats and meshes, from a few hundred elements to tens of millions — light-sheet microscopy, connectomes, cosmology, single-cell embeddings. Scenes are nD: use the dimension controls to step through time, channels or any other axis a dataset carries.

The code

Luxar is open source at github.com/royerlab/luxar. Every scene here is produced by a script in packages/luxar/src/luxar/demos — each one runnable with luxar demo run <name>.
