Build Log — Algorithms

chitra.art art algorithms | in progress

Deep zoom pyramids and the browser.

A placeholder for the eventual write-up on going from a single composite to a DZI tile pyramid: why levels are sized the way they are, what OpenSeadragon expects, and how storage layout shapes perceived load.

Status: draft outline. Will be replaced with measured numbers from real artworks once the pipeline is finalized.

Planned sections

DZI format basics — levels, tile size, overlap, format.
Pyramid generation — downsampling filters and cost.
Browser side — OpenSeadragon source config and caching.
Storage layout — flat blobs vs. nested, CDN behavior.
Cost — bytes per gigapixel, cold-load vs. warm-load.

Open questions

What tile size best balances request count vs. waste?
How does AVIF affect total pyramid weight at the same fidelity?
What's the right preload strategy for an opening overview?
