Speeding Up a Fat Web Client

"Occlusion culling is a technique that came out of the video gaming industry where you render what is actually visible at a given time."

I don't have any proof handy, but I imagine this was leveraged in areas outside of gaming.

Spreadsheets seem likely to have used this, for example.

What they're doing isn't even occlusion culling. It's frustum culling.

edit: I wouldn't even call it frustum calling since I don't think frustum culling makes much sense in a retained mode API (the frustum culling happens when rendering the retained mode representation through the underlying immediate mode API). 'Level of detail' maybe.

For one of our client, Adya[1], our team at Alaris Prime[2] implemented the very same idea for the web. It is a file manager that displays a huge list of folders/files from multiple clouds (file storage) providers. We needed a fast-loading, smooth UX and way to do it was to move things around as little as possible - only the visible viewport of the user's browser.

We should be writing a case study on it but never got around to doing it.

Yes, lots of things also use "virtual scrolling"

iOS (And probably Android nowadays as well) list views is another example where it's been used for a long time.
