Antarang: a walkable 3D museum of Indian and world art

Indian art history usually appears in world-art timelines as a footnote. Antarang's premise is that it belongs on the same axis — Indus Valley to the Progressive Artists' Group alongside the Renaissance to Modernism — and that the way to feel that is to walk through it.

The gallery felt jittery, and the instinct is to chase frames per second. The bigger win was elsewhere: the centre-screen focus raycast — the check that decides which artwork you're looking at — ran every frame. Throttling it to roughly ten times a second improved perceived smoothness more than any frame-rate tuning did.

The same performance thinking runs through the build: an adaptive device-pixel-ratio capped at 1.8 with a performance monitor to hold 60 fps on weaker GPUs, the 3D code split out of the initial bundle, and dust motes and head-bob that switch off under reduced-motion settings.

A museum that treats Indian art as a first-class citizen of art history, built on a single permitted data source — and where copyright forbids a reproduction, a modern artist appears as a biography node rather than an invented image.
