A sphere becomes a world.

The pinned panorama source builds a PerspectiveCamera, an inward-scaled SphereGeometry(500, 60, 40), and a TextureLoader-backed sRGB photo. Pointer drag changes longitude/latitude, wheel input clamps FOV, and the animation loop advances the view. This local study keeps those seams observable with deterministic equirectangular texture data.

The official 2294472375_24a3b8ef46_o.jpg, exact photo projection/page/pixel presentation, camera interaction timing, browser/device/backend breadth, texture/image matrices, and whole-example fidelity remain separate boundaries.
