On the Wall (photo mode) - fotojockovic.com/wall
================================================
Shows your picture on a photo of your wall as a framed print or a gallery-wrapped canvas, in true perspective
and size, relit from the photo. Everything runs in the browser; no image leaves the device.

Our own work: the frame, mat and canvas models (swept mouldings with mitred corners, bevel-cut mat with white
core, canvas fold), the wall calibration (homography, focal length estimate, pose), the photo analysis
(illumination field, light direction, black level, noise and sharpness estimates), the compositing shaders
(relighting, area-light wall shadow, recess shadow, glass reflection and glare, grain), the procedural
painted-wood relief, the UI and texts. Everything else that ships to the browser:
