Painting Rooms
Step inside the paintings.
Each canvas is treated as a photograph. Its perspective gives a camera, the camera gives metres, and the metres become a clay room you can walk through and light.
The Calling of Saint Matthew
Where does the beam of light really come from, and how deep is the room it crosses?
Enter the room →Las Meninas
Who is the mirror showing, the king and queen or the canvas? Four theories, each tested.
Enter the room →A Bar at the Folies-Bergère
The barmaid's reflection is in the wrong place. Can any single viewpoint explain it?
Enter the room →The Daughters of Edward Darley Boit
One room, three possible light sources. Which combination makes the painting?
Enter the room →Measure
Vanishing points give the camera. Where figures meet the floor gives depth. Bottles, tables and doors of known size give the scale.
Rebuild
Every figure and object is placed from its pixels in metres. Fade the original over the model to see where they agree.
Light
Switch to path tracing and the light bounces for real: soft shadows, and mirrors that show what they would actually show.
