A taos-engine simulation of a SimTable structured-light rig: a projector and two flanking cameras over shaped sand. Calibrates per-camera-pixel projector (u,v) coordinates via temporal phase-shift patterns, packs them into a 24-bit RGB raster (12 bits u, 12 bits v), and offers an FFT scrub mode for thinking about the global information in the camera images. **Read order** 1.
