A 12 × 8 m lawn mown with a 46 cm deck. Left: before GR1, per 0.3 m cell, the same contrast whatever the angle. Right: v2, with the stripe map (4 texels a cell) written by the deck's real cut shape, contrast growing as you look lower across the lawn, sky sheen and shaded undersides, sun and cloud, and a roller twice as bold. Drag "Look down" to the top: v2's bands fade, as real ones do.
