The clearing floor is level packed dirt scattered with moss, fallen needles and short grass, roughly 35 metres across from treeline to treeline, leaving a large empty central area. A bare dirt track about 4 metres wide runs straight through the clearing from one side to the other, its surface smooth, dry and rutted. Near the front edge of the clearing, just off the track, stands a single broad grey granite boulder with a flat level top about 1.6 metres by 1.2 metres and about 0.8 metres above the ground.", "surfaces": [ { "name": "clearing floor (packed dirt, moss and needles)", "dims_m": "35 across", "height_m": 0.0, "suits": ["small", "medium", "large"] }, { "name": "dirt track through the clearing", "dims_m": "4 wide x 35 long", "height_m": 0.0, "suits": ["medium", "large"] }, { "name": "flat top of the granite boulder (near-field)", "dims_m": "1.6 x 1.2", "height_m": 0.8, "suits": ["small", "medium"] } ], "flags": { "infeasible": [ { "object": "train", "why": "A train read as a train requires multiple coupled cars, well over 50 m; the clearing is only 35 m across and bounded by dense trunks, so it cannot fit at true scale." } ], "foreground_background_blur": [ { "object": "tree", "subtype": "duplication", "why": "The backdrop is unavoidably composed of Ver más
